Tiny screens for your Raspberry Pi projects

- What is that raspberry pi doing right now? beats me!? Let's put a little status display on it. In a radio context, this could be APRS stations, ax.25 traffic, or possibly display apps like wsjtx or js8call. With a small tft screen and a bluetooth keyboard, you can build the ultimate light-weight, low-power summits-on-the-air digital rig.
1.3" tft screen SPI ST7789, PiZero form-factor ($15)

(DigiPi ready)
2.8" capacitive touch screen SPI ILI9341, Pi4/5 form-factor ($44)
www.adafruit.com/product/2423
(DigiPi ready with newer version of direwatch.py, digibanner.py at github.com/craigerl/direwatch)
4" square 720x720 60fps gpio monitor ($67)
www.adafruit.com/product/4498
Put "dtoverlay=vc4-kms-dpi-hyperpixel4sq" in /boot/config.txt
This is not a DigiPi display but an actual X11/wayland monitor

This video is not sponsored by adafruit, but I like to support their open source work by giving them sales referrals. Most of this stuff is available on Amazon and other grey-market versions are available world-wide. - วิทยาศาสตร์และเทคโนโลยี
wow. Not just low-power and light-weight, but low $$. This could easily replace those 12v Evolve laptops everyone lugs into the field. I am loving this channel.
The great content continues! Thank you.
They are great Craig. Thanks for sharing a Xmas list for my wife to buy me. Haha
Nice video.
Great video Craig! You may have already done this, but how about a video showing the hardware and software installation for one of the screens? Would certainly help us old non-programmers. Thanks!!
Hey Bob, check the last link in the description to see adafruit's configuration documentation, it's top-notch. Better than I could ever do !
@@KM6LYW Perfect!! Will do. Thanks.
Im here waiting
You are doing cool things and analog design cannot do. Yes I have built many APRS digipeaters but you have gone farther. Now I did see your new analog board yes I want to see that one. Keep going is helping the ham world.
I just got my RPi5 but not a Patron. Maybe I'll pony up and try it when I can 😮💨. DragonOS looks interesting.
Please talk about the radio interface board soon! :)
shhhhhh, still secret, more soon
Please show that radio interface board ASAP. Looks grerat!
Great work. This could be what I am looking for. I like to make a very small HF APRS tracker. DigiPi maybe the answer. I have few questions, can you help me out. I like to use QMX radio and DigiPi together to create a HF tracker. Can we add GPS and make it happen? Can we run fldigi to do CW through digiPi with QMX? Thank you very much.
Hey, i know nothing about the QMX, but digipi can use a gps, for time (ft8) and location (TBEACON in direwolf).
@KM6LYW how about using the likes of the Nextion screens for low refresh rate status display?
My screen driver works with the ST7789 and more recently ILI9341 screens. Essentially anything adafruit supports.
KEWL!
I'd been looking at one of those tiny monitor displays for my pi. I hesitated, because the WSJT-X docs say the minimum screen resolution is 1024x780, and most of them are 800x480 or 1080x600. Have you run into any sizing problems with the 720x720 screen from this video?
i was able to call CQ in the video, ultimately make contacts, but you'll notice some of the buttons were a bit hard to read since they were a bit squished. It's feasible, but I bet 1024 would be best.
DgiPi Dark mode on the way?
Not sure about little screens....seems Node-Red and a tablet, phone, PC a way better way to go and probably much cheaper!
Is there a 7 inch screen you would recommend for Digipi? I need the larger display. Thanks
DigiPi will drive an ST7789 or ILI9342 display. I don't think they make a 7" version, as they're typically low-res.
where can I find screens that have a cable instead of being soldered directly onto a board?
I might suggest an HDMI monitor in your case. The screens in the video are connected via the GPIO pin header, not soldered.
@@craig9309 thanks, I looked at some options, I think I can probably retrofit a mobile phone display, not sure how to get it thru a hinge but I have some ideas
have you tried the epaper ones and compared current draw and battery life ?
I don't have an e-ink display yet. stellar battery life, but low refresh rate. The blinking LEDs for transmit/receive need a higher rate.
@@KM6LYW i would just add a physical led somewhere if i felt i needed that or just just a low refresh TX status
Radio control circuit? Another video? Hmmmm.....
DEE
YES! nailed it, thank you, I was starting to worry we didn't have any Ozzy/Randy-Rhodes fans here
