a) Could that spikes be related to the data transfer of the I2C Interface itself. It uses pull-ups (but these are usually in the 1 to 10 K Ohm range)
b) I have also seen in other applications during the I2C-Ack cycle a pin-driver crash generating a high current spike due to wrong timing (usually the sink is stronger and thus the software works fine since it sees the Slave-Ack).
Hi,
It could be, and for that reason, we need to setup a special testing workbench to analyze it in very depth. For that reason we kindly asking to be patient, as far it not affect the system functionality.
