TinyUSB

TinyUSB is an open-source cross-platform USB Host/Device stack for embedded system.

Device Stack

Human Interface Device (HID): Keyboard, Mouse, Generic
Communication Class (CDC)
Mass Storage Class (MSC)
Musical Instrument Digital Interface (MIDI)

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 support 1 level of hub (due to my laziness)

OS Abtraction layer

Currently the following OS are supported with tinyusb out of the box with a simple change of CFG_TUSB_OS macro.

No OS
FreeRTOS
MyNewt (work in progress)

Supported MCUs

The stack supports the following MCUs

Nordic: nRF52840
NXP: LPC11Uxx, LPC13xx, LPC175x_6x, LPC177x_8x, LPC18xx, LPC40xx, LPC43xx
MicroChip: SAMD21, SAMD51
ST: STM32F4

Here is the list of supported Boards

Compiler & IDE

The stack is developed with GCC compiler, and should be compilable with others. Folder examples provide Makefile and Segger Embedded Studio build support.

Getting Started

Here is the details for getting started with the stack.

Uses

TinyUSB is currently used by these other projects:

Porting
