Once more unto the breach

Final exam for this year. Mechanics.

pretty sure I’m fugged.

I’ve thought a lot more about my EPQ thing. Instead of creating a sound generator from the ground up, I’ve decided I’ll just use the YM2149F SSG. I didn’t really fancy starting from the very bottom and only being able to make crappy beeper songs which I’d have to program myself.

Instead I’ve opted to make use of whats already out there, I intend to make my circuit be able to read .YM files from and SD card (with the help of SparkFun’s OpenLog module), stream the data through a PICAXE 40x2 into the YM2149F.

I’ll have stereo AUX and a class-D amplifier on the output side, I was also thinking about having an OLED display to see the current frame that’s being stream, as well as some kind of song picker, I’ll have to play around with the Adafruit OLED a bit more before I decided to include that into the project.
