Constructor
Description
The constructor creates an instance of the class. This code is usually placed at the top of your sketch before setup().
The constructor only needs to be called when you are including MAX1704X.H. If you include the file MAX17043.H or MAX17044.H the constructor has already been called in those files. You only need to use the FuelGauge object. You will need to call one of the begin() methods (for example, FuelGauge.begin()).
Syntax
MAX1704X(voltageIncrement)
Parameters
The first parameter of the constructor specifies the voltage increment (or resolution) for the built-in ADC.
voltageIncrement: float
Battery voltage is measured at the cell pin input with respect to GND over a 0 to 5.00V range for the MAX17043 and 0 to 10.00V for the MAX17044 with solutions of 1.25mV and 2.50mV, respectively.
Constants are defined for the MAX17403 and MAX17404 and can be used in the constructor.
- MAX17043_mV: 1.25 mV
- MAX17044_mV: 2.50 mV
Returns
Nothing
Example
The code snippet below shows how to create an instance of the library for a MAX17403 with 1.25 mV resolution.
MAX1704X _fuelGauge = MAX1704X(MAX17043_mV);
or
MAX1704X _fuelGauge(MAX17043_mV);
Notes
None
