Sir,

Could you assist me in developing a code(.asm) for

tone generation with 8051/89C51 microcontroller
well would be using the 8051 development board
well th concept to generate tones of octaves
i.e port0 would be the 8(just for 1 octave)push button

[duplicate text removed]

keys as the input and port1 or port2 as o/p
i.e the amplifier circuit to speaker.....
once key is pressed and recognized its corresponding
count (audio note frequency) is given to timer section
of 8051 to give a square wave to speaker.
octaves(combination of musical notes with 8 keys[not
necessary a matrix])

program logic
1.look up table for mapping the count of audio freq's
of keys
2.key debouncing
3.key pressed then map the count frm look up table
4.give to timer section of 8051 at 12mhz to get the
o/p

I would be grateful to the earnest reply.....
