Hi!I would like to know if there is a way to handle "automaticaly" a transmit then receive transfert using SPI and DMA ?I think using linked list should be possible, but i don't know how to configure that.. -Create a single linked list (only 1 GPDMA...

Hello !I'm using STM32U5A5 on my custom board.i would like to configure a very big buffer to store lots of ADC samples (60sec circular audio buffer)i check the GPDMA is limited to 64kBI tryed a small test using the linked list to do a small test usin...

Hi @KDJEM.1 none of both ... in fact it is a full duplex electrically, but protocol is same as a SPI RAM/EEPROM 1st part of transaction, host send the wanted address, then 2nd part host read datas from device. I thnink linked list can do the job, but...

hi @KDJEM.1 thank you but I already know these examples..In my case, I'm targeting a device that is not full duplex.In this specific setup, i need in a same chip select transfer to 1st transmit some bytes, then receive some bytes. So, I asks if it's ...

Hi @tjaekel I'm facing to the same problem.I already spent 3 days to make this OTG_HS phy working...i'm also working with a 32MHz external oscillator.But i can't get it to works (The CoreReset without ends in timeout...)i tryed your PLL settings (upd...
