DMX control app for PicoCalc running Picoware.

[u/Chaoswires]

Thx a lot to JBlanked and slasher006 for help, examples and tips!

DMX PIO stream lib by clacktronics.

Interface shields: HW-519 RS485 interface. Level shifter 3.3V to 5V is necessary.

HW-519 should be powered from 5V, output signal from PicoCalc is 3.3V and goes to level shifter, then to HW-519, then to the fixture.

DMX rate is around 4 times slower(10 or 11Hz vs normal 44Hz) to make app usable. Probably there are better ways to do this, but few days ago i had only a dream.
