# originally written for ePC Article 165 Mak Pi ADC
# MakPiADC board works on 2021FJun14
# CD0 is ADC0
# Pot is ADC1
#CDS0 & pot work if SW2 & SW3 are on

# modified (ver B) for ePC Article 180 RAPasc using ixProbe by D@CC
# to read pico ADC0 with ADC ixProbe attenuated by 9
# to be used with the INA219 to measure the Tx and Rx signals of a USB connector
#    refer to ePC Article 146 for more INA219 info

#output is ADC0:(3.24738+1654827017.000j)  #ADC0: 3v3
#   Unix Time:1654827017 is Thu Jun 09 2022 22:10:17 UTC-0400 (EDST)
# ixProbe sensing pico pin 35 ADCref (atten:9)
#         green   pico pin 33 GND
#         yellow  pico pin 31 ADC0
