Hi,

 

I've established SPI communication between two 1769 MCUs, I send one char and slave sends back some other character. Now I want to transmit multiple bytes, when I send two characters or more at a time, at slave side I received random characters some times garbage values received, when I defined an array of chars and send it no character received at slave side.

 

SPI setting

clock at 500Khz

data bit 16

 

what would be the issue???
