利用stm32单片机，对I2C和串口通信做测试，通过LED灯来显示-The stm32 MCU, I2C and serial communication test, LED lights to display

FPGA串口通信能在实现字符数据传输，与stm32中的串口通信类似(FPGA serial communication, in the realization of character data transmission, and STM32 serial communication similar)

在STM32板子与电脑串口助手进行通信,用串口的DMA方式,先接收,再发送到PC端,可以连续接收,通过按键一次发送.(In the STM32 board and computer serial assistant for communication, using the serial port DMA way, first receive, and then sent to the PC terminal, you can receive continuously, sent through

迪文屏串口程序，自己写，可以移植,用于STM32F1xx系列ARM,可以方便移植使用。 (DWIN DGUS programm used to STM32F1xx.)((DWIN DGUS programm used to STM32F1xx.))
