自己写的 STM32 串口UART驱动, 不用固件库。超级终端界面按键时,自动回送。 应用范围: 因为不涉及IO口,所以此工程在STM32F1xx的任何主板上都可以运行。 编译器: IAR ARM 4.42A。 作者: w123456xy@sohu.com 15189792379。 -Write your own STM32 serial UART driver, no firmware library. HyperTerminal interface button, automatically send back. Application scope: because they do not involve IO port, so this works on any STM32F1xx motherboard can run. Compiler: IAR ARM 4.42A.
