How to use SCI module in PSIM (not to communicate between PC and DSP but between two DSP)

Sam B

Hello there,

 

I am using CCS project generated from PSIM and running it on TI Launchxl-F28379D, there I have SCIB (a module that was put in using PSIM). I want to use this SCIB to communicate between two Launchxl-F28379D but its not working.

I watched couple of videos where SCIA was being used to send a data from a PC that is running PSIM project to Launchxl-F28379D but what I want instead is have this SCIB communicating with second Launchxl-F28379D not with PC. I want to send some data from one Launchxl-F28379D to this Launchxl-F28379D that is running ccs C code project generated from PSIM. What changes that I have to do in SCI block/module of PSIM in order for this to work.

 

Thank you,

Hi Sam,

PSIM code gen for SCI comms is not meant for MCU<->MCU communication it has been specifically setup for the PC monitoring and data transfer that was in the tutorial video you saw.

For what you are trying to do you have two options, PSIM code gen supports the use of the CAN bus for this application. Or you can try Embed which is a more advanced code generation platform. CAN bus communications is likely a better method for what you are trying to do.
