AVR utils library
|
||||
=================
|
||||
|
||||
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.
|
||||
|
||||
Each library file contains a large comment block explaining it's function.
|
||||
|
||||
You may need to add "c" files to your makefile for some of the library files.

You must provide a config file debo_config.h (next to your main.c)
|

|

Example:

#define DDEBO_TICKS 5

|
||||
|

#define BTN1 B,0
|

#define BTN2 B,1
|
||||
|

debo_add(BTN0); // The function returns number assigned to the pin (0, 1, ...)

||||
debo_add_rev(BTN1); // active low
|
||||
debo_register(&PINB, PB2, 0); // direct access - register, pin & invert
|
||||
|
||||
Then periodically call the tick function (perhaps in a timer interrupt):
|
||||
|
||||
debo_tick();
|
||||
|

To check if input is active, use
|

debo_get_pin(0); // state of input #0 (registered first)

as_output(LED);

as_input(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.
