@byron @inq Interesting but I didn't see any mention of the kernel-level library.

@inq @zander

The following may be of interest as it seems to have been updated this very day 

https://raspberrypi.stackexchange.com/questions/117591/controlling-raspberry-pi-gpio-with-c-and-python/117592#117592

The Pi5 uses an external chip for GPIO which appears to break most of the existing GPIO libraries.

 

Yeap!  That's what I'm running into... even on the Pi4.  And is my point... RasPi.org should be responsible for the low level API and others should use it.  That allows them to change chips, change the API and no 3rd party libraries break.  Having 3rd party going to the chip level (BCM2835) means a brittle architecture.  As illustrated, it's good  (ahead of time) to know that Pi5 doesn't use that chip.  Will that nice developer re-write his library for the new chip?  😘 or kiss the headaches away.

@inq

vscode is also available on the rpi, and easily installed from the options > recommended software menu option.  No doubt from my previous post (your last post crossed) you will see more C options to explore.

Yes rpi does keep providing more options, or shall we say, as more people contribute their 3rd party options.  However, back in them days it was a lack of C or C++ stuff for the rpi that drove me to python, and now I'm mightily pleased it did so 😀

@inq @byron libgpiod is now in the kernel. I doubt that will get broken easily. HOWEVER, the Pi5 has a totally different GPIO setup, it would be really interesting to see what of the possible solutions already work/will work. I will be surprised if the Pi5 GPIO support is not in the new kernel. I will test it when I get my Pi5 in a few weeks.

Do you use it?  I loaded.  It was still slow even on a RasPi 4 (64bit OS)-8GB... at least compared to Geany.  It didn't compile out of the box.  Probably needs a plug-in.  Does it do real debugging?

@inq What developer? The gpio library was moved into the kernel some time ago. I will test it when I get my Pi5. AFAIK, the kernel is maintained by the RaspberryPi folks.

I've had my two sitting on my desk for a couple of weeks, so the colonies are a bit behind the times 😎.  

As I know you use a mac the one thing that I found missing from Debian Bookworm was that netatalk was AWOL to install via apt.   This was due to the fact that Netatalk did not have any maintainers for a while.  However it does have one now and it should be incorporated again but probably not for a year or two!!  But I found a way to install the latest version via apt as an unsupported version and if you want so info on how to do this then let me know.

@inq - it goes to show that its a fragile world with these here today and possibly gone tomorrow libraries and not just related to rpi stuff, but what to do?

Debian Bookworm

They also broke VNC Server on it.  I use the RasPi headless.  I had to back up to Bullseye.

@byron No idea what netatalk is. Not surprising that the UK would get preferential shipping, I am sure we do the same with Maple Syrup and Maple Syrup beats a Pi5 every day.

I have far more things to do so I don't miss the Pi5 besides, I don't really have a use for my Pi4 let alone Pi5.

In addition a new puppy and ongoing health issues means I will probably not be able to do even as much next year as this which was maybe 10% of what I had planned.

vscode Do you use it? 

I have used it, but rarely on the rpi as I tend to use it on my mac for coding python and then transfer the code to my rpi.  I dont use the GPIO much on the rpi, but use the rpi pico and esp32's for that sort of stuff.   As one can now use vscode to program micropython on the rpi pico I have tried vscode out on the new rpi 5 where it runs very fast. 😀

@inq Me too (headless that is), glad I didn't upgrade yet.

Oh, well its how you can use your mac finder to look at the folders and files on your rpi and easily transfer files to and fro.

Enjoy you new pup,  the dog walks should give you some nice exercise, but maybe strap a rpi with gps tracker to the hound. 😎

Microsoft Remote Desktop works OK with Bookworm, also TigerVNC viewer works well, on my mac anyway.

@inq - In case you were thinking of using ms Remote desktop there is some small setting up to the config file needed on the rpi

XRDP ms Remote Desktop:

sudo apt install xrdp

To enable user pi to work with XRDP:

Edit: 

sudo nano /etc/X11/xrdp/xorg.conf

In xorg.conf find :

Option "DRMDevice" "/dev/dri/renderD128"

Change to:

Option "DRMDevice" ""

Save the file and then reboot

@byron Ok, that's probably Apple talk for SMB or CIFS. I don't have much need to network the Pis into my home network, but if I ever do I will remember that. Thanks.
