ADXL357B SPI Communication Issue

Question asked by tim43 on May 13, 2018

Hi, I cant seem to be able to read any registers on the ADXL357B. Following the SPI timing diagrams, I try to read register 0x00 for example, which should read 0xAD however I only get 0x00. 

 

In terms of the SPI, I send out SPI.transfer(0x01) to comply with the read bit. Then I send out SPI.transfer(0x00) as a dummy byte in order to read the value. That doesn't work unfortunately, what am I doing wrong? 

 

Thank you in advance.
