More of a question: constant current mode? #7

Closed dansteingart closed 1 year ago

Awesome project. Does the standard firmware and/or standard rodeostat hardware also support galvanostatic/constant current modes?

iorodeo commented 2 years ago

Not currently. If it doesn't need to be too fast then it might be possible to do this is software using manual/direct mode with the Python API http://stuff.iorodeo.com/docs/potentiostat/getting_started.html#manual-direct-operation You could write a feedback control loop which measures the current and adjusts the output voltage to keep it constant using the get_curr and set_volt methods.

Thanks. I might try to build into the teensy firmware.
