Hello ST,is there a document showing identical peripherals between STM32 MCUs / MPUs / types / families ?It would be really helpful before switching to another MCU / MPU to have an overview.Especially for the non-HAL users.Best would be evaluations l...

Heyho,I'm using the H733 (custom board) / H735 (eval kit) with Infineon's HyperRAM S70KL1281 / S70KL1282 at 100 MHz for some time now, all working great, except for one thing that is very annoying:the data throughput from / to HyperRAM seems to depen...

Heyho,using all SAI blocks on H723 / H733 / H735 with stereo audio ADCs via DMA, working smoothly as long as both channels are used.Now I wanted to implement turning off single channels, and I thought I could do that with the SAI / DMA settings.I jus...

Heyho,I'm using a H733 with both SAI 1 and SAI 4 with SAI 1 as I2S clock master to get 8 synced audio channels.Audio clock comes from I2SCKIN, this is used for SAIs and I2S.Problem: because of the fixed oversampling ratio (256 or 512) of the SAI, I h...

Quick question concerning L0 internal EEPROM...From RM0377, page 79:Write to data EEPROM...DescriptionThis operation aims at writing a word or a part of a word in the data EEPROM. The usermust write the right value at the right address and with the r...

Dudes...You will have to understand lwIP and the MCU with its ETH peripheral anyway, so it's gonna be not much more work than as if the H5 would support lwIP.Check Piranha's post above: H5 and H7 seem to have the same ETH peripheral, so as a start cr...

Bad resolution... too much guessing.Are all the SMPS components correctly installed?Have you set the source code accordingly (SMPS / LDO)?"benchtop power supply" - is there some on-board voltage regulator in-between?I'd never do that without, because...

"Migration" guide, that's the word I was missing while searching, thanks @Andrew Neil !Anyway, a big and more simplistic overview would be great.

Thanks for the info!Very interesting, why's that so? Any internal interference between SMPS and CPU at that clock rate?@SofLit
