Derek,

I couldn’t agree with you more about COS and PTT!

That’s the beauty of open source software. Anyone can contribute and add features that they want.

I am sure there are a lot of folks that would love for you to add these features to the app_rpt open source project for Allstarlink.

In case you didn’t know where the repository is located, its here.

https://github.com/AllStarLink

You know you can use the CM119 chips and these are only a $1.35. (Quick google search)

The issue is that the CM108 chips are becoming harder to find and more expensive. There is currently 1 seller in the US on eBay with them, and they’re charging a premium price. I wanted to build a node, but why on earth would I pay more than the combined cost of the computer and radios used to run the node to get an adapter, when all of the necessary hardware is right there?

ASL needs a way to configure an alternate mechanism for COS and PTT. It shouldn’t even necessarily be GPIO specific, e.g. using serial would be useful for some people rather than GPIO or CM108.

I didn’t hand much luck since current forms of AllStarLink and even Hamvoip do now allow for RPI GPIO. I had to use the CMxxxx audio USB for PTT and COR

Joe;

Had you found a solution to using R_Pi GPIOs as an alternative to purchasing a USB dongle.
I have a repeater already working (SVXLink) that sounds fantastic and I’m in the process of switching over to AllStarLink and was hoping I could just change software without any hardware changes.

Greetings,

I’m new to the group here and have some questions regarding All-Star link. I have a raspberry pi already set up with an HT radio (baofeng) and I was using svxlink node. I already have the radio wired up to use the GPIO on the raspberry pi for a PTT and COR. I use a USB dongle for audio and I am not sure if it is the same one that is used to modify and tap the GPIO pins, But I was trying to find a way to use the GPIO from the raspberry pi instead, since it’s already configured that way and works with SVXlink. I have been finding information on the Internet that suggests that the All-Star link software can be configured to use the RPI GPIO pins but haven’t found any solid documentation to do so. I was going to jump back in and look at the configuration files to see if there are any clues there but if someone has done this already can you please clue me in how I can use GPIO from the raspberry pi.
