Raspberry Pi 5 with 7c81 WORKING!

Category: Driver Boards

Thanks to the wonderful efforts of everyone recently, I have been able to get my 7c81 working excellently with my Raspberry Pi 5 on the 2.10.0~pre0 (self built) version using the `hm2_spix` driver.

I have a lot of configuration and testing to do, but thus far it seems to be working flawlessly. 

I did have a few things to get it working the way I wanted, one was getting remote access and spi working for flashing:
/boot/broadcom/config.txt

...
dtparam=spi=on
...
dtoverlay=vc4-kms-v3d-pi5


I also had to replace the hm2 module load with the spix version in the `foo.hal` file.


loadrt hm2_spix config="firmware=hm2/7c81/G540X2.BIT num_encoders=0 num_pwmgens=0 num_stepgens=4"


Ignore the mess of wires, I need to get some mounting stuff figured out, plus all of the plasma cutting controls and so on figured out next too.

Hallo,

schön, dass du die Frustrationsschwelle "verschoben hast" :-)
Ich vestehe nicht ganz, was du verändern möchtest. X-geht ja "eigenlich" immer von "links" nach "rechts" und y immer "vorne-hinten".
Soll die Beschriftung am Bildschirm getauscht werden?
Die Zuordnung der Antriebe könnte man ja einfach durch umstöpseln der Motoren erledigen, oder in der *.hal die zugehörigen Mesa-Ausgänge vertauschen.

Gruß Timo
