The analog reading of our position in a single slot is an "absolute" position, not relative (like a standard quadrature encoder). Just being able to find position inside each slot doesn't tell us which slot we are in. With Single Track Grey Codes we can provide an absolute position to a single slot.

The STGC Explorer shows the know working codes, helps to validate possible new codes, visualizes the sequence and sensor position, and then produces the C code to decode the readings.

Single Track Grey Codes would allow us to know that with only one extra track. A new file has been added which incorporates this ability. It needs to be merged into the main file and holes for the sensors added to the support plate.
