spi half duplex with dma,change tx ino rx,when finished tx process,start rx process,just set the "spe" bit of spi master(not set cstart bit),dma just starts working,and cntdr goes to zero,then rx process fail,spi report overun error.
Unfortunately I got a message that I may not attend to the workshop.I'm not interested in getting a Disco-Board for free - I can buy it by myself.Is it possible to particitpate the workshop as a "passive" member?I need no possibility to ask questions...
Hello, I have also just received a message saying I cannot attend. I do not need to get the free board (which I can by myself), Is it still possible to attend ? Thanks and best regards. Sara
If I useHAL_ADC_Start_DMA(&hadc1, (uint32_t*)uiAdcResults, ADC_NUMBER_OF_CHANNELS);it only works with up to 5 channels. With more channels there are problems with some channels in the DAM result array. For example with 7 channels, only channel 2...5 ...
Hello, I'm using QuadSPI to read/write to external flash on STM32F746NG.I used this example from ST and it's working correctly: https://github.com/STMicroelectronics/STM32CubeF7/tree/master/Projects/STM32746G-Discovery/Examples/QSPI/QSPI_ReadWrite_IT...
HAL_SPI_TransmitReceive(&hspi1,tx_sensor_data,rx_sensor_data,8,0);I want sent 8bytes, but only 2bytes sent, why?
I am working with STM32F&508-DISCO, which is said to have external Flash of size 16MB connected through QSPI. I am trying to read from it, but it is not working.I tried running this: https://github.com/STMicroelectronics/STM32CubeF7/blob/master/Proje...
We're developing for the STM32F767, primarily using the HAL. We have devices on the SPI bus which require different timing clock polarities. Re-configuring the SPI hardware through repeated calls to HAL_SPI_Init works, however, the actual hardwar...
