Device Info

All megaAVR devices with a Timer/Counter module can be used.

Setup

The following connections are required on STK600 for this example:

• For LED output, connect PORTD pin header to LED pin header with a 10-pin cable.
• For 32KHz clock, connect a wire between 32KHz and TOSC2 on the AUX pin header.

Description of the example

The example will configure a tick speed of 1024 Hz and use two different periodic timeouts to toggle two different LEDs. One will toggle at 1Hz and the other at 1/3Hz.

Compilation Info

This software was written for the GNU GCC for AVR. Other compilers may or may not work.
