Hello, I'm trying to set up SPI communication between an MCU as master and the STM32 as slave. Data reception in the STM32 works fine, but I'm not being able to transmit data to the MCU from the STM32. I'm using the interrupt callback to read and sen...

Hi,I'm almost new to the STM32 and have the following question: I'm triggering multichannel ADC1 conversions using timer 1 and storing the readings in a buffer using the DMA. It works fine until I configure ADC2 (which doesn't support DMA) to be trig...

Thanks, now transmission works, but the function HAL_SPI_TransmitReceive_IT is not triggering HAL_SPI_RxCpltCallback nor HAL_SPI_IRQHandler do you know how can I trigger an interrupt using HAL_SPI_TransmitReceive_IT?

Changing DMA to Half Word and, consequently, the buffer data type to 16 bits did the trick. Still don't know why Thanks!

Hi, TDKThank you for the answer, The readings go from:to only by adding HAL_ADC_Start(&hadc2);the sample is triggered in the second event of a capture compare running at 20Khz, so I suppose the sample rate is 10KhzThanks in advance
