How do I use the AUX port on the Propeller Activity Board?

ookkies

Hi, I'm new to using this and I want to be able to use the AUX port like I did through this tutorial http://learn.parallax.com/tutorials/language/propeller-c/propeller-c-simple-devices/play-wav-files for this tutorial http://learn.parallax.com/tutorials/language/propeller-c/propeller-c-simple-circuits/piezo-beep.

Is this possible?

I'm not sure what you're asking. The Activity Board is built with I/O pins 26 and 27 already connected to the A/V jack through a D/A converter and amplifier/filters. What is called the AUX port is just a connection to the A/V jack's video/microphone contact with no special circuitry attached.

What do you want to do?

I want to run a simple code like this:

#include "simpletools.h" // Include simpletools

int main() // main function
{
freqout(4, 1000, 3000); // pin, duration, frequency
}
but I'm not sure how to change the pin to connect to the A/V port

As Mike said:

your program would reflect those pins

freqout(26, 1000, 3000); // pin, duration, frequency

or

freqout(27, 1000, 3000); // pin, duration, frequency

for Left or Right output on the A/V jack.
