本程序是TI的32位单片机LM3S9D96官方开发板上、基于IAR平台的，用C语言编写的的一个设计AD、液晶显示、串口打印的完整工程文件。已经调通。原创的程序。对于掌握LM3S些列单片机的高级功能很有用。(This program is TI' s 32 the microcontroller LM3S9D96 official development board, IAR platform, written in C language design the AD LCD, serial print complete engineering documents. Has been transferred Qualcomm. Original program. Useful advanced features master LM3S these columns microcontroller.)

国内专业手机生产厂商PCBA验收检验标准！！！(Professional mobile phone manufacturer PCBA test)

For this project you need a 3.7v power supply that prepared by LM317 regulator. So you need MAX232 for connect uart to pc .my AVR chip project is Mega8 that you can program on any Avr chip have 2kbyte rom. In bascom spi hardware don’t work correct, so I have to software spi ,but the software spi configure have low speed into hardware spi.
