ADXL355 Reset Command @I2C

Hi,

Our customer has a I2C comunication trouble.

When Reset command was written by single byte write, After the ADXL355 returns NACK, communication may become impossible. the ADXL355 does not accept commands, and it has only power supply OFF / ON for restore.

The waveform seems to have no problem. Do you have any knowledge?

 


Best regards,

Hiroshi

  • Hi,

    Tried and replicated your issue and since you only having trouble with reset command, a delay time after reset prior issuing another command via I2C might resolve communication trouble after reset. Delay time after reset should be greater than 170uS.

    Let me know if it works to further help you
