Me too, I refuse to do any soldering on my PicoCalc, I am perfectly capable of doing it, I just don’t want to. I am using a Lyra though, but since I don’t play games, I don’t really need sound for anything.
You can try this no mods required for sound GitHub - nekocharm/picocalc-luckfox-lyra
Or this ubuntu GitHub - markbirss/ubuntu_22.04.5_lts_picocalc: Ubuntu 22.04.5 LTS for PicoCalc with Luckfox Lyra Core
How does this work? Emulating pwm on the needed pin?
Regarding the sound noise issue, the hardware uses PWM output audio, so the mute on the hardware is duty=0, but the software uses U8 type data, which causes duty=128 when the mute is used, so there will be a noise when the audio is played, I don’t know how to deal with this problem, I think it’s a hardware problem
That is a nice solution for people that don’t want to solder on their picocalc.
Hey guys,
Let me know if anyone is able to run Emacs with the GUI on the Lyra. Emacs would be the perfect starting point for building a full-featured graphing calculator on the picocalc:
- calc-mode for RPN calculator and graphing
- casual-calc or custom user interface to organize commands (see calc-commands here: https://www.gnu.org/software/emacs/refcards/pdf/calccard.pdf)
- algebraic or latex input
- render latex on the calculator’s stack
Take a look at this demo of Latex rendering and custom menu for calc-mode:

I have gotten text mode Emacs to run, but I had to strip a lot of stuff out of it to get it to compile properly and run. You will need a custom build of the Linux image to get everything you need. It is doable, I just don’t know how usable it will be.
Thanks for your work, I fixed the bug of the script.
Is there a git command?
I am most solely use (programming) pico 8 on my device and manually syncing my games via SD card is a bit disgusting…
