Hidden Features and Modifications

While the DigiPi web-management interface will get you running in just a few seconds, let's take a look at some other changes we can make under the hood to customize your DigiPi just how you like it.

I've been watching all these videos, awesome stuff. I will say that when I set this up to connect to a Digirig.....I used the 115200 buad rate with the usb mini to usb c cord I got....and it worked perfectly. Really like this setup as a way to interface to many different platforms.

[@datagod]

This video really helped me, thanks for doing this.

[@digitalnomad46]

Thanks Craig for the video! Nice to learn some new tricks on the digipi. Would be nice to have in the initialize part the option to add a few extra optional apps. Have added gpredict to my setup but it took me some time to figure out where to make all the edits so that I can run gpredit the same way as js8call for example. A suggestion would be to add gpredict and other apps (e.g.qttermtcp) as optionals in the initialize section in case people want to have those as well 😉. Thanks again for all your hard work with this project, have been enjoying this a lot.

[@KM6LYW]

Yah, i use gpredict on my pc, but not on the Pi... no real reason. I'll have to look at the memory footprint with gpredict. would you run it along side a satgate?

[@JeffHochberg]

Gloss you’re using the domain Craig! I hope all is well! We need to get you playing some more obscure Zeppelin songs. I rocked out to Coda yesterday. Favorite Zep album by far!

[@KM6LYW]

Man, I almost did Kashmir today too. Gotta be short, recognizable, and something I have done yet ... the list is getting shorter :)

[@JeffHochberg]

@@KM6LYW I can come on and play Blackbird! I think it’s the only tune I remember how to play!

[@dangermandave67]

Thanks, Craig. I've been thinking of using DigiPi to run a 30m APRS station with a (tr)uSDX in the field. At the moment, CAT and audio with this radio involves a horrible wire mess, unless you want to use a firmware beta and a driver written by Guido that wants to map to a specific fixed numbered port (no thanks). The way people like OH8STN do it is run CAT with the (tr)uSDX port and then run the audio through either the onboard soundcard or something like a Digirig. So you've got two USB connections to your computer; one for CAT, the other for audio. Messy, but it works and that's how I'll keep running it. Question for you: is it possible to hack the DigiPi to work with this messy interface to the radio?

[@KM6LYW]

additional complexity points! :). DigiPi can be tweaked to do serial-port-RTS for PTT, which is what digirig uses. Cat control is another thing, which generally requires hamlib support. The next release of DigiPi will have an RTS/DTR option up front.

[@dangermandave67]

@@KM6LYW yeah, (tr)uSDX is far from perfect, but if I just want to have a very lightweight 30m APRS solution to work alongside the main radio I use on SOTA activations, I think it will work. Add a RPi and a 10 inch Android tablet, and I think it's about all I'd need to send out a SOTA spot on 30m APRS in the event I couldn't hit a VHF digipeater. For that, RTS will work fine. If I want to use other digital modes, I'll probably have to have CAT control. So do you think having those separate USB cables coming in is going to present a problem for the DigiPi?

[@JoeCupano]

Awesome work !

[@ghostmandka5498]

Missed that bumper music!

[@plankton9864]

Thank You. I would love information to get attached USB GPS info to display on Direwatch. Bryan S

[@hudsonriverlee]

Awesome Led Zeppelin..

[@bradgreenwood2588]

Can you change the Webchat APRS symbol and beacon text? Can't find the right .conf file to do this.

[@Ko4vhb]

Awesome I just bought the software and I’m trying to ssh out I the digi pi what’s the password so I can connect to it

[@KM6LYW]

digipi.org should have the answers. the digipi login is the standard raspberry pi default user and password

[@Dontcopit]

Hi mate, I know its a big ask, but for multiple reasons other than the fact I cannot operate without dark due to photosensitivity, is there anything that can be done to get all that white stuff black and black stuff white / green. Etc. Not expecting a miracle. Would be beneficial for night use. Bravo Zulu on the work. 73's

[@KM6LYW]

it's open source, so there's nothing you can't hack to your liking. checkout /var/www/html/simple.css background-color: #fdfdfd;

[@Dontcopit]

Thank you @@KM6LYW

[@DonzLockz]

​@@KM6LYWWould it be hard to make a dark mode option?

