使用定时器T0完成1秒和500毫秒方波的输出，用LED灯验证。 使用查询和中断方式实现。 -Use timers T0 seconds and 500 milliseconds to complete one square wave output with LED lights verify. Query and interrupt implementation.

基于DE0开发板的MPU6050数据采集，同时使用定时器，同时每一毫秒从串口发送数据，包含Quartus硬件电路部分-DE0 based development board MPU6050 data collection, using a timer, but every millisecond to send data from the serial port, including hardware circuit part Quartus
