Hello there.. im new here... hope im not double posting..
Im building my first pic project for my micro-controllers course.. a 1-D ping pong game .. using the pic18f452
Anyhow.. i need to put some tones using a frequency generator (CCP1).. and i know how to do so.. but can someone help me find melodies in frequency?!..
like RTTL or sumthin i dunno...
Any melody would be fine... just DONT throw britney spears tracks at me..
 
This is for the 16F series, but you may find it helpful?, I've used it on a 16F628 and it works fine (I actually dis-assembled the HEX file and modified it in assembler, as I don't do C).



Just remembered! - I also used it on a 12F675, makes a nice little 8 pin 'tune playing' chip, and I altered the code to use the internal 4MHz oscillator.
 
i already checked the page u gave me and didnt do anythin for me as i dont do C neither... BUT...
Dis-assembled?... this thing really exists? .. can u lead me to a good disassembler plz?... does MPlab include one?!

MPLAB does (apparently) contain a simple dis-assembler, but I use my programmer software WinPicProg which works rather better.

If I can find the assembler code tonight at home I'll post it for you!.

OK, I couldn't find my original source, it's on an old hard drive which isn't connnected at the moment - but I've run the HEX file through my dis-assembler, and here's the assembler it produces.

This is just as the disassembler creates it, it should assemble fine with MPASM, the versions I modified previously were tidied up (C produces pretty horrible assembler!) and commented.
