I received my Z-UNO board and shield and experimented with a URM07 ultra-sonic sensor. This sensor uses a serial communication. It works perfectly when connected to RX-TX directly on Z-UNO board but if I try to use it by connecting to the shield, it doesn’t work. I used the shield configurator and put the two jumpers on the shield as specified. But it doesn’t work.
Attached is the configuration I used.
Should I use Serial, Serial0 or Serial1 in the code?
Thanks for your help!
