I’ve put together a HLA that is attached to a SPI analyser monitoring the comms between two chips. I encountered the problem of trying to work out where I should start a new frame in my HLA.
In my case I have CS setup and the SPI analyser knows this and it knows the mode the SPI bus is operating in. It would therefore be helpful to the developer if a “start” frame could be generated when CS changes to indicate SPI data is being sent to the device in question.
Similarly, an “end” frame would also be helpful when CS changes to deselect the device.
