Hi,I write my own 'void HAL_SPI_TxRxCpltCallback(SPI_HandleTypeDef *hspi)', intend to override the default weak one. But when debug, my version is never called, it always steps into the 'weak' one. I'm new to CubeIDE, the version is 1.16.0, any sugge...

Hi.I use a trigger source to trigger SPI tx/rx linked-list DMA (not circular). But have no clues how to jude if the tx/rx DMA is done. I traced the IRQ handler, it calls, the code below: /** * @brief DMA SPI transmit receive process complete c...

Hi,In STM32U5, the GPDMA has both request sources and trigger sources, what's the difference between them?Thanks.

Hi,In various ST's example .ioc files, the timer PSC, period, etc, are set with text but not numbers. This will define the numbers to macros in the code. But I can't input text in the CubeIDE. So, is this feature only supported in the standalone vers...

Hi,When using the .ioc to generate the code, it always shows:- SMPS must be enabled to reach the best consumption figure. SMPS can be enabled from the Pinout tab under PWRHow to get rid of this? Or just omit it?

Hi,I think my guess is right. After the EOT interrupt enabled, it will fire the SPI EOT IRQ, and the SPI IRQ handler will be called, then the same TxRx complete interrupt callback will be called. So, the strategy is mask the SPI's EOT interrupt, and ...

Hi,My project is created as C++ project indeed. But my 'strong' version is defined in a ".c" file. Even I convert the project to 'C' project, my strong version won't be called. And I'm sure they have same signatures.BTW: does CubeIDE support 'objdump...

Hi,Though I can register my own callback, the callback will be called only in linked-circular mode. It seems the code intends to pass the event handling to the EOT handler, then which handler callback should I use?

Hi,I want to read from an external ADC with SPI interface. As I need a stable sample interval, so I need to use a timer to kick the readings continuously. So, my plan is to use a timer to trigger a SPI RX DMA. But there is not enough information abou...
