I’m also an RPi pico user, it’s cheap enough and the sdk is not so terrible.
And of course the Teensy 4.1 when something more heavyweight is needed.
OK, we are in sync here too!
BTW: the H750 has, in fact, the full 2 MB of its larger siblings, one just needs to lie a bit to the toolchain…of course, no guarantee it all works and is reliable, but for a home project it’s good enough!
The new RP2350 chip is quite interesting, with its choice of cores.
The Cortex-M33 is much more efficient than the M0+, and having a (single precision) floating point unit is a great boost when needed.
The included RISC-V cores are also interesting, I think it’s a first step to transition away from Arm: they have designed them in-house, after all.
We’ll see the reception, but I find it a good move.
Also the line-up with larger chips with more GPIO and internal flash makes the RP235x more interesting in a wider range of applications.
The PIO has been talked about a lot, more is of course better.
It still, IMHO, remains a hobbyist/maker oriented MCU, it gained a lot of traction in industrial applications during the pandemic, as it was one of the very few MCUs not in shortage, but some choices are a bit strange (and the docs are quite ugly, TBH, wrt NXP or ST documentation).
Did they keep the asinine way to address the two cores during debug (two separate DPs)? (cheks DS…)
No! They aren ow on two APs (as 99% of all >1 core MCUs), finally a reasonable way to have simpler dual core debugging!
Note: all IMHO, YMMV, I have not gone fully through the DS, but gave it a good read in the changed parts already.
