Dont know what kinda bootloader it has. Also, did I understand it right that this is a pure software Watchdog without external ICs like a ? Thx Thorsten. AWOL Guest. But can I use it with my Mega board or is that not compatible? Quote from: currymuetze on Jul 01,pm. Jimxbob correctly pointed out to me a few oversights of mine so FYI: Quote. Currently the mega will lock up and need to be powered down if you use the watchdog timer. The bootloader on it has the same problem the older bootloaders had.

You might mention that in the file just to avoid the mails and questions that may be coming your way. As the my prayer request above may have indicated, I've been avoiding the wdt on the mega board because the bootloader doesn't initialize it properly. The board would hang up in a loop, requiring a power cycle to recover. That meant that I had to fake a watchdog using timer 3 on the board.

That was not a very satisfactory solution especially since the watchdog should be able to do this job. Well, your description got me to thinking and I came up with a solution that uses the watchdog AND allows me to have a much longer watchdog timer.

This is exactly the solution I needed to free up timer three and put the job back on the watchdog like it should be. I still can't use WDE, but that problem is easy to work around.

Here's the code if you want to include it at some point or just to expand your example. Nice job.

What is the watchdog and how to use it

Thanks very much for the feedback draythomp- Ive only got UNOs sitting on my desktop at home which is why I haven't encountered any of the problems you guys how to break the egg on make money app bringing up. I may update the tutorial at some stage or another but for now the forum thread is short enough for someone to be able to skim and make changes at a glance - great timer work-around!

I presume you only added the Serial in the WDT interrupt to debug and get some sort of feedback - Ive never encountered any problems but just be aware if serial happened to be the function that caused the board to malfunction and prompt a WDT interrupt, It may cause the interrupt to hang if you bring up serial in the interrupt and you will never get around to resetting the board.

Thanks again for the feedback! Such contributions are what make forums such great mediums. Any examples codes for this?By Dave Lieber.

Twenty years later, I still remember the parade of nincompoops masquerading as air conditioning repair techs who marched through my first Texas home without any real idea how to give me what I wanted. Cool air. I called them Moe, Larry and Curly. Their company was Frymire Services of Dallas, one of the older, better known AC, heating and plumbing companies.

Their distinctive yellow and black trucks were seen all over town.

Frymire did the installation work for new homes in my subdivision. In my case, as in many others, they had to come back again and again to make adjustments. They made two dozen visits to my place. After three years of torture, I still didn't know what to do, I didn't know my rights as a consumer.

I didn't know how to fix this. My neighbor, Eric Easton, knew. At a block party, he told us the story of his bout with Frymire. His house wouldn't cool below 90 degrees, and Moe, Larry and Curly were stumped. Eric taught me the proper procedures to exact revenge, er, get my system working properly. He showed me a state law called the Residential Construction Liability Act that lays out the proper procedures for warning a builder of deficiencies — and then filing a small claims court lawsuit.

His house was cool. I didn't know any of this. I was a decade away from becoming The Watchdog. But in a sense, my consumer awareness was born during this escapade. I never had to fight a company before. For the first time, I had to learn how to take on a corporation. This was Every repair tech sent by Frymire, from their best repairman to their top supervisors, offered a different solution to the same problem.View Cart Checkout.

When we enable the watchdog, during normal operation, we need to reset it. But watchdog timer can also be used like a timer that wakeup the microcontroller after a certain time, by using its interrupt. So we can put to sleep the microcontroller, save power energy, and then wake up the microcontroller with the watchdog set to certain time. If we are using a battery, when we turn off the LED and then we wait for 1 sec, we only waste energy.

Take a look of the Datasheet of the Attiny When the micro is in active mode — while we wait and the LED is turned off — it consumes uA. Otherwise, if we put in sleep the microcontroller — specifically in power-down mode — it only consumes 0. If the micro is in standby who wake up it? We need to push some buttons to fire an interrupt? Well, we have created the function waitSleep where we can indicate how many seconds we want to sleep.

We are using this function instead of the delay function. The waitSleep function counts the number how seconds we want to sleep. This because the watchdog timer can be set in different timing. In this case we have set the watchdog to fire every 1 sec. So, every second the waitSleep function call the goSleep function that set the watchdog, disable all the unnecessary peripherals an go to sleep. If the microcontroller goes to sleep for the seconds that we have set, the code return to turn ON the LED.

Every time we have a watchdog interrupt, this bit is set to 1 by the microcontroller. So we need to clear it to make the interrupt works again. Your email address will not be published.

Take a look of the Datasheet of the Attiny84 What my eyes see??? Really 0. Well, now the question is: If the micro is in standby who wake up it?

We can use the watchdog timer interrupt to wake up the microcontroller after certain time! Well, but how we set the watchdog and, more important, how we set its timer value?

We need to read the Datasheet. Well, know we can use WD to save energy. Share Tweet Share. Submit a Comment Cancel reply Your email address will not be published. Products KeyChainino V3 Rated 5.

