I got almost all of my wishes granted with RP2350

I think it's a good way to introduce these chips, and it's a great project, but the author's (frankly weird) beef with STM32H7 is detracting from the point they're trying to make:

> So, in conclusion, go replan all your STM32H7 projects with RP2350, save money, headaches, and time.

STM32H7 chips can run much faster and have a wider selection of peripherals than RP2350. RP2350 excels in some other dimensions, including the number of (heterogenous) cores. Either way, this is nowhere near apples-to-apples.

Further, they're not the only Cortex-M7 vendor, so if the conclusion is that STM32H7 sucks (it mostly doesn't), it doesn't follow that you should be instead using Cortex-M33 on RPi. You could be going with Microchip (hobbyist-friendly), NXP (preferred by many commercial buyers), or a number of lesser-known manufacturers.

ST is a zillion dollar company that should be hiring the talent capable of delivering product that match the features in their sales pamphlets. Integration is tricky but a company with STs deep pockets should be able to root cause or at least help troubleshoot an issue, not ask for a fix like some nepotism hire.

They should also be hiring people that can write clearly in their datasheets, but here we are, so...

I'm not an ST fanboy and they're not a vendor I use, but they are very popular in the 32-bit Cortex-M space, so they're clearly doing something right. Meanwhile, companies like Microchip that put effort into accessible documentation and tooling are getting table scraps.
