Hello All,I am adding parts of my code. Storing to flash is working if I DMA TIM1 CCR1 to memory and then copy from memory buffer to Flash.I assumed that writing to QSPI_DR will trigger transfer to Flash.Is it feasible to DMA to QSPI?////////////////...

Hello, I want to trigger TIM1 (Input Capture Mode) using TIM15 counter elapse (say every 1 sec). TIM1 should measure input frequency , reset counter every capture, and do one DMA of Input capture value to Memory buffer at every 1 sec (say). I tried P...

HelloI have these doubts, can you please clarify. HAL_QSPI_Command(&hqspi, &com, HAL_QSPI_TIMEOUT_DEFAULT_VALUE) -- With this I am preparing the Flash write command (QSPI CCR). QSPI_SIOO_INST_ONLY_FIRST_CMD => implies that the command need not be rep...

Hello All, I have a new question in the same context. Instead of DMA-ing the captured frequency values to internal RAM (which I was doing so far - as waclawek.jan suggested) is it possible to DMA the values towards QSPI interface on which I have a W2...

I did as waclawek.jan said, and this is working (used TIM6 instead of TIM15). Thanks again for quick response.

Thank you very much, will do this.

>Which STM32?STM32L412>use TIM15-update-triggeded DMA to transfer data from TIM1_CCRx to memory. Yes, I want something like this. But can DMA linked to TIM15 transfer TIM1_CCRx data (the peripheral is different) ? I do not find a way to do this. I do...

I want to DMA Input Capture (TIM1 CCR1) frequency values towards QSPI i/f (Single SPI Mode, W25Q128JV connected), store in Flash, DMA request being triggered by TIM6 ; on a STM32L412 based board. Need your help...

TIM1 (Input Capture Mode) should DMA one single input Capture value (direct time period measurement, counter reset at every capture) to Memory at every TIM15 counter expiry.
