HOW TO TRANSFER MULTIPLE BYTES BETWEEN TWO 1769 MCUs USING SPI PROTOCOL

[abhinavdubey]

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???

Hi,

thanks for your suggestion, but I'm the same person who asked both the question and my transfer 100 bytes question is not resolved yet, when I sent multiple byte as I explained in that question, I get garbage, random sequences. pls let me know how it could be done.

thanks
