-- **Nuvoton:** NUC120, NUC121/NUC125, NUC126, NUC505
-- **NXP:**
-  - iMX RT Series: RT1011, RT1015, RT1021, RT1052, RT1062, RT1064
-  - Kinetis: KL25
-  - LPC Series: 11u, 13, 15, 17, 18, 40, 43, 51u, 54, 55
-- **Raspberry Pi:** RP2040
-- **Renesas:** RX63N
-- **Silabs:** EFM32GG12
-- **Sony:** CXD56
-- **ST:** STM32 series: L0, F0, F1, F2, F3, F4, F7, H7 both FullSpeed and HighSpeed

-
-[Here is the list of supported Boards](docs/boards.md) that can be used with provided examples.
-
-## Device Stack
-
-Supports multiple device configurations by dynamically changing usb descriptors. Low power functions such like suspend, resume, and remote wakeup. Following device classes are supported:
-
-- Audio Class 2.0 (UAC2) still work in progress
-- Bluetooth Host Controller Interface (BTH HCI)
-- Communication Class (CDC)
-- Device Firmware Update (DFU): DFU mode (WIP) and Runtinme 
-- Human Interface Device (HID): Generic (In & Out), Keyboard, Mouse, Gamepad etc ...
-- Mass Storage Class (MSC): with multiple LUNs
-- Musical Instrument Digital Interface (MIDI)
-- Network with RNDIS, CDC-ECM (work in progress)
-- USB Test and Measurement Class (USBTMC)
-- Vendor-specific class support with generic In & Out endpoints. Can be used with MS OS 2.0 compatible descriptor to load winUSB driver without INF file.
-- [WebUSB](https://github.com/WICG/webusb) with vendor-specific class
-
-If you have special need, `usbd_app_driver_get_cb()` can be used to write your own class driver without modifying the stack. Here is how RPi team add their reset interface [raspberrypi/pico-sdk#197](https://github.com/raspberrypi/pico-sdk/pull/197)
-
-## Host Stack
-
-**Most active development is on the Device stack. The Host stack is under rework and largely untested.**
-
-- Human Interface Device (HID): Keyboard, Mouse, Generic
-- Mass Storage Class (MSC)
-- Hub currently only supports 1 level of hub (due to my laziness)
-
-## OS Abstraction layer
-
-TinyUSB is completely thread-safe by pushing all ISR events into a central queue, then process it later in the non-ISR context task function. It also uses semaphore/mutex to access shared resources such as CDC FIFO. Therefore the stack needs to use some of OS's basic APIs. Following OSes are already supported out of the box.
-
-- **No OS**
-- **FreeRTOS**
-- **Mynewt** Due to the newt package build system, Mynewt examples are better to be on its [own repo](https://github.com/hathach/mynewt-tinyusb-example) 
-
-## Getting Started
-
-[Here are the details for getting started](docs/getting_started.md) with the stack.
-
-## Porting
-
-Want to help add TinyUSB support for a new MCU? Read [here](docs/porting.md) for an explanation on the low-level API needed by TinyUSB.
-

-# Boards
-
-The board support code is only used for self-contained examples and testing. It is not used when TinyUSB is part of a larger project. It is responsible for getting the MCU started and the USB peripheral clocked with minimal of on-board devices
-- One LED : for status
-- One Button : to get input from user
-- One UART : optional for device, but required for host examples

-If you don't possess any of supported board above. Don't worry you can easily implemented your own one by following this guide as long as the mcu is supported.
-
-- Create new makefile for your board at `hw/bsp/<board name>/board.mk` and linker file as well if needed.
-- Create new source file for your board at `hw/bsp/<board name>/<board name>.c` and implement following APIs

-Is responsible for starting the MCU, setting up the USB clock and USB pins. It is also responsible for initializing LED and button pins.
-One useful clock debugging technique is to set up a PWM output at a known value such as 500hz based on the USB clock so that you can verify it is correct with a logic probe or oscilloscope.
-Setup your USB in a crystal-less mode when available. That makes the code easier to port across boards.
-
-#### board_led_write()
-
-Set the pin corresponding to the led to output a value that lights the LED when `state` is true.
-
-#### board_button_read()
-
-Return current state of button, a `1` means active (pressed), a `0` means inactive.
-
-#### board_millis()
-
-The function returns the elapsed number of milliseconds since startup. On ARM this is commonly done with SysTick or Timer. This provide examples a way to measure time to blink LED or delay properly. It is only required when run examples without RTOS `CFG_TUSB_OS == OPT_OS_NONE`.

