7000DLE MkII PSU Voltage calibration
Posted: Fri Jan 17, 2020 5:44 pm
Hi,
I am writing some code to convert the PSU Voltage ADC readout (Protocol II, Hardware to PC, High Priority Status Packet, bytes 49-50) to actual PSU volts. I used the formula for the 200D in the Protocol II v3.8 PDF manual: Calibration constant for Supply V: V = ADC value /4095 * constant, constant = 5.0. (Could not find a formula for the 7000DLE MkII).
The results I get is about 2.05, which is wrong I am sure. More likely the formula for the 200D is way out for the 7000DLE. Can anyone please supply the right calibration constants for the PSU volts? I could use a DVM to measure it and adjust the numbers in the code but this is not likely to be right.
My thanks in advance.
