在keil上进行单片机语言编程，很实用的小例(Microcontroller programming language on the keil, very practical small cases )

同时使用STM32三个串口的接收与发送，串口1使用printf(),串口2使用u2_printf(),串口3使用u3_printf().接受采用定时器中断超时，5ms未接收到数据认为本次接收结束，置位相应的标志位，主程序检测并处理接收数据。(STM32 simultaneously receive and send three serial, serial port 1 to use printf (), 2 serial ports use u2_printf (), 3 serial ports use u3_printf (). Accepting timer interruption timeout, 5ms does not receive data that the receiving end of this, set the appropriate flag, the main program to detect and process the received data.)

Interactive interfaces are more and more integrated into many applications such as medical devices, process control, mobile phones and other hand-held devices. These interfaces are based mainly on graphic HMIs (human machine interface) using color LCDs. Worldwide, the desire for color support is growing dramatically. The purpose of this application note is to address this aspect by describing how to use the STM32F10xxx FSMC (flexible static memory controller) to drive a TFT color LCD. This document first describes how to connect a color LCD to the FSMC, then it provides a TFT LCD interfacing example. The demonstration firmware delivered with this application note, the STM32F10xxx firmware library, and other such firmware are available for download the STMicroelectronics website: www.st.com.

说明：  基于正点原子stm32精英开发板和openmv通讯，含openmv端配置，通过openmv（usart3）输出端连接到开发板（usart1）接收端，再由开发板（usart1）输出端输出到电脑，可以用xcom看到(Based on the communication between STM32 elite development board and openmv, including the configuration of openmv terminal, it is connected to the receiving end of development board (usart1) through the output end of openmv (usart3), and then output to the computer by the output end of usart1, which can be seen by XCOM)