-## Register defs
+Register defs
+-------------
 
 The first step to adding support is including the register definitions and startup code for the
 microcontroller in TinyUSB. We write the TinyUSB implementation against these structs instead of higher level functions to keep the code small and to prevent function name collisions in linking of larger projects. For ARM microcontrollers this is the CMSIS definitions. They should be

+Build

-## Build
 Now that those directories are in place, we can start our iteration process to get the example building successfully. To build, run from the root of TinyUSB:
 
-`make -C examples/device/cdc_msc BOARD=<board>`
+``make -C examples/device/cdc_msc BOARD=<board>``
 
 Unless, you've read ahead, this will fail miserably. Now, lets get it to fail less by updating the files in the board directory. The code in the board's directory is responsible for setting up the microcontroller's clocks and pins so that USB works. TinyUSB itself only operates on the USB peripheral. The board directory also includes information what files are needed to build the example.
 
-One of the first things to change is the `-DCFG_TUSB_MCU` cflag in the `board.mk` file. This is used to tell TinyUSB what platform is being built. So, add an entry to `src/tusb_option.h` and update the CFLAG to match.

Duplicate one of the other sources from ``src/portable`` into ``src/portable/<vendor>/<chip_family>`` and delete all of the implementation internals. We'll cover what everything there does later. For now, get it compiling.

+Endpoints

 Endpoints are the core of the USB data transfer process. They come in a few forms such as control, isochronous, bulk, and interrupt. We won't cover the details here except with some caveats in open below. In general, data is transferred by setting up a buffer of a given length to be transferred on a given endpoint address and then waiting for an interrupt to signal that the transfer is finished. Further details below.
 
-Endpoints within USB have an address which encodes both the number and direction of an endpoint. TinyUSB provides `tu_edpt_number` and `tu_edpt_dir` to unpack this data from the address. Here is a snippet that does it.

 number and direction which usually determines where to write the buffer info. The buffer and its length are usually
 written to a specific location in memory and the peripheral is told the data is valid. (Maybe by writing a 1 to a

 At this point you should have everything working! ;-) Of course, you may not write perfect code. Here are some tips and tricks for debugging.
 
-Use [WireShark](https://www.wireshark.org/) or [a Beagle](https://www.totalphase.com/protocols/usb/) to sniff the USB traffic. When things aren't working its likely very early in the USB enumeration process. Figuring out where can help clue in where the issue is. For example:

+

 * If the host sends a SETUP packet and its not ACKed then your USB peripheral probably isn't started correctly.
 * If the peripheral is started correctly but it still didn't work, then verify your usb clock is correct. (You did output a PWM based on it right? ;-) )
-* If the SETUP packet is ACKed but nothing is sent back then you interrupt handler isn't queueing the setup packet correctly. (Also, if you are using your own code instead of an example `tud_task` may not be called.) If thats OK, the `dcd_xfer_complete` may not be setting up the next transaction correctly.

