2052Player
说明： 由于不满意语音芯片的复制性差，于是自己做了一个语言模块，用STC12LE2052单片机的PWM功能播放声音，从Wave文件中提取的声音数据通过串口从计算机下载，存储在串行Flash芯片SST25VF016B中，可进行单段播放和循环播放，单个模块的制作成本应该在30元以下，可以播8K8位的声音256秒。(Not satisfied with the voice chip, as a result of poor copy, so do a language module, with the STC' s 2052 single-chip PWM function to play a sound, from the Wave files to extract the audio data downloaded from the computer through the serial port, is stored in the Serial Flash chip, can play single player and recycling, the production costs of a single module should be below 30, you can broadcast the voice of 8K8-bit 256 seconds.)

UART
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.)
