Pressure control

Holy Pipette can control a pressure controller. Classes inherit the PressureController class, which implements three methods. Currently only Elveflow’s OB1 controller is implemented.


controller = OB1()
controller.set_pressure(25, port = 0)
pressure = controller.measure(port = 0)
controller.ramp(amplitude = -100., duration = 1., port = 0)

Pressure is mBar.

Fake pressure controller

For development purposes, a FakePressureController is implemented. It behaves as a pressure controller, except it is not connected to an actual device.
