Make a constant for the precision of reading. about circuitpython_ina3221

(I hit return accidentally and it sent off the title!)
Suggest
Define constants for
MIN_SHUNT_VOLTAGE = const(0.00004)
MIN_BUS_VOLTAGE = const(0.008)

and use in code

This allows calling methods to compare values against the resolution available if needed

Like your version of the library. Much nicer.

Thanks John

Hi @jmfloyd

I've added the 2 constants as:

# General constants
C_BUS_ADC_LSB                    = const(0.008)      # VBus ADC LSB is 8mV
C_SHUNT_ADC_LSB                  = const(0.00004)    # VShunt ADC LSB is 40µV

for both lite and full in this branch : https://github.com/barbudor/CircuitPython_INA3221/tree/pr_add_LSB_constants
Are you using lite or full ?

I don't have the time to setup a test platform, so could you please test and report back that I haven't broken anything ?

If this is ok, I will merge in the main branch.

Thanks for the suggestion.

I have tested your changes and working as expected
