Hello,
We are using ADXL357 alongside another SPI slave (Serial Flash).
Sensor can be accessed with no issues. However, if the ADXL is deactivated (CS manually high), the
other SPI slave can not be accessed, indicating a bus contention !.
If the ADXL is taken off completely, the other SPI slave works as expected.
Further test showed that if the CS is manually deactivated (logic high) and the SCK pin of the ADXL is removed from
the bus, the other SPI slave works too.
Our firmware test is very simple. It only reads IDs of both SPI slaves (after the problem has been narrowed down).
We expect the sensor to be fully deactivated if the CS is logic high.
We also know from the user manual that "The interface affectively autodetects the format being used, requiring no configuration control to select the format."
So, we first accessed the ADXL to read its ID (so that the internal logic knows this is SPI communication).
This is urgent matter and we need to know if this can ever happen with that sensor?
