Hi all, new to this forum. Using a Teensy 4, I had a 64x64 from Adafruit that worked like a charm, now trying with a larger display I got from AliExpress. Its 160x80 2mm. I have tried all the kPanelTypes from 0-16 with no luck. Is there anything special that needs to be done with it? I actually have no clue what chipset it is, i dont really see any identifying info on the back.
Thanks for your help.
Please read a model of LED drivers - a text on URxx UGxx UBxx chips
Sorry, SmartMatrix Library only supports panels that are a power of 2 in height, eg 16/32/64/128. Beyond that, I’m guessing these panels use a chipset that isn’t supported. These 160x80 and similar panels weren’t around when the library was made and I have no plans to add support.
I’m adding a note to the wiki to help others avoid these.
Hi, Louis
If the driver chip is from the supported ones, such panels has nothing different from the standard. The only thing that have to be taking in account is the using of shift register multiplexor type, because the traditional line switchers can address up to 32 lines.
Beside of this, this panel should works with the library without changing the code.
That’s good to know. I recall seeing at least one post from someone troubleshooting these panels but not any success stories. If anyone posts that they got one to work I’ll update the wiki with a link to the post
