I;m working on a DMX device using a Teensy 3.2. I have not found a project (forum post or elsewhere) that discusses the wiring, etc. for this setup, so I figured I'd drop notes here.
Currently I have a Win10 PC running DMXControl3, an inexpensive (amazon) usb-dmx cable, an inexpensive DMX 12 led light, dmx out cable to xlr3 breakout from amazon and then into the Teensy 3.2 Serial 1 (RX1 pin 0). Using a modified version of TeensyDMX/examples/BasicReceive (mod to show rgb on 2,3,4 for the simple light.
The light works fine with DMXControl3, setting the DMX interface as "Elector USBtoDMXConverter", and defining a 7 channel device (dim, r,g,b,w, strobe, patterns)...
I had thought that a MAX485 would be needed to interface to the DMX line, but was surprised to find it isn't needed. Actually, if i wire in the Max485 i got from amazon, the moment I connect 5vdc to lights shut down.
DMXControl3: https://dmxcontrol.de/en/dmxcontrol-3
usb-dmx: https://www.amazon.com/gp/product/B07D6LNXF9
xlr3 breakout: https://www.amazon.com/gp/product/B00Q32V2JC
unused Max485 boards: https://www.amazon.com/gp/product/B00NIOLNAG
Next up will be working in control of several strips using the OctoWS2811 board and the Adafruilt NeoPixel library... or my NeoEffects variant that provides not blocking effects on multiple windows/strips. The OctoWS2811 library is not useful here as it expects all the strips have the same length, which is not the case for my next setup.
Aside from some RGBW strips and NeoPixel circles, i have some 12v Led Neon, which i have verified works with the Teensy/Octo setup if i connect the +- for strip to the 12v supply (shared ground via 2 channel bench supply) (https://www.amazon.com/gp/product/B08N9X4PC9)
