The 1-Wire protocol is a proprietary protocol (Maxim/Dallas) single-wire interface, half-duplex, bidirectional, low-speed and power, long-distance serial-data communication protocol. It operates over a single data line, without clock signal. But, at least two wires are required for 1-wire bus: Data, GND. An additional wire might be necessary (Vcc), depending on powering mode. The powering modes are: parasitic (no vcc), and conventional (with vcc), as seen on figures below.
This is a step-by-step guide for porting an application from MFC to wxWidgets based on my experience in porting Hippy.

| # This is Gray Code oscillator that can be used on Lattice ECP5 devices to measure time down to around 500ps of | |
| # precision (with no manual placement!) using only two (!) slices. | |
| # | |
| # In essence how this works is that we create a self-clocking counter that runs as fast as the FPGA fabric will | |
| # allow. If we were to do this with a traditional counter, we would have to worry about propagation delay because | |
| # multiple bits change at a time. If you use gray-codes, however, only one bit is changing at any given time so | |
| # there are no issues with racing signals. | |
| # | |
| # If you drop this in a design and wire out the highest bit of the async_gray_count signal into a spectrum | |
| # analyzer, you will see a dominant frequency of about 125Mhz. In other words, we cycle through all 16 gray codes |
