DSPI configuration problem

Hello,

Actually, I'm trying to make an SPI communication between SPC574S-DISP and L9960S-EVAL.

I already configured all things i can for the communication and it works, but sometimes there is an error in the RX Buffer.

I think that the craddle of this issue is the synchronisation between SDO and SCLK like the picture below:

I want that the SDO wait the middle of the high state of the SCLK to change his proper state.

How can I do that on SPC5 STUDIO ? Can I find this property on Low Level Driver Coponent ?

Thank you for your time and your answer,

Bastien

    Hello, I've just fixed this issue.

    My clock polarity was not good and globaly my SPI communication didn't fit the datasheet of the L9960S.

    Thank you,
