Current sensing for FET-based sensor (IV-measurement, current logging)

./embedded_arduino

Code for Arduino microcontroller.

./scheme

Electrical scheme of the device

./src

Source code for a control program. Made using Codeblocks-20.03 / MinGW-W64-builds-4.3.5 (GCC 8.1.0) / wxWidgets-3.1.5 / wxMathPlot. Tested both in GCC 8.1.0 and 13.2.0. Also can be compiled with the makefile. Control program current_sensing.exe needs wxmsw315u_gcc_custom.dll.

Known bugs:

• Control program crashes during connection to a com port in release mode with O2 optimization and works well with O1. Can't find the reason yet, but the release program with O2 optimization works from CodeBlock.
