Issue with Displaying Per Unit (PU) Signals from DSP in SavvyCAN

[semrade]

Hello,

I want to use SavvyCAN to visualize the current and voltage values sent from my DSP. I’ve managed to connect and decode the CAN frames, and now I’d like to display these values on a graph to help me tune my PID controller.

However, my values are in PU (per unit), meaning their maximum is 1 or -1. When I use the “copy from DBC” feature, SavvyCAN recognizes my variables, but even after applying a scale factor of *100, the values shown in the watch graph are much higher than expected.

For reference, Ia and Ib are sine wave signals generated by my DSP.
