Hello,

I need to use SCIB port of the F28379d on MATLAB Simulink. I assign some pins for SCIB communication and SCIC communicaiton on the configuration and I have attached related figures. I am trying to send a data over SCI. When I use SCIA, I can send all the things. When I see SCIB or SCIC I can not see any data signal on the related pins.

How can I solve that ?

What I do wrong?

Thanks.

Hi,

Few points to verify real quick:

Hope the SCI block(Simulink block) is configured for the respective module like 'B' or 'C'.
Are you using a USB to serial converter to connect?
Also ensure the Host and Target baudrate match.

Regards,

Venkatesh C

Hi Venkatesh Cilapur,

Thanks for your time.

Yes SCI block is configured initally to SCIA and it is observed that it works well. Than I configured SCIB and observed with oscillopscopethat there is not any data signal on GPIO 18 and GPIO 19. Than I have used SCIC block and observed GPIO 56 and GPIO 139 and again did not get any data on these ports.
I am using a USB to program evaluation board. I am checking ports with an oscilloscope. Later when I manage to get signal on SCIB or SCIC, I will have a USB serial converter.
I use same baud rate with SCI A-B-C. Only A works.

Thanks. I am looking forward to get a response from you.

Have a nice day.

I have attached also related slx file.
