this is a digital Oscilloscope that build by me

说明：  串口控制c源代码，自己看看，根据例程改的(Serial port control C source code)

51 单片机 报警器 蜂鸣器实现 51 单片机 报警器 蜂鸣器实现(51 single alarm buzzer alarm buzzer achieving 51 SCM to achieve)

用51单片机实现PS2协议键盘，内有源码和PRETUS仿真(a ps2 keyborad code based on 51 CPU)

说明：  一个很通用的按键扫描程序，可用于单片机控制中(A very common key scanner can be used in the SCM)

八个发光二极管L1－L8分别接在单片机的P1.0－P1.7接口上，输出“0”时，发光二极管亮，开始时P1.0→P1.1→P1.2→P1.3→┅→P1.7→P1.6→┅→P1.0亮，重复循环。 (Eight light-emitting diodes L1-L8, respectively, then in the P1.0-P1.7 microcontroller interface, the output " 0" when the bright light-emitting diode, the beginning of P1.0 → P1.1 → P1.2 → P1. 3 → ┅ → P1.7 → P1.6 → ┅ → P1.0 Liang, repeat the cycle.)

加速度传感器很好用的，，可以移植的，你可以学习下，写的也不容易呢(Using an acceleration sensor,, you can refer to him,, a good, satisfying transplant)

//实验板的AVR程序，uart应用，和计算机通讯，回送PC发送的数据 //接线定义：PD0-RXD PD1-TXD 开关位置：SW6-7/8打开。 //使用串口调试器，使用十六进制方式，首先让PC发送一个字符给MCU，然后将接收到MCU返回的值。 //记事：本程序旨在对uart的理解与演示，程序适合初学者使用. //使用片外8MHz晶体，9600bps波特率(//Experimental board AVR procedures, uart applications, and computer communications, PC loopback send data// connection definition: PD0-RXD PD1-TXD switch location: SW6-7/8 open.// Use the serial port debugger, use the hexadecimal mode, let PC send a character to the MCU, and then will receive the MCU to return value.// Note: This program seeks to UART understanding and demonstration of procedures suitable for beginners to use.// Use the chip 8MHz crystal, 9600bps baud rate)

Empty activity, not needed for this test.

基于51单片机的eeprom程序，可以实现字节的读写等操作(51 microcontroller based on the EEPROM program, can achieve a byte read and write operation)
