向单片机发送数据后 可以点亮灯 借此程序可以学习串口的使用 发送1 点亮P1^1 以此类推 单片机菜鸟学必备！！用Keil软件编译出hex文件再烧写就可以了。-After sending data to the microcontroller can point lighting program can learn to use the serial port to send a light P1 ^ 1 and so must learn microcontroller rookie! ! Compile with Keil software hex file can be re-programmed.
