Hi everyone, I made a lot of progress since the last log. I worked on the Curve tracer like almost every day around 2-3 hours.

It is more complex then I thought in the past, it will be. Now it is sort of working, with some function.

What is working:

1. I can change the voltage range between around 40Vpp - 0.5Vpp in 25 steps.
2. I can change the frequency between 170Hz and 1.1kHz in 6 steps.
3. It is working from the main now, but if I want I can program the microcontroller at the same time.

What does not work yet:

1. I can use only one resistance range at this moment, but I am working on it. It will have 15 resistance range at the end.
2. The automatic voltage level stabiliser, which will adjust the lines to the maximum screen size, when you change the voltage range.
3. I need to finnish the main sreen (the big one).
4. I have to fix some bug.
5. The alternating mode is not finnished yet. (second channel)
6. And some little stuff.

And the video ;)
