I have setup the spi connection, and i'm testing it with a logic analyzer.It all works great. BUT, the Transfer half complete interrupts occurs before any data is transferred when i use;(HAL_SPI_TransmitReceive_DMA(&SpiHandle, (uint8_t*)aTxBuffer, (u...

Im working on stm32f103 controller which has an eeprom interfaced to it via spi.

For the spi mode CPOL = 1 and CPHA =1 does the master(stm32f103 controller)​ receives data on MISO line at the rising edge and also sends data on the MOSI line at the rising edge? Similarly for the spi mode CPOL =0 and CPHA = 0 does same happen as fo...
