Hi,
I would like to hear your advice on making I2C usage low power.
From what I understand, the CPU is switching between idle and active while using I2C (correct me if I'm wrong), that in turn consumes a decent amount of power (in order of 20-30 mA depending on the module). As far as I'm concerned, the only way to achieve low current consumption during I2C communication is to use the ULP.
Are there any other tricks and tips for reducing current consumption besides using the ULP?
Many thanks
