ILI9341 Display looking strange after a few minutes


does someone have an idea why my display looks all screwed up?

It’s all fine and dandy at first:

But after a few minutes the colours go funny and the text goes all over the place.

Have you seen something like this?


@volker, you could be sending data too fast for the display so check your SPI settings. How long are the wires between the Particle device and the display? Are you using a specific library to drive the display?

The cables are 8 inch / 20cm.

I have followed your advice and checked the cable connections.

I disconnected everything and re-connected.
Now the problem disappeared. It seems that there were connection issues. Thanks,
