04/07/17 – Updated sleepSeconds() function.03/29/18 – Fixed custom battery capacity.For backward compatibility, the SDA and SCL lines can be connected to A4 and A5 by bridging the corresponding solder jumpers on the bottom of the energyShield. The TWI is, by default, connected to the SDA and SCL pins which are available on all Arduino’s with the R3 layout.
This library communicates with these peripherals using the Arduino Wire library (TWI) and one of the Arduino’s analog inputs (A0 by default). This functionality comes from the integrated battery fuel gauge, real-time clock, solar input regulation, and voltage measurement ability (these features are not present on the energyShield 2 Basic). The energyShield 2 library provides software functions that allow the user to easily access all of the energyShield 2 Pro’s advanced functionality. EnergyShield 2 Pro Arduino Library Reference
