Using two ADXL345's

[jlboygenius]

Looks like the library is hard coded to use 0x53, but documentation says you can use 2 of them..
Can this be passed as a variable during initialization rather than hard coded?

Hi @jlboygenius,

The class constructor does take an optional argument for the slave address. In ADXL345.h, you'll find the following lines:

#define ADXL345_ADDRESS_ALT_LOW     0x53 // alt address pin low (GND)
#define ADXL345_ADDRESS_ALT_HIGH    0x1D // alt address pin high (VCC)
#define ADXL345_DEFAULT_ADDRESS     ADXL345_ADDRESS_ALT_LOW

So you can actually instantiate the object like this:

ADXL345 accel(ADXL345_ADDRESS_ALT_HIGH);

...or simply:

ADXL345 accel(0x1D);

...and it should work that way.
