LILYGO TTGO T5 2.66 inch E-paper device

The device does not turn on (device leds stay dark) when connected to my computer.

1. Check you have a USB to TTL (T-U2T) connector connected between the device and your USB cable.
2. Check the device is not faulty by connecting it to a power supply, instead of the computer. The red power led should light up.

Building From Source

MacOS iCloud and Arduino library conflicts

One solution is wait until all folders and files have synchronised with iCloud before building.
