FDC2114: I2C write

Hi E2E,

Good day!

Just would like to know what will happen if you send more than 2 data frames (eg. 4 data frames) during write sequence? Will it ignores the last 2 data frames?

Best regards,

Franz

  • Hi,

    It is required to issue a stop command after sending 2 data frames for writing using I2C. If you are planning to issue a stop command after 2 data frames and send 2 more data frames after that, then the last 2 data frames will be ignored. Is there any reason you want to send 4 data frames instead of 2? 

    Regards

    Sharath.

    Hi Sharath,

    Thank you for your response.

    My customer is thinking of sending a sequence of data frames, similar to an I2C burst write on other devices. Is this possible?

    Best regards,

    Franz

    Hi Franz,

    Unfortunately, this device does not support I2C burst write operation.
