w90p710的LCD显示图片的程序，已测试(w90p710 the LCD display pictures of the process, have been tested)

很好用的音频测试程序，可用于普通制式的快速调试(Good audio test program can be used for ordinary standard fast debugging )

说明：  stm32板上的SD卡的使用，通过SPI接口控制SD卡，不涉及文件系统，只是简单的实现底层读写接口，编译环境为IAR。(stm32 board SD card, SD card through the SPI interface to control the file system does not involve simply the realization of the underlying reader interface, IAR compiler environment.)

自己试用过，适合初学，比较基础，但不是原创,请见谅，希望大家共同进步(I have tried it, suitable for beginners, comparatively basic, but not original, please forgive me, I hope you all make progress together.)

说明：  单片机驱动3310 lcd显示屏的c程序，单片机与屏的线路连接可以参见程序中的宏定义。程序写得很精简，但是很好用。(Microprocessor 3310 LCD display c procedures, SCM and the screen can see the line connecting the procedures macro definition. Very streamlined procedures, but is useful.)

example for use ADC8535 - adc convertor

说明：  ec20通信基于stm32单片机，MQTT协议连接移动的onenet平台。(EC20 communication is based on STM32 single chip microcomputer, mqtt protocol connects the mobile onenet platform.)

笔记本键盘测试程序，可以测试键盘按键是否有作用。(Notebook keyboard test program.)
