GPIO7 on CubeCell #7

Closed Skipper-is closed 5 years ago

Skipper-is commented 5 years ago

GPIO7, on the pinout says that it is battery test control. Is this capable of giving a reading on the battery level? Or is it for testing whether it is running on battery power?

GPIO7 is ADC enabler, before measure the battery voltage, need set GPIO7 LOW firstly.

You can refer to this example: https://github.com/HelTecAutomation/ASR650x-Arduino/blob/master/libraries/Basics/examples/ADC_battery/ADC_battery.ino

Hi, page not found, I also trying to understand how to connect battery to ADC (pullups or something) and also how to use GPIO7, currently its my interrupt pin, can I use other pins for interrupts? Thanks
