"One Octave Toy Organ"
I hope to make the "One Octave Toy Organ"
another tutorial very soon. It will be a follow up to the timers/interrupts. Currently, I have a couple other projects to tackle. The first being the write up for the PWM tutorial (since the code is already finished).
I created an audio chip that plays songs / sound FX - one note at a time. It is an expansion of the "Toy Organ" project.
I have not posted it because I didn't want to have to try and explain it. It would be a very lengthy write up and I am not sure I could explain it very well anyway.
I put the audio chip on hold for a while because I need to fully understand how to implement PWM in order to expand it's possiblities.
As for the Mario music:
I composed (programmed) several of the Mario songs on the chip and sent it to Brad for use in his LEDBoy. It is the ONE AND ONLY in existance as I have not had the chance to make any more (just yet).
A brief explanation of the "AUDIO CHIPS":
I would like to make several different audio chips for people to implement audio into their projects. The chips are called "MonoFonic Audio Chips
" and there will be several series of chips. The first being the MB01
which stands for Mario Brothers 01 (the first in the Mario Brothers series).
The chip I sent Brad is a 16-pin DIP. I made it by placing two Microchip 12f617's in one 16-pin DIP socket, then I overmolded and laser marked it.
Here is the Mario theme song:
Here is the datasheet I made to accompany the MB01:
Maybe someday I'll get around to making a tutorial on how I make the chip play songs and sounds but I fear that is a long way off!
