Kees Schoenmakers's contributions
- Decode a quadrature encoder in software
- Use a D flipflop, clock it with channel A and latch the status of channel B. channel A is on the port input pin and gives interrupt, Flipflop Q is also connected to an input pin of this port. This gives a _lot_ more time for an interrupt handler to process the quadrature signals and thus a higher input frequency.
