基于c51环境，无数字时钟，游侠灯，爆闪灯三种模式。上一个没传成功，再试一次(C51-based environment, no digital clock, Ranger lights, Strobe three modes.)

单片机用作通用红外遥控接收器的设计 PWM调制开关电源的研究 以电子电力学为核心 以整流技术为主(generic microcontroller for infrared remote control receiver design PWM switching power supply of electronic learning for power to the core technology-based rectifier)

说明：  cordic算法的C语言实现，包含了相应C语言程序，十分珍贵(cordic algorithm C language, contains the corresponding C language procedure is very valuable)

里面含有一些STC12系列单片机常用的硬件驱动程序和片上资源驱动程序。工作在11.0592MHZ可以直接使用。如12864的串口方式驱动，1602驱动，18B20驱动，DHT11驱动，STC片上EEPROM/ADC/PWM等驱动程序，还包括一些经过本人用示波器侧过的STC12系列单片机在11.0592MHZ下的软件延时子函数。这些东西对你平时开发会大有帮助。(failed to translate)

使用DS18b20温度传感器采集温度的数据，感兴趣的可以尝试一下啊(Using DS18b20 temperature sensor to collect temperature data, interested can try it.)

OBD系统开发时OBD故障码解析，含大部分整车生产企业自定义的代码以及通用代码(OBD fault code parsing during the development of OBD system, including custom codes and general codes of most vehicle manufacturers)
