This is my ever-evolving library (not only) for AVR programming. |

When I'm done with a project, I copy the current library to the project, so it doesn't break when I do further improvements. |

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. |

It's implemented as macros to avoid overhead when passing values, and to |

enable driving multiple strips at once. |

To avoid bloating your code, try to reduce the number of invocations - |

compute color and then send it. |

Some seemingly random influences can ruin the communication. |

If you have enough memory, consider preparing the colors in array, |

and sending this array using one of the "ws_send_XXX_array" macros. |
