Add Voltage monitoring on older boards
  • Hello,

    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.

    Any ideas?

    Thanks in advance
  • I don't know why photos is not working but if you want see just click on them;D
  • I think you need to lift the pin 19 first. It might be grounded. You could these this measuring the voltage going to the pin 19.
  • 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...
