Presently micro-OSC supports the PIC18F2455, PIC18F4550, and PIC18F4553.

We like the USB-enabled PIC32 processor for the next uOSC port. It has more memory, is much faster and has considerably more digital and analog pins. The 16 ADC channels are 10-bit though not 12-bit as in the PIC18F4553.

We are considering a port of uOSC to the ARM and indeed parts of uOSC are being intregrated into the Make Controller from Making Things.
