Re: accelerometer adxl345 isnt working

Try using the address 0XA6, the sensor documatation indcates that the default address is 0x3A and 0xA6 when shorting J1. I belive the documentation is in error.

Once the address was changed to 0xA6 I2C communications worked. Also confirmed this by ohming the alt addrss per the Analog devices data sheet.
