51单片机控制NAND Flash读写程序,编译环境vc++，可根据flash不同做稍加修改,即可实现功能要求(51 single-chip NAND Flash read and write procedures, compile environmental vc++, according to flash a little modified)

基于MSP430的LCD1602驱动程序，该程序只用到了4根传输线，里面有写好了的h文件和c文件，添加到工程即可运用。(Based on LCD1602 MSP430 driver, the program only to 4 root transmission line, and there are written the h files and c file, adding to the engineering can be used.)

这是基于飞思卡尔十六位单片机的RS485通信的例程(freescale RS485 routine)

12864上面的并行画线，可以画圆，三角形，正方形，直线，正弦波(12,864 above the parallel line drawing, you can draw a circle, triangle, square, line, sine wave)
