Picaxe 18X: Waveform to Pitch Mapping

A fun little setup. The output from ProTools is connected to an analogue input of the Picaxe. The Picaxe simply has a little program on it that says something like "take the voltage from the analogue in pin, and use that as the pitch of a beepy note". ProTools is running a signal generator RTAS plugin.

You can see the code here:

im working on a super low-quality 'scanner' using LEDs and a photoresistor hooked up to a picaxe chip that reads the resistance from the photoresistor and sends the data into a computer through a hacked keyboard.

black and white only, about 2-4 DPI resolution.

Wow, that sounds really cool! I would appreciate it if you let me know when you finish it, and how it all pans out.

Cheers!

Cool video.

is this using the analoge to digital converters to put the sound genorated by protools through the picaxe and into a speaker, or is there more going on here that im missing?

re: prfctday.

here in canada, i get my picaxe chips from hvwtech, a vancouver based company. the 18X is about $10 Canadian dollars a peice.

[littlescale]

Yeah, that's pretty much it. off the top of my head: readADC 0,b0; sound 1,(b1,1); or something similar. just a test, to see the results, is all.

What are you up to with the picaxe?

[prfctday]

I just saw some picaxe 8, 18 and 28 online for about £15 average. I want one but would have no idea what it's for or how to use it! Is it easy?

[littlescale]

Yes! It's very easy to use, at least I think so. It takes like 20-30 mins to read the manuals, and then you are off. If you are thinking of getting into microcontrollers, the picaxe chips are the way to go. However, 15GBP seems a tad expensive. I paid AU$45 for an 18x (the best 18 pin chip) + software, cable, project board. Email me if you have any more questions!

This is a very "past" video. =p

[gordoncraig410]

Your video is a favorite on Seychelles

[littlescale]

yeah, i know. it's got a nice glitchy / randomness to it at points.

[prfctday]

Interesting. Sounds like 1960s science fiction film sound effects. cool.
