Raspberry Pi4 - HDMI option? #11

Open britxpatusa opened 3 years ago

britxpatusa commented 3 years ago

Hello, Is there a way to specify a HDMI port? i would like to display what is on the second HDMI port without a monitor attached?

Hey did you get this Library working? I use a Pi 4 too... but if I start the display-test nothing happens on my panel. The example and own programs do pretty well.

Did either of you get this library working on Raspberry Pi 4? I'm looking to buy these panels for my Pi 4, but I am hesitant if this library doesn't work with it...

I'd love to get this working on newer hardware too. I was able to make it work on a Pi 3, but we have Pi 4 and now Pi 5. Also, the rpi-rgb-led-matrix libriaries have been updated to use at least pi 4 if not pi 5.

Greetings,

To have this working on RPi 4, you must install a Raspbian Buster version. I don't know if Raspbian NOW comes customized to a specific board, but I get working rpi-fb-matrix with Rpi 4, with buster, but I do some modifications to the rpi-rgb-led-matrix library to run with this, because the version forked only have few multiplexing support, and I have 32x16 1/4 scan panel that works with Multiplexing = 8.

It works, GREAT, but as well as rpi-rgb-led-matrix has no support for RPi 5, I'm wasn't enable to try on it; only tested in Rpi 3 B+ and Rpi 4
