It is possible to connect as many as adxl345 sensors together as your money allows, all explained in the datasheet.


Ok, I found it in the datasheet. http://www.analog.com/static/imported-files/data_sheets/ADXL345.pdf. It says, use OR logical gate to prevent bus traffic errors. Is the OR gate necessary, if I don't use any of the I2C buses? And what is the difference between the the 3 and 4 wire SPI connection?
