Posted on August 18, 2012 at 00:19I am trying to receive data over full duplex SPI but STM32 does not line up clock and data if I configure in SPI_CPHA_2Edge. However if I configure in SPI_CPHA_1Edge, everything works fine. My slave however sends d...
Posted on August 16, 2012 at 16:27Hi,I am looking for recommendations as to how best to deal with SPI transactions where the SPI word length is greater than 16 bits.I intend to use 64 bit transactions from the host PC to my stm32 board. Therefore, I...
