Usage

The folowing code will list all connected USB-ADC 2 devices, connect to the first device it finds and print ten values from both channels, scaled by 13.621V:

import time
from clewareADC import ClewareADC

deviceList = ClewareADC.listDevices()
if len(deviceList) < 1:
    raise Exception('No ADCs found')

for device in deviceList:
    print('Found ADC at {} with serial number {}'.format(device[0], device[1]))
print('')

with ClewareADC(13.621, deviceList[0][1]) as adc:
    print('Reading from ADC {} with 13.621V scaling:'.format(deviceList[0][1]))

    for i in range(10):
        ch0 = adc.readChannel(0)
        ch1 = adc.readChannel(1)
        print('  Ch 0: {}V, Ch 1: {}V'.format(ch0, ch1))
        time.sleep(1.00)
