# libcurl2rtt
The curl library ported on the RT-Thread platform. | 基于 RT-Thread 移植的 curl 库. 

注意测试的命令行的时候，需要讲shell线程的栈空间改大，否则系统线程会写穿，导致进入HF

RT-Thread is an open source IoT operating system from China, which has strong scalability: from a tiny kernel running on a tiny core, for example ARM Cortex-M0, or Cortex-M3/4/7, to a rich feature system running on MIPS32, ARM Cortex-A8, ARM Cortex-A9 DualCore etc.
