| Abstract: | A software principle and solution were proposed to realize the data's transfer coding and decoding with PIC SCM and wireless data transfer module in low speed wireless data transfer. Manchester code was used in data coding. Every data frame includes synchronization bit,inception bit,true data bit and CRC checking bit. The decoding process includes the capture of synchronization bit,decision of receiving data value and CRC checking. The test results show that such encoding/decoding method has stronger anti-interference ability and more flexible data format than the general method. |
