Tool/software: Code Composer Studio
I have a piece of Java code I've written that takes program memory and parses it into another format I need.
Goal: I would like to run this Java code as a initialization script in the debugger or a pre-build command in the build step.
Question: Is this possible? Could you point me to any resources available detailing how to do this? I know the DSS runs on Java commands and I have gotten some of the functionality I need using JavaScript commands. Could anyone point me to some documentation or give a step by step guide on how this might be accomplished?
I've included my java code below. It functions as designed, but I would like to have it run as a script when the debug button is pressed, or have a script call it.
Thank you for your help making this more clear.
