I am trying to do SPI communication using XMC4800-196 and DAVE SPI-APPs.
I encountered a Timing Problem since the MOSI data is exactly syncronous to the SCLK clock (should Change state 1/2 clock earlier!). The Shift clock delaying in the SPI-Config Dialog has no effect! The SPI slave requires SCLK state low on idle, and MOSI must be stabe on rising edge of SCLK!
Any Suggestion how to get around?
Thanks

In the APP, go to adv settings, then the field control has "Clock Settings". Here you select the SPI Modes.
The Delay Settings are something else entirly - you shouldn't change them unless understanding them (leave at 1).
Then don't forget to click the "generate code" button (the notepad symbol with red pen on it).
