基于tlc5615芯片的DAC源码，单片机类型为89s52。

LPC 1768  有个内部 ADC。 根据PCB 设计，它的输出包含噪音。 通过轮询 ADC 读取序列， 发现噪音输出在其他噪音输出后不会重复， 根据这个原理， 而不是读取操作， 可以进行 3 次重复读操作， 这样，其中一个样本会被删除， 其他样本的平均数是子程序的返回值

arm的C语言教程　无操作系统支持的嵌入式系统软件,包括系统引导(BOOT) 、驱动程序、动态内存管理、IPO、通信以及应用软件等方面。 本文详细介绍了嵌入式平台上用C 语言编写系统软件和应用软件的方法。虽然是针对ARM平台介绍的,但基本经验和算法也适 合于其他嵌入式平台的软件设计-arm of the C language tutorial without operating system support for embedded systems software, including system boot (BOOT), driver, dynamic memory management, IPO, communications and application software and so on. This paper describes the embedded platform using C language, system software and application software methods. Although introduced for the ARM platform, but the basic experience and the algorithm is also suitable for other embedded platforms, software design

1.此代码在SDT2.51下调试通过，可以在我的板子ARM DEVELOP BOARD V1.0上面跑！其上电以后LED会闪烁一下，接着串口0会输出一些系统信息 可以通过串口终端与系统交互，可以测试320X240 STN LCD,包括图形显示函数，ascii字符显示函数。-1. This code debugging under the SDT2.51 passed, in my plank ARM DEVELOP BOARD V1.0 above run! After its power LED flashes that went 0 serial output will be some system information through serial terminal and system interaction, can test 320x240 STN LCD, including graphics function, ascii character display function.
