Hi Guys,
I have a simple SPI program running between two devices which mostly works fine.
But I have found that sometimes when powering on the receiver, it is as though it loses the initial sync and receives the wrong value from the master (using a loop from the master just to send the number '90'). Like as if it has a few bits still in the buffer from an initial half communication.
Is there a flush command or something that needs to be done when CS goes high, to clear out random bits in the SPI receive buffer, to ensure we are working with a blank receive buffer?
Many thanks!![:)]( "Smile")
