After reading the recent postings about PIC / Stamp
microcontrollers I was wondering if there is any schemtacis and info
for digital synths based around ADC / DAC's and CPU's. These digital
systems interest me because I am a software engineer and have been
coding for a very long time...
I am not really interested in Stamp / 8051 designs as I think they
are a little long in the tooth now.
I am looking to use at least 1Mbyte of SRAM, at least 3 serial
ports (MIDI In, Midi Out+Thru, Hi Speed serial IO (115200 Baud) for a
PC link), ADC/DAC via some kind of DMA device or more probably a FIFO,
a programmable clock device (5Khz up to 44.1Khz) and the SA110 CPU
(StrongARM running at 233Mhz).
Of course one could always use an 8 bit parallel port interface
which would allow a stupidly fast PC link (1->6 MBytes Per Second).
What it really boils down to I am a software engineer not a
hardware designer. Are there any schematics of digital CPU controlled
synths on the net?? Are there any mail lists / news groups that deal
with the building of simple computers. I have yet to find anything!
