I’m building a software where I have an RC522 RFID reader connected to the GPIO of the rapberry pi and 2 relays (one is a latching relay) connected on the Grove Pi+. There is some communication bug. If I close the latching relay and then separately in another process uses the RC522 reader, it will somehow trigger the latching relay and open it. Is there a way to deactivate the connection to the GrovePi while I’m using the RC522 reader?
Thanks in advance,
