sending data using I2C on Simulink

Hi there,

I'm using Nucleo-G474RE to send a bit stream over Simulink, instead of receiving 24 bits on the oscilloscope i can read only 8 bits, which are supposed to be the 8 bits in the middle that have the address of the peripheral and the status of the I2C block gives me 516 which is not on the documentation from matlab.

Simulink is a Mathworks product - nothing to do with ST - so you need to go to Mathworks for support:

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
