Did you lose the source yourself or did it arrive like that?
The latter.

(Asking the original programmer won't help unfortunately. I can't find them.)

Re: Anyone had experience with PicoScope Oscilloscopes?

To chime in, far too late. A cheap option, depending on what you want to do, could be to use a bus pirate. Look it up. Another option is to get a logic analyzer. Search a bit. : ) And then you have your Keysight X1000 series, that aren't THAT pricey or the various Chinese brands, that I will comment...

Have .o file but missing .c, can I compile?

Really Really Dumb questions time! So I've got source code, but in two cases I've only got .o files and not .c/.h files. Could I still (theoretically) make this compile? The .o is a file that's build from a .c and ready to link after all? But practically, and not theoretically, would this depend on ...

Re: Can't get sound from 3.5mm jack after mistakenly loading ALSA sound control?

Thank you. :) It didn't work unfortunately. I can see the audio output in the pulseaudio-utils, under the leftmost tab. But I get no sound in my headphones (that work, I just tested them). Some data stream is missbehaving somewhere. I tried pairing a bluetooth speaker, it pairs just fine, and I can ...

Can't get sound from 3.5mm jack after mistakenly loading ALSA sound control?

I did the upgrade as per the blogpost: https://www.raspberrypi.org/blog/new-raspberry-pi-os-release-december-2020/ The sound on the 3.5mm jack worked, but the volume control in the task bar was gone. I was dumb and missed the part about the Pulseaudio volume control, so I put the ALSA one there and ...

Re: Hardware problem

I'll leave the actual question to other posters.

I'll add one of my own instead, to the OP: Are the pads in a state so that you could replace it, and how will you avoid heating away the other components around that area?

The Achorn 400 as a homage seems like a decent guess. And as an additional bonus, once the 5 drops, we might get an A500 (like the Amiga : ) ).

Those terminals won't fit on the Pi. You'd need to mount it onto another board and then wire it all back to the Pi Zero.
Wouldn't it work for a singular row? (Or two I guess, if you'd make the secondary row jut out from below and be fine with it).

I suppose he could put a female 0.1" 40 pole connector on it. He'd still need a pin attached to a wire to connect it to the bread board or whatever, but perhaps that would have better connector springs than whatever it is that OP uses to connect to the pins of his boards? You could wire things ...

This gives me Amiga vibes. Nice. :)

I'm guessing the lack of a headphone jack boils down to the need for a large customer base to have audio in.

Good job, to everyone that's been involved. :)

Re: why does the CM4 have an onboard PHY

I suppose that the lemma of what the above poster said, would then be that it's interesting for such a large portion of customers that it makes sense to put the PHY on board rather than saving that cost / enabling another feature / making the CM4 smaller.

This got me curious as to what "bulk" means, in this case. And if Farnell is any indication, it's 200 units.

Not too horrible for small makers of this and that.

We'll see what happens. But say that nVidia turns out to be the perfect ARM owner, in terms of respecting the current licensing model and what not. I'd still not expect to see an nVidia GPU in a Pi or a Pi priced computer any time soon, or after. nVidia likes their money, and will have little reason...

Do you have equipment to look at the communication, like an oscilloscope, logic analyzer or such?

It might be interesting to see what is really happening with the communication when you issue your commands.

Then, remembering that double buffering eats bandwidth/power consumption, and it takes effort to implement... And I'd guess ...
