Hi,
For the current required for the PIC16F877A, what I did was I connected the power pins (Vdd and Vss) of the PIC to an ammeter in series to a power supply and measured the current consumed. Would this be the correct method of measuring the current required for the PIC?
The datasheet states that each PIC pin consumes current of 25mA but im getting an overall consumption of 25mA.
Would my method of calculating the current requirement of the components in my circuit be correct?
and would it be good practice to always use a 7805 regulator to the circuit or can i directly power up the board through a dc 5V adaptor.
Thank You
