Change code, compile it, flash it to hardware. Measure the results, draw your conclusions. Change code again, compile, flash. And so on and so forth. If you adjust parameters in an embedded system, you probably know this typical process all too well. And how much time it costs you. But there is a way to save a lot of time per run: By making the changes directly in the embedded system. Without compiling and flashing. How to do that? We would like to show you in our short presentation.