-# Getting Started #
-
-## Add TinyUSB to your project
-
-It is relatively simple to incorporate tinyusb to your (existing) project
-
-- Copy or `git submodule` this repo into your project in a subfolder. Let's say it is *your_project/tinyusb*
-- Add all the .c in the `tinyusb/src` folder to your project
-- Add *your_project/tinyusb/src* to your include path. Also make sure your current include path also contains the configuration file tusb_config.h.
-- Make sure all required macros are all defined properly in tusb_config.h (configure file in demo application is sufficient, but you need to add a few more such as CFG_TUSB_MCU, CFG_TUSB_OS since they are passed by IDE/compiler to maintain a unique configure for all boards).
-- If you use the device stack, make sure you have created/modified usb descriptors for your own need. Ultimately you need to implement all **tud_descriptor_** callbacks for the stack to work.
-- Add tusb_init() call to your reset initialization code.
-- Call `tud_int_handler()` (device) and/or `tuh_int_handler()` (host) in your USB IRQ Handler
-- Implement all enabled classes's callbacks.
-- If you don't use any RTOSes at all, you need to continuously and/or periodically call tud_task()/tuh_task() function. All of the callbacks and functionality are handled and invoked within the call of that task runner.
-
-~~~{.c}
-int main(void)
-{
-  your_init_code();
-  tusb_init(); // initialize tinyusb stack
-
-  while(1) // the mainloop
-  {
-    your_application_code();
-
-    tud_task(); // device task
-    tuh_task(); // host task
-  }
-}
-~~~
-
-## Examples
-
-For your convenience, TinyUSB contains a handful of examples for both host and device with/without RTOS to quickly test the functionality as well as demonstrate how API() should be used. Most examples will work on most of [the supported Boards](boards.md). Firstly we need to `git clone` if not already
-
-```
-$ git clone https://github.com/hathach/tinyusb tinyusb
-$ cd tinyusb
-```
-
-Some TinyUSB examples also requires external submodule libraries in `/lib` such as FreeRTOS, Lightweight IP to build. Run following command to fetch them 
-
-```
-$ git submodule update --init lib
-```
-
-In addition, MCU driver submodule is also needed to provide low-level MCU peripheral's driver. Luckily, it will be fetched if needed when you run the `make` to build your board.
-
-Note: some examples especially those that uses Vendor class (e.g webUSB) may requires udev permission on Linux (and/or macOS) to access usb device. It depends on your OS distro, typically copy `/examples/device/99-tinyusb.rules` file to /etc/udev/rules.d/ then run `sudo udevadm control --reload-rules && sudo udevadm trigger` is good enough.
-
-### Build
-
-To build example, first change directory to an example folder. 
-
-```
-$ cd examples/device/cdc_msc
-```
-
-Then compile with `make BOARD=[board_name] all`, for example
-
-```
-$ make BOARD=feather_nrf52840_express all
-```
-
-Note: `BOARD` can be found as directory name in `hw/bsp`, either in its family/boards or directly under bsp (no family).
-
-#### Port Selection
-
-If a board has several ports, one port is chosen by default in the individual board.mk file. Use option `PORT=x` To choose another port. For example to select the HS port of a STM32F746Disco board, use:
-
-```
-$ make BOARD=stm32f746disco PORT=1 all
-```
-
-#### Port Speed
-
-A MCU can support multiple operational speed. By default, the example build system will use the fastest supported on the board. Use option `SPEED=full/high` e.g To force F723 operate at full instead of default high speed
-
-```
-$ make BOARD=stm32f746disco SPEED=full all
-```
-
-### Debug
-
-To compile for debugging add `DEBUG=1`, for example
-
-```
-$ make BOARD=feather_nrf52840_express DEBUG=1 all
-```
-
-#### Log
-
-Should you have an issue running example and/or submitting an bug report. You could enable TinyUSB built-in debug logging with optional `LOG=`. LOG=1 will only print out error message, LOG=2 print more information with on-going events. LOG=3 or higher is not used yet. 
-
-```
-$ make BOARD=feather_nrf52840_express LOG=2 all
-```
-
-#### Logger
-
-By default log message is printed via on-board UART which is slow and take lots of CPU time comparing to USB speed. If your board support on-board/external debugger, it would be more efficient to use it for logging. There are 2 protocols: 
-
-- `LOGGER=rtt`: use [Segger RTT protocol](https://www.segger.com/products/debug-probes/j-link/technology/about-real-time-transfer/)   
-  - Cons: requires jlink as the debugger.
-  - Pros: work with most if not all MCUs
-  - Software viewer is JLink RTT Viewer/Client/Logger which is bundled with JLink driver package.
-- `LOGGER=swo`: Use dedicated SWO pin of ARM Cortex SWD debug header.
-  - Cons: only work with ARM Cortex MCUs minus M0
-  - Pros: should be compatible with more debugger that support SWO.
-  - Software viewer should be provided along with your debugger driver.
-
-```
-$ make BOARD=feather_nrf52840_express LOG=2 LOGGER=rtt all
-$ make BOARD=feather_nrf52840_express LOG=2 LOGGER=swo all
-```
-
-### Flash
-
-`flash` target will use the default on-board debugger (jlink/cmsisdap/stlink/dfu) to flash the binary, please install those support software in advance. Some board use bootloader/DFU via serial which is required to pass to make command
-
-```
-$ make BOARD=feather_nrf52840_express flash
-$ make SERIAL=/dev/ttyACM0 BOARD=feather_nrf52840_express flash
-```
-
-Since jlink can be used with most of the boards, there is also `flash-jlink` target for your convenience.
-
-```
-$ make BOARD=feather_nrf52840_express flash-jlink
-```
-
-Some board use uf2 bootloader for drag & drop in to mass storage device, uf2 can be generated with `uf2` target
-
-```
-$ make BOARD=feather_nrf52840_express all uf2
-```

