Ivan Grokhotkov	dec4a868d0	examples/ulp: disable pullup on GPIO15 to reduce current ... Also increase sampling frequency in ulp_adc example and update READMEs. Fixes https://github.com/espressif/esp-idf/issues/1108	2017-11-03 18:56:31 +08:00
Ivan Grokhotkov	d2acf1ce77	sleep: add light sleep, factor out APIs common for deep/light sleep	2017-09-01 10:36:14 +08:00
Ivan Grokhotkov	3c583a7655	sdkconfig: set CONFIG_ESP32_DEEP_SLEEP_WAKEUP_DELAY=2000 by default ... To increase the chances that the examples work out of the box, this change is raising the default deep sleep wakeup delay to 1ms. If GPIO15 is low at startup, ROM code takes less time to execute (because no logging is performed), so more time may be needed to allow flash chip to become ready.	2017-05-25 10:51:39 +08:00
