Programming a PIC 16F627 for a electronic piano

[alifred]

Hi,

I want to make an electronic piano with a PIC16F627.
If someone could help me write some code for it then I would appreciate the help!

What I want:

I have a 32.768kHz crystal oscillator that I want to use as a frequency generator.
RB0-RB6 are the notes CDEFGAandB with respective frequencies 262,294,330,349,392,440,494.
Then when RB7 is held high and kept high, the notes to go up an octave to respective frequencies 524,588,660,698,784,880,988 (just double the previous ones!)

If anyone could help me with this then I will be very HAPPY!!!

I have had some limited experience with PIC's before (programming and compiling them etc.) but not the writing of any code. I can compile any code that you might give me.

Thanks

Fred

PICBASIC Pro has a SOUND command that can produce musical tones.

Hi,
I don't have PICBASIC Pro unfortunately, and it costs quite a lot!

Anyone got any ideas on some code?

Thanks

Fred

They have a free demo for upto 32 lines of code, or you could switch to the 18F1320 and Swordfish BASIC SE (free student edition)

Very easy just download gcbasic it free and u can do any thing

 

[alifred]

I am do not know any code for PIC's and I don't have any experience with writing code.

If someone could start me off with one frequency, then I could maybe have a go with some other frequencies.

Thanks

Fred

I would suggest you start with something simple like flashing an LED. PICBASIC Pros manual has plenty of examples and so does the BASIC Stamp manual (PICBASIC Pro compatible). There should be a section on music generation.

Just download and install gcbasic it has documents in word form+ tutorial for bigner plus piano example if u still require code i will write for u

Gcbasic = great cow basic

 

[blueroomelectronics]

Great Cow is good, free too. I forgot about that one.

Hi saeediqkw

Thanks for your reply.

Could you possibly write the code for one note and tell me how to change it up an octave with a button (possibly program it automatically double the frequency?) and then tell me what to change to change the frequencies.

Cheers

Fred

The answer you are looking for requires someone writing the code for you. This can take up to a few hours depending on complexity. I strongly recommend to grab a PIC manual and see how it works. Read some tutorials if you wish. Back in the day i banged my head on my desk quite a lot figuring out registers, options, intrerrupts, A/D conversions, etc. trying to make simple programs.

Good luck.

If you're not willing to take the time to learn programming PICs then why are you building the piano?

 

[alifred]

I have flowcode V3, is this any good for me to divide the frequencies?

Thanks for all of your help!!

Thanks for that - I have currently put the project on a back burner so to speak. School exams are quite time consuming!

I will hopefully continue with the project in a couple of weeks.

Thanks anyway - very helpful

This page sets off my anti virus software, perhaps I should report this post.

Well I've just watched his video oif the piano, it's really VERY impressive.

Good luck in your exams by the way!.

Hey,

BeeBop - it seems to be fine for me using AVG and Norton 2009
Nigel - Thanks very much! I also agree that that video is very impressive!

Thanks for everyones help!