So, the main program needs to periodically reset the watchdog timer, to prevent the reset of the CPU and keep working normally. In those locking cases, the watchdog is not reset and, when it expires, resets the system. This concept is of extreme importance, specially in microcontrollers, which may be affected by environmental conditions such as electrical noise, which can cause hardware malfunction that locks the execution.

ESP8266: Watchdog functions

The ESP has 2 watchdogs, one implemented in hardware and another in software [3]. The board can also be bought at eBay here. In order to access the watchdog functions on the ESP, we have the EspClasswhich can be analysed in more detail here. We can access the functionality of this class by using an extern variable called ESP, which is declared here in the libraries.

Although this disables the software watchdog, the hardware watchdog will still remain active, causing a reset after some time.

As indicated in the comments of the wdtDisable method, if we stop the software watchdog by more that 6 seconds, the hardware watchdog will trigger. This is approximately what I got when testing it. We can re-enable the software watchdog by calling the wdtEnable method, as indicated bellow. In order to explicitly restart the watchdog, we can call the wdtFeed method, specified here.

To trigger the hardware watchdog, we just need to disable the software watchdog timer and do an infinite loop. We can do all of these actions in the setup function, as indicated bellow. Note that we will do an infinite loop with a while loop. After uploading the code, open the serial port to check the output. When the watchdog fires, a crash log is printed to the serial port, as indicated in the figure 1. Figure 1 — Crash log of the hardware watchdog reset.

As indicated in the figure, there is a mention to the cause wdt reset and the reset cause has the number 4, which corresponds to the hardware watchdog reset [4]. You can check other reset code here. This result is consistent with the indicated in this document. In order to trigger the software watchdog reset, we just use the same code as before and remove the disabling of the software watchdog enabled by default.

In this case, after uploading the code and opening the serial port, we will just get the result illustrated in figure 2, when the software watchdog triggers. Figure 2 — Crash log of the software watchdog reset.We reviewed dozens of LED lanterns to identify the best of the best. We looked at light strength, length of hours per charge, durability, and extra features such as USB charging. All of these products can be found online at Amazon. The amount of lighting modes, the extra D ring that allows for multiple ways to hang the lantern, and the battery life all make this LED lantern an excellent choice.

It runs on three D cell alkaline batteries not includedand is built with polycarbonate lenses and a rubber molded base that gives extra stability on uneven or slippery surfaces. The lantern has a handle for easy carrying or hanging, as well as a battery level indicator light that changes from green to yellow to red when the batteries are low. A nice extra feature are the D rings that are installed on both the top and bottom of the lantern, allowing you to hang it upright or upside down.

One of the most versatile functions of this lantern is the five different lighting modes. The white light modes include a high, medium, and low setting. The high mode has the brightest light at lumens and will run for 30 hours. The medium setting is lumens and will run for 70 hours, while the low setting is 55 lumens and will run hours.

The red LED light also has two settings, the high night mode is 10 lumens and will run hours, and the flashing SOS mode for signaling in an emergency is 10 lumens and will run hours.

This lantern comes with a removable polycarbonate cover that helps reduce glare when installed resulting in soft, even lighting. You can also remove the cover to allow the lantern to give off a much brighter light. The lantern can then be hung upside down by the D ring located on the underside to flood a larger area with brighter light.

Reviewers love the different light modes and say it gives off great light for camping as well as during power outages at home. The Vont LED Camping Lanterns collapse for easy storage yet still provide a large amount of light without needing to be plugged in.

Made from military grade materials, these lanterns can survive up to a ten foot drop and temporarily getting wet from the rain. The patented, collapsible design not only allows you to easily store the lanterns when not in use, but also lets you reduce the light as needed. No buttons are used to turn the lanterns on and off, simply unfold the handles and pull up to turn the lantern on, then push back together to turn off.

You can pull the lantern up halfway up for dimmer light, or pull all the way open for full light. Each lantern runs on three AA batteries which are included and will give light for over 30 hours. When the lantern is fully extended it measures 3.

They come as a set of four, so you can add a few to camping or emergency stashes to make sure you always have a way to see. Reviewers like that the light is incredibly bright for a small lantern. They also love the collapsible feature for easy portability and say these lanterns great for emergency or blackout situations as well as camping.

This lamp provides an output of lumens, and can run for up to six days straight on a new set of three D batteries. The AYL Starlight offers a high, low, and flashing strobe lighting mode. The lights can be easily switched between these three settings by pressing the switch button. A removable reflector cap gives degree lighting and can also be removed for a more focused beam.

The carrying handle can also be used to hang the lantern upright while the reflector is in place. The batteries are easily replaceable by simply twisting off the bottom cap and inserting new batteries. The portable, handheld size makes it easy to take hiking or camping, but the bright light output also makes this a great choice to have around the house for emergency situations. Reviewers like the long-lasting, powerful light and the fact that it only needs three batteries to run.
