matrix.update never returns or displays on Pi 4 #8

Hi! I put the sample code under "Get some fun" into a file, and invoked it with sudo node display.js. The call to matrix.update() never returns, and nothing is shown on the display. I'm using Node 10.16.2 under Raspbian Lite on a Raspberry Pi 4. For interfacing, I'm using one of hzeller's active 3-chain boards. The displays are 32x64 P3 panels, with the FM6126 chipset. Using hzeller's library directly works. Any thoughts?

Ok i found tour repo, you try to just write a file where you init the Matrix object and use update method. But probably the problem is the rasperry 4 because i'm not sure that it's supporter.

@ArcaneDiver Well, I was worried about that too, but as I said, the native library underlying node-rpi-rgb-led-matrix works, so I'm not thinking it's a PI4 issue. I will test with a Pi 3 though, just to make sure.

Welp, that's what I get for assuming. I moved the interface board over to a Pi 3 B+ and it works like a champ. Well, if there's anything I can do to help test on Pi 4, I've got three of 'em not doing anything :)

Yup we have not tested anything yet on any hardware but the pi 3B+ - if you want to debug on your own and find out what's not working feel free. We will eventually update it to work on the pi4 but it's not a priority at the moment.

It's possible you could pull this git-repo, update hzellers sub-repo to the newer one and rebuild to get it to work on rpi4. I've seen some discussion about the hardware on his repo.

We have just updated this to work on RPI4 ! test it if you can :)
