boards/common/atmega: Refactoring periph_conf.h
- Moved code for periph_conf of all ATmega based boards to boards/common/atmega
- Added possibility to override config from individual board:
- Named file `periph_conf_atmega_common.h` and let this be included from
`board/$BOARD/include/periph_conf.h` to allow modifications
- Guarded individual periph configs by `#ifndef $PERIPH_NUMOF` ... `#endif`

* ATmega256RFR2
|
||||
* =============
|
||||
* The timer driver only supports the four 16-bit timers
|
||||
* (Timer1, TST, Timer3, Timer4, Timer5), so those are the Timer we can use here.
|
||||
* Timer 1, TST, PORT B5/6/7 Out, Port D4/6 In, Analog Comparator Input Capture, Output Compare Modulator, PWM
|
||||
* Timer 3, TST, PORT E3/4/5 Out, Port E/6/7 In, Input or Output Compare and PWM Output
|
||||
* Timer 4, TST, It can not be connected to any I/O Pin,
|
||||
* Timer 5, TST, It can not be connected to any I/O Pin,
|
||||
*
|
||||
* Using Atmel Timer 4 and 5 seems to be the best choice
|
||||
* Using Atmel Timer 4 as Xtimer
|
||||
* and Atmel Timer 5 as timer available for the the application seems to be the best choice,
|
||||
* as the special functions of the other timer are not lost.
|
||||
* Atmel Timer1 to be used as PWM timer for RGB LED
|
||||
*
|
||||
* ATmega328p
|
||||
* ==========
|
||||
* The timer driver only supports the 16-bit timer (Timer1)
|
||||
* so this is the only one we can use here.
|
||||
*
|
||||
* ATmega1281
|
||||
* ==========
|
||||
* The ATmega1281 has 6 timers. Timer0 and Timer2 are 8 Bit Timers,
|
||||
* Timer0 has special uses too and therefore we'll avoid using it.
|
||||
*
|
||||
* The timer driver only supports the four 16-bit timers (Timer1, Timer3,
|
||||
* Timer4, Timer5), so those are the only ones we can use here.
|
||||
*
|
||||
* ATmega1284P
|
||||
* ===========
|
||||
* The ATmega1284P has 4 timers. Timer0 and Timer2 are 8 Bit Timers.
|
||||
*
|
||||
* The timer driver only supports the two 16-bit timers (Timer1 and
|
||||
* Timer3), so those are the only ones we can use here.
|
||||
