if i use a normal 9v square battery , how long can i run the atmega1284P on it with minimal components? the datasheet of this micro says 0.4mA only when active.
ok i bought LT1521CST-3.3#PBF-ND LDO
I will be running the atmega1284 at about 11Mhz so how much power it will consume? i cant find this info in datasheet.
i will add a 220uf cap on the output.
these 1.5 and 1uf capacitors should be polar?
also how can i measure the total current draw for a circuit ? i have a current meter in my multimeter and I once tried to measure the current by putting the multimeter in series on the positive rail but it blew up the micro controller together with other components on the board.
