Circuit Playground Express all neopixels green

Post by wa9ecj »

When I connect to my mac the neopixels are all green and the #13 led pulses red continuously. When I connect it to a battery or wall charger, all the neopixels are red. Pressing the reset button does nothing to solve this problem. CPLAYBOOT shows up as a drive.

UF2 Bootloader v3.14.0 SFHWRO
Model: CPlay Express
Board-ID: SAMD21G18A-CPlay-v0

MacOS 12.4

OK. It's in bootloader mode. What happens if you install CircuitPython? Download the latest UF2 file from https://circuitpython.org/board/circuit ... d_express/ and copy it to CPLAYBOOT.
