ssd1289-3.2的基于STM32的测试程序。(ssd1289-3.2 testing procedures based on the STM32 )

红外遥控代码，使用于51单片机。代码简单，功能强大。(Infrared remote control code, used in 51 single-chip microcomputer. The code simple, powerful. )

本程序能够实现广告灯的往正反方向来回移动。(Procedures to achieve the advertising lights move back and forth to the positive and negative direction.)

基于430的DC_DC变化，采用PID控制，调节PWM的输出占公比，从而反馈调节输出电压(Based on 430 DC_DC change, using PID control, adjust the PWM output accounted common ratio, thus regulating the output voltage feedback)

利用ULN2003A进行驱动，产生PWM波，里边有照片，可供参考，通过本例程了解PWM 的基本原理和使用 (#include <reg52.h> unsigned char timer1 sbit PWM=P1^2 void system_Ini() { TMOD|= 0x11 //PWM TH1 = 0xfe //11.0592 TL1 = 0x33 TR1 = 1 IE =0x8A } main() { system_Ini() while(1) { if(timer1>100) timer1=0 if(timer1<30) PWM=0 else PWM=1 } )

生成PWM波的c程序，需要的可以自己下载查看(A C program for generating PWM waves)

说明：  时钟芯片PCF8563 C51程序，本人测试通过(Clock chip PCF8563 C51 program, I test through)

This is a generic FIFO buffer that can be used to store any kind of items. It is written in C language and can be compiled and used on almost any architecture. It was designed to be used on memory limited architectures such as microcontrollers. Examples of the applications that can be built with this library include:
