Hello,I am using a STM32F427 to read and write data to EEPROM Serial 256-Kb SPICAT25256. I use LL API, and DMA full-duplex over SPI. I manage myself the Chip Slect signal.I can see with logic analyser that datas are sent and received to/from EEPROM c...

Hello,I'm using BLE_p2pClient and BLE_p2pServer programs.I had pairing request in BLE_p2pClient to have both devices bonded.Now, I want to have a fast connection between client and server; actually, the connection between client and server is about 2...

Ok. Thank you Jan.

Because I set an indicateur in the interrupt handler, and my main loop is waiting for this indicator to change.I also put a breakpoint in the interrupt handlers, for both input and output stream, but never stopped.But I can see the transfer complete ...

Hi Jan,The problem is not that the interrupt handler is called over and over, but that the interrupt handler is never called.Before activating DMA streams, interrupts are cleared:/* Clear all interrupt flags at correct offset within the register */WR...

Hi Omar,I don't understand why there would be a conflict over interrupt priorities. ST documentation never talks about conflict in interrupts. Priority levels and subpriorities are there to manage the order of execution of interrupt handler code.I ha...

Hi Omar,In the main, I have now only initialization of HAL, SystemClock, GPIO, UART8 (for logs), DMA2 and SPI4.DMA interrupt priority are set to 5 for input and output.Same behaviour: interrupt handler not called.It's a mystery to me...I'll continue ...
