MODBUS RTU protocol instrument communication needs CRC verification, SCM can use this procedure to generate CRC checksum, the polynomial is 0xA001 The microcontroller used for the STC15 series microcontroller, but the CRC generation process is very simple, general 51 microcontroller can be generated
