Here will be given detailed description how to connect basic ledMapper setup. Info about wiring and power recommended to be read.
Connect your WS281x strip to RPI:
- Data pin to one of the green pins (each is a channel selected in the app)
- Ground pin to any black marked pin
For Data+Clock strips like SK9822(currently supported), APA102, LPD8806 connect:
- Data pin to light blue pin marked DATA(2)
- Clock pin to light blue pin marked CLOCK(2)

If using static network or direct connection from computer to Raspberry, it's default static IP is "192.168.2.102" which set as default in controllers GUI if not fix it manually in IP field. Check your Network settings, your IP must be in the same subnetwork "192.168.2.X" and mask "255.255.255.0"
If RPI connected to DHCP network start Network scanner app like "Advanced IP Scanner"(WIN) or "IP Scanner"(OSX/Appstore) and find node with Raspberry Pi icon or "ledmapper" hostname.
