I want to add voltage monitoring on my older board, so I made a voltage divider 33k/10k and connect it to pin 19 of the MCU 328p. I have checked my connections and all is ok but I can't have access to the "Battery Monitoring" GUI tab.
Thank for your answer Garug, I had desolder the pin 19 before to solder the voltage divider on it but same result, the "Battery monitoring" part in GUI is grey...
