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

基于stm32的12864液晶使用方程，可在12864液晶上显示任意字符，采用数组，ch451键盘，12864液晶(Based on stm32's 12864 liquid crystal use equation, it can display arbitrary characters on 12864 LCD, with array, ch451 keyboard and 12864 LCD)
