Fix PIO count (#211) 
Works fine currently for low frequency, breaks down at higher frequency e.g. 1MHz

Chased down with a scope to the 3 extra cycles needed for wait+1; mov; jmp
so account for these in demo program

PIO Quadrature fixes (#195) 
* Enable internal pullup on B-pin.

* pio_gpio_init is not needed for input pins.

Update pio/ir_nec/README.adoc file links (#183) 
The "List of Files" now links (only) to files, not to directories (which prevented this example being included in the C SDK databook)

This should make using the WS2812 examples a bit easier. (#84) 
* This should make using the WS2812 examples a bit easier.
Moved parameters to the top as defines:
- Number of LEDs in your NeoPixel/WS2812 strip/ring
- Flag if the LEDs are WRGB or not
Changed PIN to 2 as pin 0 is used for serial UART.

34c3ade43e Fix pio_blink frequency calculation 
Added missing parenthesis around the divisor. Verified using a logic analyzer and also in simulation:

4f64f3af80 Prevent extra bit transition at end of data 
The initial bit transition would be set even if the queue stalled.
The state machine still takes 16 cycles per bit
The next bit starts on state 1 and 9 instead of 0 and 8 so the timing is the same as before
