Thanks. Great spot.

Something is not correct and it has been like this for a long time - I have reviewed the source code.

Give us a few days to sort.

PlayRTTTL is the correct command. The Help file is correct with respect to information... we just got a letter missing!

The documentation and the IDE helpers are incorrect. This will be updated in the next release. Been wrong for a long time - thank you for spotting. This means the IDE blue will not highlight the correct command. The next release will fix this.

See the attachments. These examples work. Yes... I just tried and the sound squeaked out! Yuk. I will include in the next release.

I used the Chipino Demo-Shield for these tests, see http://www.elproducts.com/demo-shield.html as this also shows the schematic that you need to use.

For more RTTTL sounds see,

Just tried this on the Xpress Board and it works perfectly, a very tinny sound but recognisable.

The only changes are the
#chip 16f1938

to read
#chip 16f18855

and
#define SWX PORTb.1

to read
#define SWX PORTa.5

and plug the buzzer into the header socket marked INT (RC2).

Cheers
Chris

If you would like to modify any of the tunes or create your own tunes here is the documentation:

You seen the 2016 GhostBuster Movie? That is tinny! It is SO poor!!!!

Anyone else seen it?

"Anyone else seen it?"

Not yet, I saw the trailer and decided I will wait untill it is out on DVD.

I generaly avoid anything that is marketed as 3D as they generaly hope the WoW factor of 3D will cover up for bad production values and plot holes.

I get a message saying the string is too large, im guessing the 16f690 doesnt have enough memory to run it

[Anobium]

If you try a smaller string does it work?
