I am using the SPI device driver beta version #3. I need to change the baud rate but cannot figure out for the life of me how to do it. I found the IOCTL_SPI_SET_SPEED command, but no matter what I put into lpInBuffer I still get the same baud rate coming out. The function also returns true whenever I put in 4 bytes but there is no noticable change in anything. The device correctly loads and I can use the read and writefile functions just fine. The device driver came with some release notes but they said to look at the user manual to find out what all the commands mean/do. I could not find that either. Could someone please give me the mysterious manual or else tell me what I am doing wrong/ what I need to do?
Thanks a bunch.
