基于单片机与ch451的键盘扫描与显示程序-Based on SCM and ch451 keyboard scanning and display program

CH451键盘管理及LED显示芯片的C程序，调试通过MCU为LPC2103-CH451 keyboard management and LED display chip C program debugging through the MCU for the LPC2103

CH5451驱动键盘的程序，使用atmega16作为控制器，用lcd12864做显示。-CH5451 keyboard driver program, use atmega16 as the controller to do with lcd12864 display.

基于CH451的键盘扫描程序设计采用AVR单片机ATmega16进行读取CH451的接收到的按键值，CH451可以实现8*8矩阵键盘输入，且带有中断提醒，接收到的按键值在12864液晶上显示。程序中采用的是2*3矩阵。系统采用AVR Studio+WinAVR构成的AVR GCC编译环境。-CH451 based keyboard scanner design uses AVR microcontroller ATmega16 reads received the key value CH451
