Hi,
I am trying to interface the STM32F4Discovery board with an external A/D-converter. The A/D generates a GPIO interrupt as soon as the data is sampled and ready to be retrieved. After that 3 * 8 bytes h...
Posted on May 15, 2013 at 08:44Never mind my last post, I reread the documentation and believe I know what waclawek.jan meant. After every timer DMA request, the DMA_SxCR of the SPI Tx has to have EN set again. The only problem is, that the EN bit c...

Posted on May 14, 2013 at 10:06If I understand you correctly, you would start the transfer in the interrupt handler of the EXTI, right? Since I would like to have a high sampling rate of around 10 kHz, I am a bit worried that this will consume too m...
