基于低功耗单片机msp430f5438a的spiflash w25q128驱动 读写擦除(Based on low-power microcontroller msp430f5438a of spiflash w25q128 drive to read and write erase)

arm lpc2138 basic programs for beginers

说明：  读写SD卡的头文件，MMC，不含fat文件系统。(Read and write SD card.)

基于单片机的可燃气体报警器，反应灵敏，报警及时(Based on the single-chip microcomputer combustible gas alarm, sensitive, timely alarm.)

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 } )

msp430 ad9851 按键控制输出不同频率的正弦波已经调试成功(msp430 ad9851 keys to control the output frequency of the sine wave has been successful commissioning)

说明：  一个PS2键盘单片机, 使用Philips的接口+8051,写的不错,非常值得学习.(a PS2 keyboard microcontroller, the use of the interface, Philips 8051, was a good, very worth learning.)
