Hi,

I am using MMA68XX 100g Accelerometer for my testing.I am able to read the x and y axis through SPI.

I have enabled the signed data for X and Y axis. Sometimes the acceleration read response received over SPI  is "512". 

Is this value indicates an error?

how to check the error code status for SPI Acceleration request operation?

In Datasheet it is mentioned as error status would be returned on the next command passed to SPI.is this correct?

Also how to differentiate internal,spi miso error and other errors?

 

In Data sheet it is mentioned to convert the acceleration "10-bit data" to "Gravity" it need to be multiplied by sensitivity.

Is this correct? or do i have to handle additional calculation for converting "Signed Raw data" to "Gravity" ?
