Takes about 2 minutes. Do not unplug the cable until it says the update is complete.

Before you click Install
  1. Use a Windows or Mac computer with Chrome or Edge. A phone or iPad will not work.
  2. Plug the LCD-MIDI into the computer with a USB-C data cable (not a charge-only cable).
  3. Close the Arduino IDE or any other serial program if one is open.
  4. Click Install, pick the device in the list (CP2102, CH340 or USB Serial), then click Install again.
  5. When it says complete, unplug the USB cable and plug it back in. The new Rev number shows on the LCD-MIDI home screen.

Windows: if no device shows in the list, the CH340 USB driver may need to be installed.
