measuring board cpu/power usage

Fri Sep 19, 2014 7:59 pm

Practical question here from a embedded newbie.

What is the best way to measure CPU draw?

I am using a sleep mode, but want to compare power draw when I play around with interrupts the systick frequency?

Can any of the debuggers do this? Can the chip itself report CPU usage to the JTAG debugger or should I look into a USB power monitor or external supply with monitor?

Regards,
Adam
