Just to clarify: the physical resolution of the PicoCalc display is 320x320 pixels. I have been experimenting with several console fonts because my eyesight is not great, so the font you see in my photo may not be the default one. I think in that image I was probably using a font called Terminus14.
There is a whole Terminus font family, with different sizes. Some are around 6 pixels wide, while others are wider, and the heights can vary roughly from 8 to 20 pixels depending on the specific font.
So I don’t think you are doing anything wrong. What you are seeing is probably just the default console font being larger/wider than the one in my photo.
Have you tried accessing the PicoCalc from Linux using adb? That can make it much easier to change fonts and adjust the console setup.
If you’re not sure how to change the font, I can try to help you tomorrow with the exact steps.
The physical screen resolution of the picocalc is strictly 320x320; there is no such thing as 480x320. The 8x8 font you are seeing is simply because the Linux kernel used in these images only includes that specific font.（）Some system ROM developers enable the font compilation option in the kernel configuration, allowing you to see the 6x12 font right from the boot stage.）
If you don’t want to make major modifications, you can specify the system font after boot by adjusting the system settings in Ubuntu. (Note: apt requires an active internet connection. I assume you have already sorted out the Wi-Fi hardware or connected via RNDIS)
# Set the console font
sudo apt install console-setup
sudo dpkg-reconfigure console-setup
Just select the 6x12 font in the interactive configuration menu that pops up.
I was surprised it wasn’t showing in “ip link” at all since it works by default in calculinux and I thought several people in this thread were using it also. I tried locating and enabling modules for the wifi adapters (which are available in the 6.1.99 kernel) using make menuconfig I noticed 8xxxu and was hopeful but this didn’t work. Do I need to push a driver package via adb and install it that way? Which package has worked for everyone?
I can confirm that the RTL8188 series chips are not included in the Luckfox kernel source code (unless a developer has specifically adapted them like the calculinux did). I have always been using the independently compiled .ko module by myself (provided by @hisptoot).
One important thing to note about this Wi-Fi driver is to remember to copy the firmware file to the designated location accroding to the makefile.
Struggling through this! I got ubuntu 22.04 running in a vm and was going to grab the sdk to compile the module but couldn’t find it anywhere. Where is the sdk for the lyra? I could only find one for the pico.
Since you already have an Ubuntu 22.04 environment set up, I would be thrilled to invite you to try out my Linux kernel project. I am currently basing it on a 24.04 rootfs as well, but I’ve customized the content and addressed quite a few of the shortcomings that people have criticized about picocalc!
well I have to thank @hpsaturn for all you work getting Chess going on the picocalc. I was able to get everything runig on my luckfox lyra with the luckfox SDK build. had to tweak a few things and already had the truetype fonts working. SDL2 came compiled in my build already. But it is running and and well at that. I am a little confused in the initial screenshot I can see the moves on the right of the screen. I might be missing something but that feature does not seem to be in the code. But I am very happy, thank you.
