Since you want to change the frequency with press of a button, what frequency range you had in mind?

In flowcode 3 examples (TUT_24.FCF found in Flowcode V3/Examples directory) there is a basic way to produce tones.
It will get you started and will work with V4.

Hi everybody!

ThankΒ΄s for your respons. I will try TUT24.

This I mean by press a buttum is, when I press on an Input I get a sound on 1750hz on an output. But to change the tone I would do it in the program. Its only an examble I need. Is it possible to make the tone without Interrupt?

Best regard

Hello

Yes its possible to make a tone without an interrupt however if you do not use an interrupt then all your program will be able to do is to make the tone.

eg

while 1
{
output 1
delay
output 0
delay
}

By changing the length of the delays you change the frequency of the output tone.

You may be able to fit a bit more functionality into the loop but the more you add the less control over the tone you will have. Eg. anything that blocks the program for any length of time will cause problems.
