Hi Yara, To clarify, our F28004x SPI module is capable of data word lengths from 1 to 16 data bits. We do not support 24 bit transactions inherently. Could you explain at a higher level how you are trying to send and receive the 24-bit data? How are you planning on breaking up break up the 24-bit data, since it will take more than one transaction? Since it will be two transactions, I imagine you should also be sending them back-to-back to ensure the chipselect remains low during the complete duration. Does you code run at the moment? Are you seeing specific errors? Sorry for all the questions- j ust wanting to get an understanding of the goal here and the specific trouble spot you are having. Also, have you already referred to our SPI examples in C2000Ware? ([C2000Ware]\driverlib\f28004x\examples\spi) Best Regards, Allison
