Yes, sorry, maybe I wasn't really clear. So, my system has a computer, a Ccontrol and one RFID reader. The PC is connected via USB to the CControl and the RFID to the CControl via serial port (TTL). The problem we have is that, when using the commands 'put' or 'get' in the CControl, they are sent both to the computer and the RFID reader, and we don't know how to specify where do we want to send them. It would be easy with I2C but i don't know if there's possible to do any "addressing" with the serial port... I hope now I have been more clear. Thanks in advance!!
