Currently we have full trace logging over serial. Its useful, but very slow. We are working towards the ability to set breakpoints, do tracing, variable evaluations and more. Here is a small preview.
Its not fully functional yet, but is used to display tracing. The nonsensical selection is just my debug code. The red bars at the left are the ability to set and reset breakpoints.
Hopefully by next week we will have actual functions behind this. Much of the work is already done, its just a matter of completing a few parts and hooking other parts up.
