`adafruit_boardtest.boardtest_led`
|
|
====================================================
|
|
Toggles all available onboard LEDs. You will need to manually verify their
|
|
operation by watching them.
|
|
|
|
Run this script as its own main.py to individually run the test, or compile
|
|
with mpy-cross and call from separate test script.
