C2000 F28379d SCIB

4 views (last 30 days)
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?

Hi Venkatesh Cilapur,
Thanks for your time.
  1. 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.
  2. 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.
  3. 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.

I could view the waveform on a DSO. Make sure you hook to the correct pins on the launchpad.
The Tx pin for SCI-B module is J1-4 and I could see the serial waveform on the same.

Hello Venkatesh,
To be clear, you mean that you have tried and used succesfully SCI B on my model, am I right?
