Hello,
I'm using a Pro Micro 3.3V/8MHz board and an ADXL345 breakout board. Can you please tell me if my connections are correct?
I have: ADXL345 ------ Pro Micro
GND -------- GND
VCC & CS -------- VCC
SDA ------------ D2
SCL ------------ D3
SDO ------------- GND (USING 0X53 as device address).
Do I need to connect the INT pins to anything?
Also, dumb question: How do i decide when to use 2g, 4g, 8g & 16g. I'm currently using 2g at 10 bit resolution but I'm not sure if and when to use the other ranges.
