[sdiy] Roland DCOs

[rob]

Hi Tom 
For a DCO I am planning to use a Phase Accumulator chip (Analog Devices
AD9833) to drive a simple wave table, with a PIC reading control voltages
and programming the Phase Accumulator frequency..in fact the AD9833 will
create 10-bit triangle, sine and sqaure, but I'm not sure about it running
slow at 20k rather than 12.5MHz...more fun to run through a wavtable and
having all that waveform fun...

Regards
Rob
