Disappointed that MicroPython's policy on AI isn't a staunch: "Fuck off into the sun."

Yeaaaaaaahh so MicroPython's `machine.Pin().toggle()` is broken on RP2350B (> 32 GPIOs) and that's probably my fault for missing the wood for the trees.
And I only discovered this because someone reported that the output of `__repr__` / `__str__` was broken.

MicroPython's nlr_push/nlr_pop exception handling is both wild and also basically just `goto` with extra steps 🤣

Tbf knowing about PSRAM support in advance would have robbed us of this art.
PSRAM combined with MicroPython’s garbage collection is a horrorshow though 😭 need to do something about that.

What’s surprising though is *how* costly lookups are in native, I guess it still has to use the indirection of MicroPython’s qstr setup, lest a method be moved, removed or redefined?
But a simple variable in local scope? Ouch!

Should probably delve in to how they solved the same problems I ran into, but I’m not simulating hardware so much as making MicroPython’s WebAssembly port more useful.

"That path resolved rng_get() to MicroPython’s software fallback instead of COLDCARD’s hardware RNG implementation." 😂

Three is definitely enough but then there’s one entry point main and a _main and also another main because MicroPython’s Unix port and Sokol both want to be top dog.
Making the two work together might be… spicy.

BEAPER Nano and BEAPER Pico are designed to be simple for beginners. LCDs panels, not so much. 🤷
So, I've extended Russ Hughes' st7789mpy driver to use #MicroPython's frame buffer while providing a simpler interface for beginners. Check it out! 😃

(To the credit of MicroPython's maintainers, if it ain't broke don't fix it- they use a somewhat modified version of FatFS called oofatfs, and the addition of "n_fats" as an option to "mkfs" means updating to 0.14+ will break a whole bunch of stuff.)

My test program lets met write to the LCD directly, or use MicroPython's frame buffer (as shown in this video). But I still need to add a library to write larger text sizes and investigate an ellipse crashing issue on the Pico 2. 🤔

Met with exactly these challenges upstream in MicroPython, when adding PSRAM support for the RP2350. I would very much like "m_malloc_without_collect"!
There's also discussion of an attribute system for memory since PSRAM cannot contain DMA buffers, and other such pitfalls.

MicroPython's 8x8 pixel frame buffer font is too small for the 240x240 pixel display on BEAPER Nano and BEAPER Pico, so I'm working on designing a custom 16 pixel high font that I can build into the MicroPython LCD display driver (top of both photos – bottom is Reddit Sans 16). What do you think?
