Library to control New Era pumps

Example usage

import time
from new_era.peristaltic_pump import PeristalticPump

pump_port = 'COM3'  # check on your own system
ne_pump = PeristalticPump(port=pump_port)
# diameter_numerator = 3
# diameter_denominator = 16
# ne_pump.set_diameter(diameter_numerator , diameter_denominator)  # set tubing inner diameter in numerator/denominator inches

ne_pump.set_rate(5)  # in ml/min
current_rate = ne_pump.get_rate() 

ne_pump.set_direction('dispense')
ne_pump.set_direction('withdraw')
ne_pump.set_direction('reverse')  # reverse the direction
current_direction = ne_pump.get_direction()

ne_pump.start()  # start the pump
time.sleep(5)
ne_pump.stop()  # stop the pump

# pump for a certain time; script will be paused until entire action is complete
pump_time = 5  # seconds
pump_direction = 'dispense'
pump_rate = current_rate
ne_pump.pump(pump_time=pump_time,
             direction=pump_direction,
             rate=pump_rate,  # not required
             )
