cpu/sam0_common: GPIO: use tamper detection to wake from Deep Sleep On samd5x only the RTC can wake the CPU from Deep Sleep (pm modes 0 & 1). The external interrupt controller is disabled, but we can use the tamper detection of the RTC. If an gpio interrupt is configured on one of the five tamper detect pins, those can be used to wake the CPU from Deep Sleep / Hibernate. 2020-05-06 00:11:29 +02:00			`ifneq (,$(filter periph_gpio_tamper_wake,$(USEMODULE)))`

cpu/sam0_common/periph/uart: implement buffered write Implement interrupt based uart_write() using a tsrb for the TX buffer. To enable it, add USEMODULE += periph_uart_nonblocking to your Makefile. 2019-08-20 20:52:07 +02:00			`include $(RIOTCPU)/sam0_common/Makefile.dep`
