# 4 Channel DMX Mains Dimmer
# This is using an esp8366 (D1 Mini) sensing DMX512 Serial to a 2 channel
# mains lighting contoller (1.2A/Channel)
#
# Contoller: https://www.aliexpress.com/item/32838426377.html
# RS-485 TTL converter: https://www.aliexpress.com/item/1005005737922222.html
#
# V1.0 2025-09-06 First Rev (only tested one module, 2 channels at this stage, and incandescent)
##########################################################################################
#
# NOTES
# ------
# - Trialling with an incandescent bulb, 10% writes 26. Max value is 255 so this is 10%
# - With an incandescent, I can't see any light output below about 15%
# - Using GPIO2 as the UART TX on an ESP8266 is handy, as the onboard LED flashes with TX
# - The dimmer needs to be set to DMX mode, and given an ID of 1-999 (not standalone or dynamic)
# - there is no reason you can't run many dimmers off one ESP (limit may be in data speed lags?)
# - The dimmer is pretty smooth, and it remembers values even if no data being transmitted.
#
# System Settings on Dimmer: (onboard buttons M and < held for 2 secs)
# ------
# - Set "1 Channel" (d-1) and both channels will output the same levels. Or "2 Channel" (d-2)
# - Set reverse phase dimming/trailing edge (C-R) or Forward/Leading Edge (C-F)
# - Set minimum brightness on the dimmer, from b01-b40. Min is then 5% if b01
# - Set the 3x 8 Segment display to automatically turn off (Bon/BoF) after a period
# - pull both DE & RE high on the 485 converter to ensure data enabled (or wire to enable_pin)
#
# MAX485 Module (You could also use a MAX3485 which is 3.3V)
# ------
# MAX485 VCC -> ESP +5V
# MAX485 GND -> ESP GND
# MAX485 DE -> ESP +5V
# MAX485 RE -> Has a pullup so can leave unconnected, (or +5V)or an designated enable_pin
# MAX485 DI -> ESP32 GPIO5 or ESP8266 GPIO2
# MAX485 A -> XLR 3 (DMX +)
# MAX485 B -> XLR 2 (DMX -)
# MAX485 GND -> XLR 1 (DMX GND)
