stm32控制NRF905程序，现场运行验证2年。(stm32 NRF905 control procedures, on-site verification for 2 years running.)

本文介绍了一种基于51单片机的小车寻迹系统。该系统采用两组高灵敏度的光电对管，对路面黑色轨迹进行检测，并利用单片机产生PWM波，控制小车速度。测试结果表明，该系统能够平稳跟踪给定的路径。(This article describes a 51 MCU-based car tracking system. The system uses two sets of high sensitivity photoelectric tube, on road black track detection, and the use of single-chip PWM wave to control the car speed. The test results show that the system can have a smooth track the given path.)

AD0809+LCD1602+STC89C52+无源蜂鸣器报警，可显示酒精浓度，并且可以设置浓度值（加、减） 基于MQ-3酒精浓度传感器的酒精浓度测试仪(AD0809+ LCD1602+ STC89C52+ passive buzzer alarm can be displayed alcohol concentration, and can be set concentration value (addition, subtraction) MQ-3 alcohol concentration sensor-based alcohol concentration tester)

测试STM8S103F3的IO模拟I2C控制wm音频codec。调试通过(Testing STM8S103F3 to MockI2C control wm audio codec )
