MagTag display is broken

Post by serenaden »

Whatever I put on the MagTag, the display is at best showing some grey bands or some black dots. I have now installed the 'magtag_demoboot.bin' with esptool.py both nothing on the display. I also noted that button D12, 14, and 15 changed the color on the neopixels. However, button D11 did nothing.

Please post a photo of the back of the MagTag so we can look for any obvious hardware issues.

Also, one of the screen showing the display behavior would help.

And just to be sure - it's showing this behavior out of the box?

Attached are photos on the front and back of the MagTag.

Sometimes on the front I can see some black stripes in the lower right corner.

It's been like this from the very start. I have never succeeded in getting anything readable out of this display.

Thanks for the photos. That all generally looks OK. The ribbon cable on the display connector was the main thing of concern. But it looks well seated and both lock (black plastic tabs) are pushed in.

OK, just ran that demo to remind myself exactly what it does. The display should show MAGTAG in nice font and invert black/white color every now and then. NeoPixels should cycle through rainbow colors. Pressing D15 makes NeoPixels all red. Pressing D14 makes NeoPixels all green. Pressing D12 makes NeoPixels all blue. Pressing D11 plays little video game sound.

For the buttons that are working - are you seeing the above behavior at least?

What you see on the photo is what I get when running the demo. Sometimes there is a black stripe in the lower, right corner. Sometimes the display shows a black border. Nothing consistent except for the missing MagTag logo.

Button 1, 2, and 3 will change the color of the neopixels as described. Button 4 (D11) has no effect (no sound).

OK. Thanks for trying the demo. Weird issue as it seems like multiple things may be going on. And nothing obvious in your nice photos. Let's just replace it and see if that helps.

Send an email to [email protected] with a link to this thread and your order number and they can send you a replacement MagTag.
