![]() ![]() (GPIO16 needs to be tied to RST to wake from deepSleep.) The chip can sleep for at most ESP.deepSleepMax() microseconds. ![]() mode is one of WAKE_RF_DEFAULT, WAKE_RFCAL, WAKE_NO_RFCAL, WAKE_RF_DISABLED. Code samples in the reference are released into the public domain.Some ESP-specific APIs related to deep sleep, RTC and flash memories are available in the ESP object.ĮSP.deepSleep(microseconds, mode) will put the chip into deep sleep.

If you have a datasheet or sample code that uses 8 bit address, you'll want to drop the low bit (i.e. ![]() ![]() The Wire library uses 7 bit addresses throughout. 7 bits identify the device, and the eighth bit determines if it's being written to or read from. There are both 7- and 8-bit versions of I2C addresses. On the Arduino Mega, SDA is digital pin 20 and SCL is 21. On most Arduino boards, SDA (data line) is on analog input pin 4, and SCL (clock line) is on analog input pin 5. This library allows you to communicate with I2C / TWI devices.
