I would like to measure the power consumption of RPi3's CPU. Is there a tool like NVidia's NVML that can give an estimation of the real-time power consumption of the Raspberry Pi 3?
I am aware of the fact that there is no tool for measuring the energy of the whole device but there might be a way of using external software tools, and maybe ARM provides something that can estimate the power usage.
I need to read the power consumption in an automated way and save it into the device. I use software to automatically tune the parameters of an application and the power consumption should be provided real time within the software.
