这是一个4*4键盘程序,已通过串口检测,效果还不错，给需要的朋友的一个参考。...

这是一个制作ICD2的程序，直接写入单片机即可使用-This is a production of ICD2 procedures, write directly to the use of single-chip microcomputer

该程序为基于51单片机的接口和片外应用的代码，在设计51单片机时可供参考，代码包括RS232通信、I2C、SPI、单总线、CAN总线、键盘、LED、LCD、AD/DA等应用。各工程在Keil调试通过，喜欢的朋友可供参考。-The program is based on the 51-chip microcontroller interface and application code, in the design of microcontroller 51 when the reference code, including RS232 communication, I2C, SPI, single-bus, CAN bus, keyboard, LED, LCD , AD/DA applications. Keil debugging the project passed, like a friend for reference.
