The SPI will not receive one byte and then 4 more bits, or at least I cannot figure out how to do it. Is there some way to do this? I can transmit and receive DS1626 data by bit-banging on PTT pins, but I'd like to use the SPI. I've tried to use the routines from both Professor Cady's and Professor Valvano's texts, but to no avail.
Can anyone help?
