    I am pretty new to programming. I have a device which I want to connect to the RPi using SPI. I tried out the spi_devtest.c and it works. But the SPI frame of the slave device requires 24 bits. I have searched high and low and have not been able to find a solution. I tried changing the number of bits per word but that does not work. I wonder if I would have to just send 3 bytes instead of 24 bits. In that case, I don’t know how to send 3 bytes without the chip select going inactive after each word. Any help would be greatly appreciated.

    That was a quite awesome tutorial guys! Thank you. Is it possible to set digital GPIO Pins with this library (for example the CSN Pin that is recommened for SPI)?
    Greets, yvesined.
