1. Flash

Install flash tool: pip2 install esptool

Flash ArtNetNode:

sudo python2.7 esptool.py --port PORT(e.g /dev/ttyUSB0) write_flash 0x00000 ESP8266_ArtNetNode_DMX_1.2.0.bin

2. Setup Arduino IDE

3. Download libraries

Requires: ESP8266 Core for Arduino: https://github.com/esp8266/Arduino/ ESP-Dmx library: https://github.com/Rickgg/ESP-Dmx E1.31 library: https://github.com/forkineye/E131 Adafruit-PWM-Servo-Driver-Library: https://github.com/adafruit/Adafruit-PWM-Servo-Driver-Library

4. Connect ESP8266 - PCA9685

GPIO5 - SCL GPIO4 - SDA Gnd - Gnd 3V3 - VCC

5. Program ESP8266

Upload ESP8266_ArtNetNode_DMX.ino to ESP8266 using Arduino IDE

6. Connect to WiFi Hotspot

When you first start the device, It will attempt to connect to the WiFi network defaultSSID (which I doubt exists). If it can't connect within 30 seconds, it will start a hotspot. The hotspot is nodeName_XXXX (nodeName by default is artNetNode and XXXX is a random number). Connect to this hotspot using the password artNodeXXXX (XXXX is the number from the hotspot SSID).

Go to 192.168.4.1 with web browser

7. Download DMX controller software:
