Resolved! Problems with reading through SPI with DMA on STM32F407
Hi!So I configured my SPI to work with DMA and with external CS. Before my main loop I set CS high, and everytime before I initialize communication on SPI with DMA i set CS low. Then, after communication is done I go to interrupt on that event and se...
