Itsy Bitsy m0 Express Maybe got a defective unit

Post by Daft_vagabond »

It was recommended that I bring up concerns about a defective unit here.

I received my order yesterday and started trying to use it today. At first, the default files kicked in and flashed the onboard neopixel a few different colors, but once I loaded my own files onto it, I couldn't get a response. After that I went through all the troubleshooting steps you might expect, firmware, drives, different USB cable, rebooting everything, ect. I still couldn't get me code to run, so, just in-case it was my code, I decided to try out some of the example codes from here on the website, still nothing. I just tried one last time to run one of the servo sweeping examples and I noticed little sparks coming form the USB pin and I had no choice but to quickly unplug it form my PC.

I'm not certain what to do. But I appreciate any help.

Are you using CircuitPython? If so, what are you naming the code files on the CIRCUITPY drive?

Sorry for the late replay, really. I didn't get an alert for some reason.

"main.py" is the name I'm using currently, though I've tried the other defaults.

That shoudl be cood. Just be sure that there is only one of main.py, main.txt, code.py, code.txt and maybe some others with a basename of main or code. It looks in a particular order and tries the first it finds.

Can you try a simple blink example?

Code: Select all

import board
import digitalio
import time

led = digitalio.DigitalInOut(board.LED)
led.direction = digitalio.Direction.OUTPUT

while True:
    led.value = True
    time.sleep(0.5)
    led.value = False
    time.sleep(0.5)

Sorry for the confusion. In the couple days that I didn't receive a notification, I decided to reach out with a more post that more elaborately described my situation.

Since then this issue has been resolved but I appreciate your assistance regardless, thank you.

Next time I'll be certain to check in more frequently and to be less reliant on automated notifications