-# Concurrency
+***********
+Concurrency
+***********
 
 The TinyUSB library is designed to operate on single-core MCUs with multi-threaded applications in mind. Interaction with interrupts is especially important to pay attention to.
 It is compatible with optionally using a RTOS.
 
-## General
+General
+-------
 
 When writing code, keep in mind that the OS (if using a RTOS) may swap out your code at any time. Also, your code can be preempted by an interrupt at any time.
 
-## Application Code
+Application Code
+----------------
 
 The USB core does not execute application callbacks while in an interrupt context. Calls to application code are from within the USB core task context. Note that the application core will call class drivers from within their own task.
 
-## Class Drivers
+Class Drivers
+-------------
 
 Class driver code should never be called from an interrupt context by the USB core, though the application is allowed to call class driver functions from interrupts. USB core functions may be called simultaneously by multiple tasks. Use care that proper locking is used to guard the USBD core functions from this case.
 
-Class drivers are allowed to call `usbd_*` functions, but not `dcd_*` functions.

 Much of the processing of the USB stack is done in an interrupt context, and care must be taken in order to ensure variables are handled in the appropriate ways by the compiler and optimizer.
 
 In particular:
 
-- Ensure that all memory-mapped registers (including packet memory) are marked as volatile. GCC's optimizer will even combine memory access (like two 16-bit to be a 32-bit) if you don't mark the pointers as volatile. On some architectures, this can use macros like `_I`, `_O`, or `_IO'.
-- All defined global variables are marked as  `static`.

