| Abstract: | Serial interface is one of the major communication interfaces between MCU and peripheral equipment. Serial communication plays a very important role in the data transmission. According to the frame format of the signals from MCU serial interface, the communication scheme which can directly modulate/demodulate the signals from MCU serial interface has been designed and implemented. The principles of modulation and demodulation circuit are analyzed in detail. The method of determining the circuit parameters is introduced, and its correctness has been proved by experiment. |
