PC run serial master serial debugging software to send data to the development board through the USB interface, the development board to receive the data frame, which is composed of the infrared port development board; such as receiving the infrared signal, when the infrared port receives the complete data frame, data from the USB port development board will be sent to PC. This program does not use NEC or Philips infrared protocol. It aims to show a way of using infrared interface just like using serial port. The experiment shows that this method is very effective, and still has very good receiving and sending effect under the condition of 1200BPS and 3 meters distance.
