Detailed Description

Driver for the accelerometer ADXL345 from Analog Devices using SPI.

Todo:

Use SPICallback to copy data from rx_buf when transaction is successful, instead of checking transaction status for SPITransSuccess in event loop. Problem is that in the callback we don't have a reference to the Adxl345_Spi struct.
