在STM32F103上实现双定时器1S定时，利用RS232串口发送数据，利用中断检测PS2键盘和PC机交换信息并在串口助手上显示-In the STM32F103 dual timer 1 S timing, using RS232 serial send data, using interrupt the PS2 and PC keyboard detection to exchange information and serial port on display in assistant

这是一个基于硬件平台s3c44B0和操作系统为ucos的ps2键盘的程序，可以移植到自己的系统中。-This is a hardware-based platform and operating system for uCOS S3C44B0 the ps2 keyboard procedures, can be transferred to your system.

可以实现PS2键盘 定时中断 UART串口通信-PS2 keyboard can be achieved timer interrupt UART serial communication
