I'm using MMA8451 - Can I permanently write settings to the sensor

[davidgroff]

I am using an Arduino Uno to write configuration settings to the MMA8451.  I have set it up to detect freefall and set interrupt pin 1.  I want to know if I can save these settings in non-volatile memory of the chip so that I don't need to re-write these to the chip every time power is reset?:

Thanks,

Hi David,

Unfortunately not. The non-volatile memory is not user accessible. The only way is to write the register configuration every time after powering up from your Atmega328 MCU.

Let me know if you have any other questions.

Regards,

Tomas
