UART CRC with MODBUS-RTU
I implemented on Psoc3 a signal conditioning with a Modbus-RTU interface (it's works well since 1 year). The CRC is checked by software. I would like to upgrade this application and to generate the CRC by hardware instead of software but I don't succed it, the CRC is always wrong. I just made this little test (enclose) to check the CRC...If someone has already implemented the same interface(Modbus-RTU with hardware CRC)??
