Thanks for the excellent reply Dave. I look forward to trying this when I am back in front of the hardware tomorrow.

Is there any way (other than assembler) to slow down the slew rate on GPIO (specifically the clock on the SPI bus). The GPIO_InitStructure.GPIO_Speed register allows for the following options GPIO_Speed_2MHz /*!< Low speed */ GPIO_Speed_25MHz /*!< Medium speed */ GPIO_Speed_50MHz /*!< Fast speed */ ...
