/**

This file provides macros for pin manipulation.
|
||||
|
||||
You can define your application pins like so:
|
||||
|
||||
// Led at PORTB, pin 1
|
||||
#define LED B,1
|
||||
|
||||
// Switch at PORTD, pin 7
|
||||
#define SW1 D,7
|
||||
|
||||
Now you can use macros from this file to wirh with the pins, eg:
|
||||
|
||||
as_output(LED);
|
||||
as_input(SW1);
|
||||
pullup_on(SW1);
|
||||
|
||||
toggle_pin(LED);
|
||||
while (pin_is_low(SW1));
|
||||
|
||||
- The macros io2XXX() can be used to get literal name of register associated with the pin.
|
||||
io2n() provides pin number.
|
||||
- The XXX_aux() macros are internal and should not be used elsewhere.
|
||||
- The io_pack() macro is used to pass pin (io) to other macro without expanding it.
|
||||
|
||||
Additionaly, there's general-purpose bit-manipulation macros (set_bit, clear_bit etc.).
|
||||
Those work with register name and pin number, not the "io" format (#define LED2 D,3).

/**

Utils for driving a WS2812 (WS2812B) RGB LED strips.
|
||||
|
||||
It's implemented as macros to avoid overhead when passing values, and to
|
||||
enable driving multiple strips at once. There is over 1us of free time between
|
||||
the colors, which can be used for some processing or color computation.
|
||||
|
||||
To avoid bloating your code, try to reduce the nuýmber of invocations -
|
||||
compute color and then send it.
