Laurent Navet	4c9c3ab7d6	cpu/atmega_common: fix timer_set_absolute return code ... according to timer documentation, timer_set and timer_set_absolute should return 1 on succes, not 0.	2016-09-10 00:12:39 +02:00
kYc0o	5e3747ea8b	Merge pull request #5590 from mali/atmega_common ... cpu/atmega_common: improve to add smaller atmega MCUs.	2016-08-31 18:29:53 +02:00
Jon Thacker	0cc65db1b2	cpu/atmega_common: Add support for double speed baud generator ... * Add support for U2X switch to double transmission speed * Provides lower error rates when needed * Add support for static baud rate calculation, reduces computation by 10x * adds support for statically enabling double speed baud	2016-08-20 08:49:30 -05:00
Laurent Navet	eed73beaa1	cpu/atmega_common: prepare for atmega328p inclusion ... use generic avr/libc definition for conditionnal compilation. eg: use #ifdef(PORTG) or #ifdef(TIMER_0_ISRC) instead of #ifdef(Atmega328p) This is more generic and simplify future boards support.	2016-08-20 12:23:48 +02:00
Laurent Navet	2cd918a07a	atmega_common: abstract Power Reduction Register ... PR Register is PRR0 on atmega2560 and atmega1281 but PRR on atmega328p. this abstracts as atmega Power Reduction Register as MEGA_PRR.	2016-08-20 12:21:32 +02:00
Jon Thacker	2aec999900	cpu/atmega_common: generalize register/peripheral definitions ... Makes AVR register definitions dependent on what avr-libc defines for a given MCU, rather then duplicating that effort here. Definitions done in this way are based on functionality provided, rather than a specific MCU device.	2016-07-08 10:52:22 -05:00
kYc0o	17c78e70e2	cpu/atmega_common: add common atmega CPU code to atmega_common	2016-06-22 14:25:10 +02:00
