Mega32L External Clock
« on: February 22, 2013, 02:26:08 pm »
Hello ! I want to put an external crystal oscillator , but I'm not sure how to put it . I need only to put the oscillator terminals to pins 12 and 13 ? It's ok if I put 8 MHz Crystal ?

An 8 MHz crystal is ok, but have a look at page 26 of this: http://www.atmel.com/Images/doc2503.pdf
You need 2 capacitors to ground also.
