使用stm32f103c8t6 输出pwm，可实现正弦波，三角波，锯齿波。(use stm32f103c8t6 to make pwm.)

ucOS+ucGUI 人机界面实验源码,采用STM32单片机(ucOS+ucGUI project source code)

2410开发板上键盘与LED的驱动实验，采用ZLG7290芯片(2410 development board keyboard and LED Drivers experiments using ZLG7290 Chip)

说明：  这段程序是用在一款七彩灯红外遥控解码程序里,单片机使用PIC12F629,软件模拟三路PWM输出驱动红绿蓝LED分八组共24个LED,实现单LED渐明渐暗,两LED一明一暗,七彩等九种花样.有断电记忆功能(This procedure is used in a colorful light infrared remote control decoding procedure, the single-chip using the PIC12F629, the software simulation of three-way PWM RGB LED output driver in eight groups of 24 LED, single LED gradually dimming out, two LED Kazuaki a dark, colorful patterns, such as nine. have power memory function)

This is my ECG signals data.