+***************
+Getting Started
+***************
+
+Add TinyUSB to your project
+---------------------------
+
+It is relatively simple to incorporate tinyusb to your (existing) project
+
+
+* Copy or ``git submodule`` this repo into your project in a subfolder. Let's say it is *your_project/tinyusb*
+* Add all the .c in the ``tinyusb/src`` folder to your project
+* Add *your_project/tinyusb/src* to your include path. Also make sure your current include path also contains the configuration file tusb_config.h.
+* Make sure all required macros are all defined properly in tusb_config.h (configure file in demo application is sufficient, but you need to add a few more such as CFG_TUSB_MCU, CFG_TUSB_OS since they are passed by IDE/compiler to maintain a unique configure for all boards).
+* If you use the device stack, make sure you have created/modified usb descriptors for your own need. Ultimately you need to implement all **tud descriptor** callbacks for the stack to work.
+* Add tusb_init() call to your reset initialization code.
+* Call ``tud_int_handler()`` (device) and/or ``tuh_int_handler()`` (host) in your USB IRQ Handler
+* Implement all enabled classes's callbacks.
+* If you don't use any RTOSes at all, you need to continuously and/or periodically call tud_task()/tuh_task() function. All of the callbacks and functionality are handled and invoked within the call of that task runner.
+
+.. code-block::
+
+   int main(void)
+   {
+     your_init_code();
+     tusb_init(); // initialize tinyusb stack
+
+     while(1) // the mainloop
+     {
+       your_application_code();
+
+       tud_task(); // device task
+       tuh_task(); // host task
+     }
+   }
+
+Examples
+--------
+
+For your convenience, TinyUSB contains a handful of examples for both host and device with/without RTOS to quickly test the functionality as well as demonstrate how API() should be used. Most examples will work on most of `the supported Boards <boards.md>`_. Firstly we need to ``git clone`` if not already
+
+.. code-block::
+
+   $ git clone https://github.com/hathach/tinyusb tinyusb
+   $ cd tinyusb
+
+Some TinyUSB examples also requires external submodule libraries in ``/lib`` such as FreeRTOS, Lightweight IP to build. Run following command to fetch them 
+
+.. code-block::
+
+   $ git submodule update --init lib
+
+In addition, MCU driver submodule is also needed to provide low-level MCU peripheral's driver. Luckily, it will be fetched if needed when you run the ``make`` to build your board.
+
+Note: some examples especially those that uses Vendor class (e.g webUSB) may requires udev permission on Linux (and/or macOS) to access usb device. It depends on your OS distro, typically copy ``/examples/device/99-tinyusb.rules`` file to /etc/udev/rules.d/ then run ``sudo udevadm control --reload-rules && sudo udevadm trigger`` is good enough.
+
+Build
+^^^^^
+
+To build example, first change directory to an example folder. 
+
+.. code-block::
+
+   $ cd examples/device/cdc_msc
+
+Then compile with ``make BOARD=[board_name] all``\ , for example
+
+.. code-block::
+
+   $ make BOARD=feather_nrf52840_express all
+
+Note: ``BOARD`` can be found as directory name in ``hw/bsp``\ , either in its family/boards or directly under bsp (no family).
+
+Port Selection
+~~~~~~~~~~~~~~
+
+If a board has several ports, one port is chosen by default in the individual board.mk file. Use option ``PORT=x`` To choose another port. For example to select the HS port of a STM32F746Disco board, use:
+
+.. code-block::
+
+   $ make BOARD=stm32f746disco PORT=1 all
+
+Port Speed
+~~~~~~~~~~
+
+A MCU can support multiple operational speed. By default, the example build system will use the fastest supported on the board. Use option ``SPEED=full/high`` e.g To force F723 operate at full instead of default high speed
+
+.. code-block::
+
+   $ make BOARD=stm32f746disco SPEED=full all
+
+Debug
+^^^^^
+
+To compile for debugging add ``DEBUG=1``\ , for example
+
+.. code-block::
+
+   $ make BOARD=feather_nrf52840_express DEBUG=1 all
+
+Log
+~~~
+
+Should you have an issue running example and/or submitting an bug report. You could enable TinyUSB built-in debug logging with optional ``LOG=``. LOG=1 will only print out error message, LOG=2 print more information with on-going events. LOG=3 or higher is not used yet. 
+
+.. code-block::
+
+   $ make BOARD=feather_nrf52840_express LOG=2 all
+
+Logger
+~~~~~~
+
+By default log message is printed via on-board UART which is slow and take lots of CPU time comparing to USB speed. If your board support on-board/external debugger, it would be more efficient to use it for logging. There are 2 protocols: 
+
+
+* `LOGGER=rtt`: use [Segger RTT protocol](https://www.segger.com/products/debug-probes/j-link/technology/about-real-time-transfer/)   
+
+  * Cons: requires jlink as the debugger.
+  * Pros: work with most if not all MCUs
+  * Software viewer is JLink RTT Viewer/Client/Logger which is bundled with JLink driver package.
+
+* ``LOGGER=swo``\ : Use dedicated SWO pin of ARM Cortex SWD debug header.
+
+  * Cons: only work with ARM Cortex MCUs minus M0
+  * Pros: should be compatible with more debugger that support SWO.
+  * Software viewer should be provided along with your debugger driver.
+
+.. code-block::
+
+   $ make BOARD=feather_nrf52840_express LOG=2 LOGGER=rtt all
+   $ make BOARD=feather_nrf52840_express LOG=2 LOGGER=swo all
+
+Flash
+^^^^^
+
+``flash`` target will use the default on-board debugger (jlink/cmsisdap/stlink/dfu) to flash the binary, please install those support software in advance. Some board use bootloader/DFU via serial which is required to pass to make command
+
+.. code-block::
+
+   $ make BOARD=feather_nrf52840_express flash
+   $ make SERIAL=/dev/ttyACM0 BOARD=feather_nrf52840_express flash
+
+Since jlink can be used with most of the boards, there is also ``flash-jlink`` target for your convenience.
+
+.. code-block::
+
+   $ make BOARD=feather_nrf52840_express flash-jlink
+
+Some board use uf2 bootloader for drag & drop in to mass storage device, uf2 can be generated with ``uf2`` target
+
+.. code-block::
+
+   $ make BOARD=feather_nrf52840_express all uf2
+
+IAR Support
+-----------
+
+IAR Project Connection files are provided to import TinyUSB stack into your project.
+
+* A buldable project of your MCU need to be created in advance.
+
+
+  * Take example of STM32F0:
+  
+    -  You need `stm32l0xx.h`, `startup_stm32f0xx.s`, `system_stm32f0xx.c`.
+
+    - `STM32L0xx_HAL_Driver` is only needed to run examples, TinyUSB stack itself doesn't rely on MCU's SDKs.
+
+* Open `Tools -> Configure Custom Argument Variables` (Switch to `Global` tab if you want to do it for all your projects) 
+   Click `New Group ...`, name it to `TUSB`, Click `Add Variable ...`, name it to `TUSB_DIR`, change it's value to the path of your TinyUSB stack,
+   for example `C:\\tinyusb`
+
+Import stack only
+^^^^^^^^^^^^^^^^^
+
+1. Open `Project -> Add project Connection ...`, click `OK`, choose `tinyusb\\tools\\iar_template.ipcf`.
+
+Run examples
+^^^^^^^^^^^^
+
+1. (Python3 is needed) Run `iar_gen.py` to generate .ipcf files of examples:
+
+   .. code-block::
+
+     cd C:\tinyusb\tools
+     python iar_gen.py
+
+2. Open `Project -> Add project Connection ...`, click `OK`, choose `tinyusb\\examples\\(.ipcf of example)`.
+   For example `C:\\tinyusb\\examples\\device\\cdc_msc\\iar_cdc_msc.ipcf`

