I have been looking high and low on the Internet for information on how to calculate the average current in an MCU-based circuit.  I have an app note from Microchip on the subject, but it only shows the battery life computation after average current is known.  Can someone please explain to me how to compute average current on an I/O pin?  As an easy example, let's say that Vdd is +4.5VDC, and the pin fires 8 40kHz square pulses through a load of 2KOhms.  Also, what is duty cycle and does it have an effect on average current?  Thanks for your help.  </BLOCKQUOTE>
