I'm a long-time tinkerer in using AVRs and Arduinos and such, and this is my first experience with Assembly and the 2A03 chip. After spending 2 nights of poring over technical documents, and trying different programs and banging every register on my poor 2A03 into oblivion, I found this forum.
I am trying to use a microcontroller to initialize the 2A03 and bring it into a basic "Read values from registers and output as sound". I've taken source code from other projects and uploaded it as instructions for my arduino to send to my 2A03 chip, and then wait for more instructions to arrive from buttons inputs.
In essence I am trying to create a synthesizer based around the 2A03, with the input handled by the arduino, then sent as instruction to the 2A03. Has anyone had any success trying to get the 2A03 to initialize with the help of a similarly clocked microcontroller, then patiently wait for its registers to tell it to create sound?
My reason for wanting to do this is because I am unhappy with how current trackers work. I prefer a more direct approach when composing music; I like a system where I can hear the note when I press a key. In addition a system that is purely hardware, with no PC required, is much easier to carry around and improv with onstage.
