Hi All,
I need to design a power supply for my pic circuit and i need to know how much current my total circuit uses as i am going to use a DC Plugpack to power the circuit. I need to measure the total current required so i can get the required current rating on the DC plugpack.
I'm not sure where to measure in the circuit to give me the total current. Would i have to measure each of the inputs and outputs on the PIC and then add all the current readings up in series?
The schematic is a xps document so i cant attach it at the moment. Its got some leds, an lcd screen and a couple of piezo buzzers on the outputs.
Thanks
