内容： *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 *之不能接收到发射管的信号，这是LED4熄灭。说明功能性正常 -Content:* IR test program, launched with the microcontroller through the launch tube of the modulation frequency of 38K code, by the integration to receive and decode from the LED display.* Under normal circumstances, due to reflection and high-sensitivity receiver, LED4 (P1.3) has been flickering, you can completely block the black pieces of paper to make* that they are not receiving the first emission control signal is received, it is LED4 out. Note the normal functional
