“As a feather ESP32 newbie, after a bit of guessing around installation, proving blink_test worked and then adding a mini Adafruit item 4383 1.24" TFT display and running a system graphics test, was happy to start with luxury lithium battery charger project, reporting voltage details on pc screen using serial monitor. Extra luxury will be when I've figured out how to do same thru Bluetooth and WiFi (project in progress). Intend to add discharge circuit to to enable "condition of battery" reporting after full charge and discharge. Fascinating to see charge curve during "woken up" lithium cell during and after over-discharge (fire precautions taken...)”
