改程序详细介绍了如何使用TMS320F2812通过GPIO对LED灯进行控制，可以说实现LED亮灭，循环点亮，循环流水灯。-The program introduces how to use TMS320F2812 through GPIO control of LED lights, can say realize kill bright light, LED lamp, circulation water cycle.

该程序为TMS320F2812的中断程序，每次中断服务程序中，修改GPIO的输出值，实现与其相连的LED数量显示发生变化-The program for TMS320F2812 interrupt routine, every time the interrupt service routine, modify GPIO output values, realize the number connected to it that LED change
