Raspberry Pi5 #127

Closed ukscone closed 1 year ago

ukscone commented 1 year ago

I'm not sure if I can be of any use to you but I have a Raspberry Pi5 already in my hands as I was part of the test group for it. If you'd like any testing done on it i'm happy to help. I did try to get things running today from your github repo but i'm still a very newbie rust user so didn't get past the ''' Error: Io(Os { code: 2, kind: NotFound, message: "No such file or directory" }) ''' running the examples which i believe is an error on how i built the library rather than the library itself

Great to hear! I wasn't expecting any problems, but it's always good to check.

It looks like rppal is ready for the Pi 5. I'll get 0.15.0 out the door within the next day or two. Thanks again for all the help!

ukscone commented 1 year ago

great. i'm looking forward to the release as then i'll be able to try porting one of my last python programs left to rust (& tauri) Pity we don't seem to have a rust equivilent of the python module luma but we can't have everything :)

@golemparts I'm getting the same error in most recent version :(

Hi @Jezorko. The error you're getting likely means your Raspberry Pi doesn't have a /dev/spidev0.0 device. Make sure you have SPI enabled and configured properly. Follow the steps found here.

If you do have a /dev/spidev0.0 and are still getting an error, please open a new issue so we can look into it further.

Thank you @golemparts, this worked!

I found this issue after I reported mine #154

Was the HW pwn tested and where there OS settings I might have missed that where not documented?
