Okay guys, I searched the forum and didn't find anything relevant. Here it is:
I am planning on building an arpeggiator project based on the Yamaha YM2612 IC which was the sound chip used in the Sega Genesis console. I ordered the chips online and am waiting patiently for them to get here, and meanwhile researching as much as I can to find out what I need to do to make this project work.
My question is: which of these microcontrollers would be the best to use for this project? (These are the microcontrollers I already own, although I could buy another one if none of the ones I have will work)
*-Arduino Uno R3
-Teensy x.x* (I do not own one of these but this may be the best option based on other projects I have seen.)
I would guess that the PIC18 would be the best to use since I could program it in assembly language, but I am just now beginning to learn assembly language and C would be much easier for me. I saw a guy on YouTube who was using an Arduino Uno who built a project like this and it wouldn't run corrently, and he suspected that it was due to latency problems, so maybe the Arduino is out. Any help here is welcome.
For a little bit of background on the YM2612, it is a 6-channel FM synthesis chip with 4 operators which can be routed in 8 different configurations. It uses data exchange to write values to its internal registry to alter parameters like attack, decay, sustain, release, frequency, amplitude, etc. It is suggested to operate at a 7.67 MHz frequency and so I was planning on using an 8 MHz crystal oscillator (resonator) to provide the clock. Eventually I will integrate this project with a keyboard that outputs midi data (or maybe even bypassing midi, just using the microcontroller to control the chip manually) so I will be leaving this project open for further changes/revisions.
Also this is my first project of this type, I know it could be considered a big bite but I am here to learn. Any help is welcome, thanks guys
P.S. Here is a datasheet for the YM2612: - http://www.datasheetspdf.com/PDF/YM2612/865751/1
