CRICKIT on-board NeoPixel is not responding

Post by edgjr »

I'm assuming that the CRICKIT on-board "status" NeoPixel (not the NeoPixel port) is supposed to be accessible (according to the Python code), but I can't get it even turn on (and, if I remember correctly, it used to initialize to "green", but now stays dark). Have I somehow managed to kill part of my board?

On most Adafruit products board.NEOPIXEL is an alias the onboard NeoPixel. In the case of the crickit hat for Raspberry Pi it is crickit.neopixel.

Code: Select all

from adafruit_crickit import crickit

# Strip or ring of 8 NeoPixels
crickit.init_neopixel(8)
https://github.com/adafruit/Adafruit_Ci ... pletest.py

Is the Crickit slide switch set to on?

What are you powering it with?
You MUST provide about 4-5 Volts DC power to the Crickit to power the servos, motors, solenoids, NeoPixels, etc.
You CANNOT provide this power by plugging the Crickit, micro:bit, Feather, Raspberry Pi or Circuit Playground into USB. Computer USB ports cannot provide the 2 Amp + required to drive robotics, LEDs, speakers...
You can try to update your Crickit FW if you think something is off.

Thanks for the reply, mikeysklar - this is the status neopixel on the RaspberryPi Hat, which according to the CRICKIT code is

Code: Select all

crickit.onboard_pixel
of class NeoPixel (singlular).

It was functioning, but stopped after being moved to another Pi. I've got a 5v/2A power supply - the signal ports and capacitive touchpads are functioning (haven't gotten around to verifying the rest of the board). Unfortunately, re-applying the firmware did not change anything.

Oh, Friendly Support Folks! I think my CRICKIT Hat (PID 3957), order #2998142-2001053991 is not functioning correctly. I've re-flashed it several times, but this is the current observed state:

Signal Ports - all function for INPUT_PULLDOWN, INPUT (analog) and OUTPUT
TouchPad - all capactive functions work
Servo Ports - 1 thru 3 do not work, 4 does
Status NeoPixel - permanently off

I'm using the CircuitPython libraries (latest versions via pip3) - are there any board-level diagnostics I can run to determine if there's an actual issue (beyond the above)?

It is odd that we are not agreeing on the NeoPixel naming convention. The current docs are clear it is Crickit.neopixel.

https://docs.circuitpython.org/projects ... en/latest/

Where are you finding onboard_pixel? I'm wondering if you are using crickit instructions that are out of date or for another model?

What was the purchase date of the board?

Purchase date was this January, so it's a brand-new board.

The adafruit_crickit.py code indicates two neopixels - the one I'm referring to is at https://github.com/adafruit/Adafruit_Ci ... it.py#L370

More info - not only is that indicator dark, but the LED for the USB port didn't react at all when I plugged in a USB cable to re-apply the SeeSaw firmware (I just remembered not seeing it on the last refresh - which was prior to my last post).

Here's specifically what I'm talking about (hope this helps)

I checked out some other things on the board and it actually looks like I've fried it - I believe I accidentally gave it 9v at one point early on.

Time for a new one... Thanks for the inputs.

Don't know if anyone is paying attention to this particular topic, or if this additional information is even useful...

Just for grins, I tried plugging in the Pi power separately from the CRICKITHat and the status LED came on again - but it was so bright I had to put my finger over it just to take a picture!

Wonder what one does with a 1/3 dead hat...
