Posted on November 05, 2010 at 19:28I have received a lot of help in understanding the outputs and show to use an alternate output. The beep schematic in UM0884 shous the IO as a souirce with the beeper connected to PD4 and the beeper going to ground. The spec sheet for the processor shows PD4 as a high sink output. That means I should connect the buzzer between VCC and PD4. Any help? Which do I go by?
