Alright, what's the max image resolution/framerate someone is going to pump out with the HSTX peripheral?

#62I 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, includin…
> STM32H7 chips can run much faster
STM32H7 tops out at 600MHz. This has 2x 300MHz at 2-3 cycles/op FP64. So maybe your applications can fit into this?

#63Is there any info on the analog capabilities compared to the RP2040?
Looks like 4 x ADC channels again, no on-board DAC

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.

#65Not off topic but a bit tangentially... How difficult would be emulating an old SRAM chip with an RP2040 or an RP2350? It's an early 80s (or older) 2048 word, 200ns access time CMOS SRAM that is used to save presets on an old Casio synth. It's not a continuous memory read, it just reads when loading the preset to memory. I feel like PIO would be perfect for that.
If it's not an academic question and you have an actual need for the SRAM, what's the p/n? I have some old parts stock and may have what you need.
Oh! Thanks!
I wanted to do a clone or two of said cartridges, that use, IIRC (I'm not in my workshop right now) a couple Hitachi HM6116FP each.
I've also seen some clones from back in the day using a CXK5864PN-15L, that's 8 kilowords, and getting 4 switchable "memory banks" out of it...

#66Earlier quoted context omitted.
1. Nobody has a wider selection of peripherals than a chip with 3 PIOs. 2. And my beef is personal - I spent months ( MONTHS of my life) debugging the damn H7, only to find a set of huge bugs in the main reason I had been trying to use it (QSPI ram support), showed it to the manufacturer, and had them do nothing. Later they came back and, without admitting i was right about the bugs, said that "another customer is se…

I don’t think the issue is QA related, ST released a chip that says it can perform X when the reality is it can not perform X.

they're complaining now because they still feel the pain now. while writing the article, they're thinking of how things would have been different on previous projects if they had had this chip, and that is digging up pain and they felt it should be expressed.
I don't know what's so unclear. Have you never had a strong opinion about someone else's stuff? Man, I have.

#69This has 2 of the 3 features (float support, faster clock) + more POI that was keeping me on ESP32. For projects that need wifi, and can tolerate the random interrupts, I'll stick with ESP32.
