microchip公司的32位MCU上开发的计算器，用4×4矩阵键盘实现了数字的输入，1608实现了输入与结果的显示-Using 32 bit pic produced by microchip,can type in the data using a 4*4 keyboard,a 1608 was used to show the data which was put in and the result

键盘任务与显示任务联合实验程序，：在实验中，利用五条短消息来完成键盘任务和显示任务之间的通信。程序中用两个按键分别控制数字窗口是否需要显示出来，用两个按键对数字窗口的水平位置进行调整，用10个按键分别输入10个数字，这些数字显示在窗口中。- Keyboard and display tasks experimental procedures, in experiments using five short message communication between the keyboard to
