From the project
Definition of the "LumaCode" signal standard with reference implementation
A small device intended to generate various LumaCode signals. Its main purpose is for developing and testing decoding/upscaling equipment.
The device is powered by 5V over a barrel jack (center positive). Use the jumper link to select a 50Hz (when jumper closed) or 60Hz (when jumper open) source. 16 different patterns can be chosen by the 16 combinations of the dip switches.
