Hello everyonve,
I'm using the board TI F28377S but have problems to use the serial communication with SCI Blocks. I would send the read data of an ADC to the serial port.
Here my Simulink project with configurations of serial communication:
When I try to read I have no reponse:
I have read a lot the examples about how to use SCI block but I didn't find the problem. How can I fix this?
Any help would be much appreciated.

  • Make sure the port is not used by other debugging tools
  • the data output form adc is 16 bit so you won't read it with a simple command you need to set the number of bytes to be read by the PC
  • The handshaking should be implemented for your serial communication
  • You should use buffer in both matlab and the DSP because the time of the date read from the ADC is different from the data sent by SCI.
I implemented it before with ARM M4F DSP and won't suit with your C2000 and I had to write my code for M4F. Only can be done by handshaking and buffers

Hi,
Could you please confirm from the device manager if the board is actually connected at COM port 6. We could use your model and be able to read data successfully. There is a blue LED on top left corner of the board that comes to activity when I'm running your model.
Regards, Venkatesh C
