Hi, I want to use the McBSP for transmitting a variable number of bytes over SPI. The most intuitive solution would be to configure 8 bits per word, and set the number of words per frame according to the length of the message I want to send. However, this is not supported according to the datasheet.
Mind that the CS (currently controlled by FSX) needs to be pulled low continuously during the transmission.
Do you have any tips on a good way of sending multiple bytes in one frame?