+
+Device Stack
+============
+
+Supports multiple device configurations by dynamically changing usb descriptors. Low power functions such like suspend, resume, and remote wakeup. Following device classes are supported:
+
+-  Audio Class 2.0 (UAC2)
+-  Bluetooth Host Controller Interface (BTH HCI)
+-  Communication Class (CDC)
+-  Device Firmware Update (DFU): DFU mode (WIP) and Runtinme
+-  Human Interface Device (HID): Generic (In & Out), Keyboard, Mouse, Gamepad etc ...
+-  Mass Storage Class (MSC): with multiple LUNs
+-  Musical Instrument Digital Interface (MIDI)
+-  Network with RNDIS, CDC-ECM (work in progress)
+-  USB Test and Measurement Class (USBTMC)
+-  Vendor-specific class support with generic In & Out endpoints. Can be used with MS OS 2.0 compatible descriptor to load winUSB driver without INF file.
+-  `WebUSB <https://github.com/WICG/webusb>`__ with vendor-specific class
+
+If you have special need, `usbd_app_driver_get_cb()` can be used to write your own class driver without modifying the stack. Here is how RPi team add their reset interface [raspberrypi/pico-sdk#197](https://github.com/raspberrypi/pico-sdk/pull/197)
+
+Host Stack
+==========
+
+- Human Interface Device (HID): Keyboard, Mouse, Generic
+- Mass Storage Class (MSC)
+- Hub currently only supports 1 level of hub (due to my laziness)
+
+OS Abstraction layer
+====================
+
+TinyUSB is completely thread-safe by pushing all ISR events into a central queue, then process it later in the non-ISR context task function. It also uses semaphore/mutex to access shared resources such as CDC FIFO. Therefore the stack needs to use some of OS's basic APIs. Following OSes are already supported out of the box.
+
+- **No OS**
+- **FreeRTOS**
+- **Mynewt** Due to the newt package build system, Mynewt examples are better to be on its [own repo](https://github.com/hathach/mynewt-tinyusb-example)
+
+License
+=======
+
+All TinyUSB sources in the `src` folder are licensed under MIT license. However, each file can be individually licensed especially those in `lib` and `hw/mcu` folder. Please make sure you understand all the license term for files you use in your project.