[@craig9309]

hey, sure, you could edit the style sheet for the html

[@SpookieNZL]

Craig, also I'm trying to Just try the new PTT Device AIOC PTT Board. Wonder if this would work like a DigiRig Interface. Would you be happy to try and make a New Video with the DigiRig since you said you own one. Be interested in that. 73

[@KM6LYW]

Hey Spookie, is that the board with the optical isolation relay? I don't have a digirig/signallink or any of the cm108 solutions in that regard.. i should probably give them a try.

[@W4TRI]

Does this work with a Digirig interface? I don't solder due to vision and can't make the interface. Thanks!

[@KM6LYW]

Yes, see the spot in this video for the file to tweak to make DigiRig and SignalLink work with DigiPi (add "PTT /dev/ttyUSB0 RTS" below the PTT lines in /home/pi/direwolf.tnc.conf).

[@W4TRI]

@@KM6LYW Went back and watched it again. Is that where you called it Sound Link? You mentioned you never used one. The Signalink and Digirig are the most popular interfaces going now. They are more featured clones of the same sound card interface people have been building since packet radio days.

[@KM6LYW]

@@W4TRI yah, i screwed that all up, i meant SignalLink and DigiRig. both are cm108 usb audio with a gpio pin, and assert ptt when RTS is high as far as I know.

[@direhavok8732]

What is proper resolution for FT8 & JS8call running on Phone?

[@craig9309]

i overheard the minimum resolution was 1024x768. this can be tweaked by editing /etc/tightvnc.conf (geometry line)

[@juggalizzle75]

where can I change the port 5901 that the pi listens to to bring up the web interface when not connected to local wifi? I have another program that uses that port on the same pi that i can't figure out how to change.

[@KM6LYW]

look at wsjtx.sh, js8call.sh, sstv.sh, fldigi.sh -- you'll see the xtightvnc server start there and you can specify the port on that line. all the links in /var/www/html/js8call, wsjtx, sstv, fldigi will need to change as well.

[@jameslee522]

Can you make a video on adding a temp sensor like the bme280? I know direwold has telemetry options but it's over my head. I would like to use my digipi to report the temperature inside my rv while away.

[@KM6LYW]

Hey James, I would if I could, but I don't know how to dynamically generate PBEACONs in direwolf, with variable data. I wonder if that's a feature? I never saw it in the direwolf docs. I think we'd need to hand-craft an aprs packet, then send it to direwolf using kissutil for transmission.

[@vzwopx]

I love this project but sourcing the audio interface is giving me some trouble. Is there alternatives?

[@KM6LYW]

Budd has the FE-Pi audio board in stock, ham made (just talked to him) www.wb7fhc.com/order-nexus-now.html . You can try USB audio dongles, they work but be aware they are mic-level, not line level.

[@vzwopx]

@@KM6LYW Hey, thanks for the reply! Sadly I'm not in or from the US so I'll have to find a different source unless I want to spend a lot on shipping. What do you think of the idea to make a little wiki for the project where people can share tips and tricks and also keep a list of suppliers that have things in stock in different countries? I think it would be really helpful! Keep up the good work :)

[@MrVertigo1971]

Please show, how to add customs rigs to Digipi's config. Thanks.

[@KM6LYW]

DigiPi supports all the Rigs in hamlib, and/or PTT via a gpio pin. Do you want DigiPi to support more than one rig? I use different SD cards for that.

[@Oldcomputer]

Is there a way to make it start NODE by default? I want to place at remote spot with unreliable power and need it to come back in NODE mode.

[@KM6LYW]

Sure, put "service node start" in /etc/rc.local, after running "sudo remount". put a pound/hash sign in front of "service tnc start". Great suggestion. Also feel free to put the same in /home/pi/digibuttons.py so the little buttons on the screen will start node, tnc, digipeater, etc.

[@unixbehr]

Graig I want to know if you have a install script so I can install on diff hardware? as pi are over priced for whar they are and I have like 25 other boards I can use. ...

[@KM6LYW]

You can check my github account for all my modifications/code at github.com/craigerl , however, it is non-trivial, will be a challenge getting it to work on armbian. A raspberry Pi Zero 2W is $15 and in stock.

[@danadkin8652]

Could CQRlog be added to Digipi?

[@KM6LYW]

yah, i could/should add all the different loggers

[@wild-radio7373]

🥰👍

[@MeineVideokasetten]

Image for $$$? *Sorry. No.*

[@n5yiz]

It's $5...what do you think it's worth?

[@vzwopx]

It's only $1 even. Just do it. I think we can afford that as people that have 1k+ in radios at home
