Specify which peripherals you want to keep running during sleep. If you are worried about the sleep mode to be too “shallow” and not saveĮnough energy, note that the parameters if LowPower.idle() let you This is a good option if you want the USB link to remainĬonnected while sleeping, and you can get it with the LowPower.idle() In contrast, “Idle” is a somewhat shallow sleep: the CPU is halted but You may see here that “Power-down” is one of the deepest sleep modes:Īll clocks are disabled, the main oscillator is turned off, and onlyĪsynchronous wake-up sources are available. All these modes are described in theĭatasheet of the ATmega32U4 microcontroller, section 7: That are kept running, the peripherals that are enabled, and the This is how I wake it up again: USBDevice.attach()

LowPower.powerDown(SLEEP_120MS, ADC_OFF, BOD_OFF) The Arduino Leonardo Pro Micro utilizes an ATMega32U4 Offering even more features than a full-sized Leonardo, but at less than a third of the size. I am putting the device to sleep like so: Keyboard.end() I am using the ATMega32u4's native USB implementation, so no V-USB or anything similar. If the device goes to sleep after a few minutes of inactivity, having to reconnect after the user pressed a button causes quite a long delay between pressing the button and a reaction on the device. by waking the ATMega32u4 frequently to keep the connection alive? Or is there some not-as-deep sleep moden where the USB connection stays alive? Is there some way to keep the USB connection alive while still conserving energy? E.g. That's not really acceptable in this application, since reconnecting USB after the Arduino wakes takes pretty long (a second or two).
To reduce power consumption, I put the Arduino to sleep, but that disconnects USB.
I'm not sure if something is wrong with the board, if I have some setting wrong, or what.I am using an Arduino Pro Micro (basically a Leonardo in a smaller form factor) in a mobile application where power consumption is really important. My computer makes the 'device disconnected' sound a couple times as well. One LED blinks, then two a couple times and that's it.

12 x Digital I/Os (5 are PWM capable) Rx and Tx Hardware Serial Connections. On-Board micro-USB connector for programming. I found this link that matches the board I have, as everything else seems to use Ardunio Unos, etc. Specification: ATmega32U4 running at 5V/16MHz.
and have been following tutorials as best as I can but nothing seems to work. I have resistors, LEDs, a breadboard, wires, etc. Now that I have the actual board, I've been trying to run these blink tests that everyone does. I'm 100% new to all this, but have been trying to read up as much as I can/learn. So I recently purchased this New-Pro-Micro-ATmega32U4 Replace ATmega328 Arduino-Pro-Mini in a plan for a project I'm going to start in about a month.
