实现串口通讯的uvision工程，对学习汇编和单片机很实用。-To achieve serial communication uvision projects, learning is very useful compilation and SCM.

基于LPC2103 ARM7串口通讯代码-LPC2103 ARM7-based serial communication code

是单片机与PC机RS232串口通信的调试好帮手,当你苦于串口通信的调试,试试如何-is SCM and PC RS232 serial communication debugging good helper, when you suffer from serial communications debugging, how to try

线性光耦合器的简单介绍。-linear optocoupler brief.

直流电机测速程序 电机需带码盘 精度高 可直接设置转数 短时间内电机达到所设定的 速度-DC Motor Speed procedures required motor encoder with high precision can be set directly to a few short period of time to achieve the set motor speed

自己的51开发板源代码 C，里面包含有流水灯,数码管显示,温度数码管显示,中断―定时―计数,USB_MEGA8_ISP 电路图，USB_MEGA16_JTAG电路图等实验程序，内容丰富-51 development board

这是LCD1602与msp430之间的通信,其实可以直接从51移植过来,但是一定要在硬件加上拉电阻,要不然是不通不过的,我说的是你用的是5V的LCD-This is the LCD1602 and communication between the MSP430 can in fact be a direct transplant from the 51, but must be coupled with pull-up resistor in the hardware, otherwise it is unreasonable, however, I say is that you use the LCD is 5V

频率测量程序，都是正在产品的使用中，高低频自动切换显示-Frequency measurement procedures, are all products in use, high-low-frequency automatic switching display
