That’s good to know. Game On. =)

Button problem / New Picade X Hat broken?

Arcade Retro Clock HD
I’ve seen the code for the Unicorn 8 x 8 but could you please share the code for the HD version, I’d really love to get my hands on this.
Thanks

OnOff Shim Problem?
Just added OnOff Shim to RPi4 which has an adafruit GPS. Checked the connections.
The RPI will only start up when I keep the button wires held together (ie not momentary). When I do that, it then starts to shut down.
There seem to be other posts about this. Is the device faulty do you think?

Connecting and saving files to a NAS
Can anyone suggest a link on how I can do this?
I want to duplicate my Enviro data on my NAS for security/safety, by adding it to my Python code.
Thanks

Connecting and saving files to a NAS
Do you have some more details about the NAS? If it is not really necessary to do it via the Python code and you have a Synology NAS you could use these instructions:
How to back up Linux computer to Synology NAS
I don"t know anything about how the Enviro data is saved, but if it are files in a certain folder and you have a Synology NAS it should/might work, at least it did for me some time ago. Good luck!

Pirate Audio Headphone Amp - No Sound
Hi, I’ve just set up a new Raspberry Pi 4 with the Pirate Audio Headphone Amp.
I’ve disabled the default audio in /boot/config.txt, and can only see one device after aplay -l etc…
I’ve enabled SPI and I2C
Iris launches, I can see the mp3 lists from the local directory, the buttons work, the mini display shows the playing track details (selected from the web interface locally and from my mac), but no sound.
I’ve tried different headphones.
Is there something simple I’ve missed?
I’ve read most / all the related posts although the fixes seemingly have been rolled into the git repository by now.

Connecting and saving files to a NAS
Thanks for the link. I have a Synology NAS so it should be helpful, I will have a read.
The reason I said ‘adding to Python’ was because my code currently saves to the SD every 5 minutes and graphs the data with Nopheads EnviroPlusWeb app and Grafana so I thought it would be the place to add a save to NAS line.

Pirate Audio - No Sound
Hey! I got the Pirate Audio - SMOL Speaker. This is my 2nd one. The first one was defective as the display never worked.
So I got this one and it seems I am doing something dumb. I can’t figure it out.
I’m using a Rasp Pi 4B and I’ve tried full version and the lite version.
I’ve also gone into the boot config and ensured it said:
#dtparam=audio=on
That didn’t work.
Any idea?
Thanks!

Actually I think its
dtparam=audio=off
and
dtoverlay=hifiberry-dac
gpio=25=op,dh
In config.txt

OnOff Shim Problem?
The on off shim uses the following GPIO pins
If the GPS uses any of those pins (other than power and ground) that may be your issue.
How is the GPS module wired up?
↧
OnOff Shim Problem?
The gps hat sits on top of the OffOn Shim which sits on the RPi. The OffOn Shim is soldered to a header with long pins which allows the adafruit gps header to be pushed into place. That is, the Shim is sandwiched between the gps and RPi.
My reading of the description of the Shim is that it works with Hats. Maybe not all hats?
↧
OnOff Shim Problem?
Sorry - just got your point. Yes, they do share Pin 7.
Does that mean they cannot work together?

Pirate Audio - No Sound
Awesome. I’ll test that. Thanks.

OnOff Shim Problem?
The two sharing pin 7, GPIO 4 is likely your issue. What does the GPS use pin 7 for?
↧
Pirate Audio - No Sound
All those other things were fixed.
When I have the desktop, I did hit the mopidy button to start it and I noticed that there is an: Audio output set to “autoaudiosink”
Is that right? Or how do I change this?
Thanks,
David

That I can’t help you with. I have a Pirate Radio, the older pHat Beat one, and I just run VLC Radio to stream from the internet. I never tried anything fancy. =(

OnOff Shim Problem?
Ah! Adafruit say: " GPS’s can output a ‘pulse per second’ for synchronizing the time. We have a breakout for this and a closed jumper that connects it to GPIO#4 - if you do not need PPS and want to use #4 for something else, just cut the little connection on the PPS PCB line."
↧
OnOff Shim Problem?
Ok, I have an older version of the Adafruit Ultimate GPS breakout. It uses UART or a serial to USB adapter. I’ve used it both ways on a Pi. I can’t find a link to the one I have though? Only the newer version 3 one. Is that the one you have?
EDIT: You must have the hat version? Mine is a breakout that doesn’t plug directly into the Pi’s GPIO. I would cut that jumper with an exacto knife. You can always just solder it back in place if the GPS stops working.

Thanks, alphanumeric: here’s what I’ve got:
# Enable audio (loads snd_bcm2835)
dtparam=audio=off
[all]
#dtoverlay=vc4-fkms-v3d
dtoverlay=hifiberry-dac
gpio=25=op,dh
Everything else seems to be working fine (thumbnails, gui, comms from the buttons to the web app and vica version… all except sound.
