rvm_valve_control

Python driver for the Advanced Microfluidics OEM AVM rotary valve. This driver might also work with the Elveflow microfluidic distribution valve (MUX) which internally uses the same hardware.

Usage

Just clone this repo and create a virtualenv which fulfils the requirements from requirements.txt.

API documentation can be found at: https://tnaegele.github.io/rvm_valve

Example code:

import rvm_valve
import time

with rvm_valve.rvm_valve('COM7') as valve:
    time.sleep(3)
    valve.home()
    time.sleep(3)
    valve.move(5)
    time.sleep(3)
    valve.move(4,direction=1)

Todo

• add proper handling of responses from valve with method _handle_reply()
• make get_valve_position() method functional
• test whether the driver works with Elveflows MUX
• write port autodetection function
