PC机与RS232串口实验，实现51单片机通过串口进行数据的收发.-PC, and RS232 serial experiments, to achieve 51 microcontroller through the serial port to send and receive data.

胡家荣（hjr7581@163.com）用KEIL写的的几个LCD、串口等方面的程序-Hu Jia-rong (hjr7581@163.com) with KEIL wrote several LCD, Serial procedures etc.

具体的硬件结构,大家可以看 WS 系列产品的原理图 * 利用AT89S51单片机来制作一个手动计数器，在AT89S51单片机的P3.3管脚接一个轻触开关， * 作为手动计数的按钮. 数码管驱动采用动态扫描方式用单片机的P0.0－P0.7驱动数码管的段码， * P1.3 控制个位数码管的共阳极公共端，P1.2 控制十位数码管的共阳极公共端 * 通过按一下P3.3按键,数码管做 1 的累加, 实现00~99的计数功能,当计到99时又从00开始. * 大家可自行修改程序,扩展到0000~9999的计数范围-Specific hardware architecture, we can look WS schematic family of products using AT89S51* Single-chip to produce a manual counter, in the P3.3 pin MCU AT89S51 by one touch switch,* as a manual count of button. nixie tube driven by dynamic scanning with MCU P0.0-P0.7 driver code segment digital tube,* P1.3 control bit digital tube anode of a total public client, P1.2 control of 10 digital total anode tube through public client* P3.3 click buttons, a digital pipe to do one of the cumulative, realize 00 ~ 99 count function, when the total to 99 from 00 the beginning of time.* everyone can modify the program, extended to 0000 range of ~ 9999 count

当前LCM的主流接口有并口和串口。并口引脚多，产生串扰，串口则没有诸如此类的缺点。SPI作为串口家族的一员，具有高速同步、芯片管脚少和信号稳定不产生串扰等优点，越来越受到开发人员的青睐。但是，具有SPI的LCM并不是毫无缺点的，市场上以COG(chip on glass)方式封装的LCM大都是基于单工方式传输的，这将给开发带来了非常大的麻烦。本文主要论述基于单工SPI的GUI开发方案，详细地分析了基于单工SPI的GUI的开发开台，论述并分析在GUI开发过程中遇到的问题，最后提出增加虚拟LCD的方案解决这个问题。-err
