Sending 5 different divisions on the digital outs, and generating sine waves from a stepped value table at 3 different periods on the PWM outs. The Sine LFOs are in the range of 0 to +5V. Assembly code for the PIC18F2431 is here. Audio sample using 2 of the clock outs and the sine across a 1/4 note here.

After a long pause, the control board for the DLP VCO got printed, along with the top and bottom boards for the midi2cv unit. Now just need to wait for some back ordered blank panels and will be able to finish these two eurorack modules.
All the designs, schematics, and firmware code here: https://github.com/danielhood/dlp

I've started migrating the DLP modules to eurorack format - v2.0! First is the oscillator, two voices on one 8hp board; the knobs will likely live on a 10hp panel.
The boards came back this week, and I finally had a chance to wire one up and verify that it's alive.
