cpu/atmega_common: add support for eeprom periph interface 2018-04-03 12:57:13 +02:00			`FEATURES_PROVIDED += periph_eeprom`
cpu/atmega_common: provide gpio feature at cpu level 2019-10-17 21:42:07 +02:00			`FEATURES_PROVIDED += periph_gpio periph_gpio_irq`
eeprom: Makefile.features: reorder features They should be sorted alphabetically 2018-05-29 19:24:10 +02:00			`FEATURES_PROVIDED += periph_pm`
atmega_common: provide CPU ID for every device ATmega128RFA1/ATmega256RFR2 do not have a unique CPU ID. Use the RC oscillator callibration byte as an impromptu CPU ID and rely on bootlader constants present on all ATmega families for the remaining bytes. This way we can provide a faux CPU ID on all ATmega MCUs and typical hobbyists with no access to JTAG adapters or high voltage programmer capable of writing the user signature have a good chance that the CPU IDs of their device do not collide. 2019-10-30 23:10:30 +01:00			`FEATURES_PROVIDED += periph_cpuid`
cpu/atmega_common: add implementation for watchdog 2019-11-07 09:58:27 +01:00			`FEATURES_PROVIDED += periph_wdt`
cpu/atmega_common: Implement RTC based on TIM2 This implements a basic Real Time Clock based on TIM2. As the timer is too fast and wraps around after just 8 bits, it is not used directly. Instead TIM2 is responsible for providing a 1 Hz tick by generating an alarm every second. The current time data is kept in the `.noinit` section, so it will survive a reboot, but the clock will not be updated while the bootloader runs, so expect inaccuracies. 2020-02-18 00:08:52 +01:00
