*红外测试程序，用单片机通过发射管发射38K的调制频率码，由一体化接收并解码由发光管显示。

*正常情况下，由于反射和高灵敏度接收，LED4（P1.3)一直闪烁，可以用黑色纸片完全遮挡接收头使

                * Under normal circumstances, due to reflection and high-sensitivity receiver, LED4 (P1.3) has been flashing, can completely block the receiving head with a black piece of paper

                * Can not receive a signal to the launch tube, which is LED4 off. The normal of the functional
