Form R3 : PetitePirogue.com: Informatique Jul 31, 2021 · In this article, we will, as the title suggests, make the Arduino sleep, and wake it up using an interrupt. Arduino’s microcontroller, ATmega328P has 6 sleep modes, of which 5 are available with the avr/sleep.h library. Each mode has different wake-up modes and different power consumption. To do that, we’ll use the Deep Sleep mode which is the most power efficient option for ESP chip. It allows to put the ESP8266 into hibernation and saves the battery. You can wake up it at regular intervals to make measurements and publish them.Component Operation mode ----- Sleep mode1. ESP8266 170 mA ----- 10 uA2. CH340 12 mA ----- 50 uA3. While the processor itself supports very low-power modes the LM2734 Datasheet shows a typical quiescent current of 1.5mA. It is also only a step-down regulator so the Arduino Due shows a minimum operating voltage of 6V, but you'd really want to aim higher say by using 6 cells for 9V so it continues operating once the batteries are getting low. This is information on a product in full production.

The code is more or less ready and running, beside some functional bug fixes. But in rare cases the device stops working. The code was written by a passioned programmer who did all the configuration, startup himself (as it looks for me).My ultimate goal here was to get a working firmware on a samd21 board that supports sleep mode and interrupts. I was under the impression that the samd MP ports do not work without additional information and somehow in my though process I figured I could borrow the CircuitPython files as a starting place for an Arduino Zero build.I have connected a wire from the digital port 6 to the DTR port on the Arduino, which I believe is connected directly to the DTR/SLEEP_RQ pin on the XBee. According to the manual, when sleeping the XBee should ignore all input via the serial connection. But it still transmits in the periods where it is supposed to sleep.iptv links M1
