I've just published a blog post on fast bitmap font rendering for RP2350 and other microcontrollers. This was a fun little project, which pushes the limits of low-level optimization, and also involved some creative work on the font, especially kerning.

back in the 4o days, making this was a pipe dream of mine that I worked on with 4o and basically didn't get anywhere with. now you just give opus 5.5 a couple hours and leave your microcontrollers plugged in and it can just do it.

Going from planning out a desktop build to looking at microcontrollers for projects is a wild experience. I've had the following thoughts within an hour of each other:
- RAM is expensive but 32GB might not be enough for me so 64GB it is
-Wow this has 256K of RAM? That's basically infinite memory!
- RAM is expensive but 32GB might not be enough for me so 64GB it is
-Wow this has 256K of RAM? That's basically infinite memory!

Yes, radix, bucket or insertion sort all look quite promising as optimal. This is interesting because of previous work I have done on microcontrollers, where even bubble sort is sometimes favoured in situations that aren't dependent on relatively "fast" sorting.
