How to Find Peak Current

Hi,

I am working CY8CKIT-001 DVK with CY8C55 Family processor module.In this how can we find the peak current, average current,taken by the board.

A quick and dirty method is with a DSO and a 1 ohm resistor in power lead.

Set DSO up for infinite persistance, and look at V drop across R, that will give you peak.

Now set DSO up to average its input channels, and look again at drop across R.

Regards, Dana.
