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 } )

STM32L152VB的AD采集程序，7通道DMA方式采集，通过串口发送到PC，本人查阅多方资料亲自编程测试，可直接用。附带STM32L152VB工程模板，本人根据资料自己建的。(The AD STM32L152VB acquisition program, 7 channel DMA acquisition, through the serial port to send to the PC multi access information, I personally programming test, can be directly used. With STM32L152VB project templates according to the data, I built myself. )
