CH554MCU_USB通讯例程

C语言实现带通滤波器功能，比matlab更加试用可用于单片机开发(FIR band_pass filter )

说明：  adc采样再通过液晶屏显示111111111111(adc sampling and then displayed via LCD 11111111111)

TM4C123单片机 SPWM模块使用，含主程序与库(TM4C123 SPWMmodule with main function)

基本51单片机制作的电视机遥控器，24M的晶振，并且已经通过实验，可以成功遥控。工作原理： 由另一遥控器发射出来的红外进行解码，并且经单片机识别后，发射电视遥控器相应的功能键代码。(51 Microcontroller basic TV remote, 24M crystal, and has been through experiments, can successfully remote control. How it works: emitted by another infrared remote control decoding and identification by the MCU after the launch of the corresponding function key remote control code.)

通过51单片机设计一个电子时钟，精确到秒，可以通过按键调节时间(By 51 microcontroller design an electronic clock, accurate to seconds, you can adjust the time by pressing a button)

dm8203的网口原理图，很有用的，适合初学者使用(dm8203 for net port sch，very important)

直流发电机的调速程序，使用的是STC12C5A的单片机，采用PWM技术来调节他的速度，简单便捷。(DC generator speed control program use is microcontroller of STC12C5A, and PWM technology to adjust his speed, simple and convenient.)

说明：  两路光电开关驱动，2019电赛A组，测试程序(Two-way Photoelectric Switch Drive, Group A of 2019 Electricity Competition, Test Procedure)

说明：  助力车仪表程序 ,彩屏 TFT 电动车仪表(penda bike meter for bafang motor)

OS_II移植到单片机,网上都是大模式移植,这是我在网站上找到的小模式移植,不知道有用吗?(OS_II transplanted into single-chip, on-line model of graft are large, this is my website found in the small model of transplantation, I do not know useful?)
