232通信，我调试过，没有什么问题。情大家下载

里面有c和单片机的程序，可以找到延时，lcd显示，树脂转换，键盘扫描等-There are c and SCM procedures, can be found delay, lcd display, resin conversion, keyboard scanning, etc.

用C51和汇编混合实现4个软串口的程序，接口是C51的-Compilation mixed by C51 and realize four soft serial procedures, the interface is the C51

这个程序是用Intel8086平台运行的一个汇编语言程序，其中包含两首歌，可通过控制来实现音乐播放的功能，同时，也以实现按键控制8086发出声音的功能。

都是测试程序，也就是模型，比如电机，磁链模型，很实用-matlab

关于LCD液晶的开发应用等技术文章包括驱动程序，硬件开发等-LCD on the development and application of technical articles driver and hardware development

Matrix Operation in Assembly Language

本程序是利用文件240X.ASM中的子程序对EEPROM 240X进行多字节读写的操作示例(同样适用于416)-this procedure is to use the document 240X.ASM subroutine right EEPROM 240X multi-byte read and write operations examples (the same applies to 416)

用89C51串行口外接CD4094移位寄存器扩展8位并行口，8位并行口的每位都接一个发光二极管，要求发光二极管从左到右以一定延迟轮流显示，并不断循环。-Using 89C51 external serial port expansion CD4094 shift register 8-bit parallel port, 8-bit parallel port of each one, all light-emitting diodes, light emitting diodes require a certain delay in rotation from left to right shows, and continue the cycle.
