Hi,

I have developed a simple code which transmists two bytes via SCI every second (12,34,12,34, etc.). It works properly (see 1.jpg with its generated code).

However a problem appears when the arrays to be sent have different lengths (see 2.jpg). According to Simulink, " the block supports variable-size signals but needs to be configured for them".

I checked the Support variable-size array box in the Model Explorer window. I also checked the Simulation/Configuration parameters/Code generation/Interface/variable-size signals.

However, it has not been fixed yet.

Any advice will be welcome.

Thank you in advanced.
