Pi 4 raspberryjamma GPIO driver

Post by markus1979 » Wed Jan 22, 2020 4:42 am

Hi Dee2eR,
I've been using the modified version of mk_arcade_joytick_rpi for rjamma that you posted on the aussie arcade forum.
It installed and worked well on my old builds with a Pi 3.
Now that I'm trying to use it on a Buster build for the Pi 4 it won't build and install anymore.
Would you be able to release a new version of the rjamma mk_arcade_joystick_rpi that is compatable with a build of raspbian buster?

I read you've been working on a Pi 4 build of Arpicade, did you get the rjamma GPIO working and could you please release the driver if you did.

Any help would be much appreciated.

I only have it partially working at the moment, still yet to get the Pi4s internal pull-ups to work. It works fine with hardware pullups but I want to fix it rather than force people to install a bunch of extra resistors. I've also compiled but not tested the 4 player version, it will have the same issue.

The Pi4 version of ARpiCADE is shaping up but there's still no ETA for the release due to little issues like that.

It's not perfect, the pullups still don't work but I found a workaround for that so here it is: https://drive.google.com/open?id=1rSryI ... v8MMw5JAuI

you will need to add this line to /boot/config.txt to make the Pi4s internal pull-ups work:
gpio=2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27=pu
I've only tested it on Pi4.

Thank you very much. I'll test it tonight.
Looking forward to your Arpicade 4.0 beta. I would use the hd output anyway so will be perfect for my setup.
RaspberryJamma is an amazing product.
