资源说明：Real-Time Systems project which tied a PlayStation controller and VFD to a MOS8580 SID chip using an Atmel ATMega8L
All About The Goods: ================================ This was a fun project I did for a Real-Time Systems course at the U of Manitoba. Plays music on a Commodore 64 SID chip using a PlayStation(2) controller. What it can do so far: ----------------------- Configure voice #1 of the SID chip. Such enticing configurables as: - Triangle, Sawtooth, Square, Random waveforms. - ADSR Envelope (http://en.wikipedia.org/wiki/Synthesizer#ADSR_envelope) - Volume! Configure screen: - Brightness! All four levels of it. Play notes!: - Shoulder buttons for octave & sharp selection, face buttons for notes. - Even some that don't exist! It's like the X-Files had an episode about synthesizers. Save settings to EEPROM: - That's definitely working. What I want it to do: (future features) ----------------------- Storage: - Save my silly songs to an SD card. - Replay. - Save to PC. Have head-to-head-to-head jamming: - Have two more controllers for the other two voices. - Everyting's better with friends! Quick instrument switching: - Maybe just between voices at first. - Cool to have everyone be able to switch quickly / independantly. Bring in external source: - Pass through voice 3/filter Get some of the nuttier SID stuff in there: - Low-pass / high pass filters. - Freq cuttoffs. - Freq pulse width adjust. - Resonance. - Sync voices (makes interesting effects so I hear). - Ring modulation between multiple voices (for solo play, also for effects). Get random effects ideas from the demoscene - Allow quick on / off from the circle button. - Guitar peddle type effects (wah-wah, etc). - Great excuse to finally use those analog sticks! YES!
