Recenlty I have started using MMA6813BKW dual axis SPI sensor. I need to calculate the g-value out of this sensor and I am trying to configure it as below.
I have configured the sensor according to the details given in the data sheet page num: 45, sec: 4.1. I requested the raw acceleration data out from x-axis, unsigned and with odd parity. based on the above configuration I send the SPI MOSI
command as 0x3004 (I send only this command 4times, no other configuration made) as a response MISO I am getting only 0x0E00, even if I move the sensor in all directions.
Can you please support me on the following topics,
Thanks in advance.
