Hi folks, I have been working modifying the arduplane code for enabling some custom functions, however I would like to test the servo movement of my custom functions before placing the board on the plane for testing. Therefore, I decided to do HIL. However, I was reading the instructions for enabling the HIL and it requires to upload the HIL SIMULATOR firmware which erases my custom code and uploads a new firmware again, is it possible to enable the HIL from the source code? What are the differences between the HIL Simulator firmware and the Arduplane V3.1.1 at the source code level?
