Right shift key is mouse mode toggle key in new kbd driver.
Arrow keys control mouse move and square bracket keys control mouse button.
Mouse mode should be useful in pico8 editor.
I installed hisptoot linux (buildroot)_20250419 version and confirmed it.
At that time, I was trying various things, so I don’t know exactly what process enabled mouse emulation.
If this is related to the keyboard firmware,
Keyboard_firmware in hisptoot’s Google Drive described in
may be what will do it.
Or it could be the official latest keyboard firmware
For “PicoCalc and RasPiZERO2W”, I prototyped a PiZero cover for the back panel of the modified PicoCalc and uploaded it to Thingiverse.
I also described how to make a simple relay board.
It looks like this.
I just sent off a first attempt at an adapter board that includes the following:
The Pi Zero 2W footprint (on the underside of the board, to save space)
A 4-port USB hub, with connectors (QWIIC style, though of course not compatible) to bring the connections where needed. There’s a small header to interface with the test points (I’m not sure whether I’ll use low-profile pogo pins, or just wire wrap): SL2.1A | CoreChips | Price | In Stock | LCSC Electronics
Has anyone figured out how to run dosbox or pico-8 in cli with the pi zero? They run fine with the gui but I like the idea of running everything cli. I get a black screen with dosbox and I have copied the config file from the lyra. When I run the pico-8 I get an sdl error. I’ve started to create a crude bash menu that I’d like to boot up when the pi boots to cli.
It’s a bit crude but I got gui apps running on raspberry pi os lite by installing the xserver package and adding exec (Application run command) to the .xinitrc file before running startx, I use bash scripts to change xinitrc files. Here’s my .xinitrc file for launching pico8 in fullscreen
exec ~/pico-8/pico8_dyn -draw_rect 0,0,320,320
And here’s my pico8 launch script.
#!/bin/bash
rm ~/.xinitrc
cp ~/pico-8/.xinitrc ~/.xinitrc
startx
wait
clear
exit
Just a quick update — I’ve populated most of the parts (except for the ESP32), and only begun testing. It does power up, which is a positive sign, but that’s the extent of my testing so far.
This is really amazing.
I am looking forward to see your progress.
I hope, you’ll release this open source one day.
(Although I am not sure, that I’d get the soldering done on my own.)
Exciting job！now seems the biggest cons of this machine is the Low resolution of the screen and the strange keyboard layout（the “shift” way of activate assistant keys like F6～F10/home/end make it impossible to perform combine keys like “shift + home”，one more “Fn” key would be a better design）
