Hi,I have my design using STM32H750 (which does not matter in fact it is general question) and I uses Yamaichi microSD connector hat does not have card detect pin. In single data mode, I use one of the SD-Card pins to detect card bit obviously I cann...

Hi,So I have two layer board. I have SDIO connected to SD Card and another SPI to LCD. My board uses DC-DC (Recom 3.3V) for digital power and LD1117-3.3V for analog power and both with common ground plane. No digital lines cross analog lines. Actuall...

So I have two channels configured basically with same settings. ADC1 works fine and DMA gets triggered and handled well. ADC3 DMA refuses to trigger any interrupt (not even an Error). The only difference is that ADC1 handles 14 channels while ADC3 ha...

Hi!I have tried to use I2S onn STM32H750 and DMA has no success. I can transfer without problem data by standard HAL_I2S_Transmit but HAL_I2S_Transmit_DMA results in Error callback being fired although function itself completes with HAL_OK.I2S Config...

Hi Luca @LFrei.2 Thank you so much for posting the solution of the problem. I don't know how many days of my life would be wasted without your solution. I am writing the 4 years later and ST still has not solved the problem in CubeMX.Thanks and wish ...

Technically true, but if I am not mistaken I cannot read them via GPIO if I have assigned them to SDIO DATA pins. And especially I cannot create an interrupt on that. Unless there is some hidden functionality within SDIO itself that I am not aware.

After googling I found a suggestion to enable FIFOMODE and set FIFO THRESHOLD to 3/4 for BOTH DMA channels. When setting on single channel it changed nothing while setting on BOTH channels it did the MAGIC and both channels now seem to work as expect...

Found a problem. For those not familiar with H7 series like me, the DMA operates only from D1/D2 memories and therefore its buffer needs to be allocated there.
