This documents a USB-based curve tracer based on the PIC24FV16KM202, which is a modest 16-bit microcontroller. The board uses a PC screen OR an oscilloscope in XY mode as a display and may connect to multimeter probes for functionality.
The project has three components: hardware, firmware, and software (GUI), each with its own github repository.
I would like some help - particularly with the GUI, but it is quite functional at this point. I have tested on Windows 10 and on a Raspberry Pi 2 (Raspbian).
I took a bit to make a quick video of the curve-tracer in XY mode on an oscilloscope. I will do the same on the PC at some point. Forgive the quality, I don't have a studio and I'm certainly no producer, but I think that the idea is pretty clear.
If you would like to request a particular video, drop me a line here or at for(embed).
