Hello I am using a raspberry pi 3b+ and 32x64 led matrix from adafruit. But whenever I run my code my matrix does not light up. Please help, I am new and don’t know what I’m doing.
A clear photo of the rear side of the matrix may helps.
Also please lookup a chips on the panel and write the indexes to the forum.
it’s really hard to read the command lines you used, please try to paste the command line text here, please
This is a Linux kernel boot parameter. The Raspberry Pi has a multi-core processor. The isolcpus parameter is used to “isolate” a specific CPU core
The suggestion in the command line “to slightly improve display update, add isolcpus=3 at the end of /boot/cmdline.txt and reboot “
There should be instructions online on how to edit that text file.
