这个程序是设计了一个LED圣诞树的作品。炫彩美观。(This program is designed to work with a LED Christmas tree. Bright and beautiful.)

-lpc2148 -sdcard -vms board

该源程序的功能是设计一个时钟，时钟精度还可以，这是单片机学习的一个进阶吧，掌握了它，也算是对单片机有比较熟练的应用了，加油(The source function is to design a clock, clock accuracy can be, this is an advanced single-chip learning it, grasp it, can be considered a relatively skilled microcontroller applications, the refueling)

stm8s003写的电压表程序，压缩包包含原理图与源代码，IAR环境编译(Stm8s003 write the voltmeter program, compressed package contains the schematic and source code, IAR environment compiler)

STM32单片机 串口bootloader ，IAP源码。测试过了。方便调试使用。方便商用升级代码，串口实现，方便改成USB接口(STM3210X uart bootloader IAP)

Keil C Cortex m3 programming SD card

基于c8051f单片机的内部模数转换模块程序，已封装，可以直接移植。。。(Based on the single chip microcomputer c8051f internal digital-to-analog conversion module program, already enclosed, can directly transplant...)

STM32F103 UART配置，实现C语言printf功能(STM32F103 UART configuration, implement the C language printf function)

说明：  spi模拟i2s，实现音频播放，网上的参考，不易找到，供大家分享(spi simulation i2s, for audio playback, online reference, easy to find for people to share)

PT2258源代码,音频处理系统，高低音及输入切换(PT2258 source code, audio processing system, high and low, and input switching)
