A small helper library using minimalmodbus for the popular DPSXXXX power supply modules.

Dependencies:

• minimalmodbus
• pyserial

Basic usage:

import pydps

 # connect, using port name and slave address
dps = pydps.PyDPS('COM3', 1)

# Show model
print(dps.get_model())

# Lock keys on embedded interface
dps.set_key_lock(True)

# Set voltage to 12 V
dps.set_voltage(12)

# Enable output
dps.set_output(True)

# Get current output voltage and current
print(dps.get_voltage())
print(dps.get_current())

# Get all variables at once
dat = dps.get_full_data()

# Disable output
dps.set_output(False)

# Unlock keys again
dps.set_key_lock(False)
