I believe that the ONLY way to mask interrupts while single-stepping is to clear the IE flag bit in the Status Register. Jim Wagner On Feb 6, 2013, at 6:54 PM, Dave McLaughlin wrote: > Thanks John and all, > > It's not just the timer interrupt, I also have CAN bus interrupts runn

Thanks John and all, It's not just the timer interrupt, I also have CAN bus interrupts running. The timers halted option is set anyway. I don't recall ever having to disable interrupts before. Doing a search I come across a few references to an option to mask interrupts during si

Go to the view of the peripheral registers and clear the interrupt enable bits of the timers or other devices that are making things hard. Or, go to the Status Register and clear the global interrupt enable bit. Jim Wagner Oregon Research Electronics ----- Original Message -----

It looks like you are expecting the address of the struct passed to your function but not using the address in the function. Try it this way: void CalculateOffTime(uint8_t duration, offTimeStruct eventOff) { ... } Also, I think the typedef is wrong. Try it this way: typedef struc

In my work experience we service the WDM within the schedule. The OS that we wrote is for flight control so deterministic. This allows us to service WDM reliably. The WDM that we use is within a PLD that we design. Not that you ever need a WDM. : ) --- In AVR-Chat@yahoogroups.com

I can't answer about the early strobe, never having seen that either, but on some medical stuff that I've worked on the FDA did not allow the WDT to be part of the micro. They demanded an external WDT wired to the reset line. Of course, mine never triggered either. ----- Original

Just to satisfy my curiosity, what chip has a watchdog timer with an "early strobe" exception? I've never encountered that in my (possibly flawed) recollection of my past 35 years of doing this stuff. It would be pretty annoying to have to keep track of the more-or-less time sinc

2013-01-25 by Philippe Habib
You can also set the BOD to different voltages. Are you able to run the part at a high enough voltage to allow enough time to run some cleanup stuff in the interrupt before the voltage goes all the way down? Maybe just increasing the size of some of your capacitors would give you

2013-01-24 by Chuck Hackett
How does one detect that VCC is dropping so that one can do cleanup activities (reset external controllers that would leave devices in an unknown state, etc.) before a BOD reset occurs? From my reading of the ATMega1284 datasheet I don't see any detection other than the BOD reset

Nothing about "non-periodic". Here is how it works: 1. WDT timer is reset 2. WDT timer counts If the WDt timer is reset before the count overflows, go back to 2. If the timer overflows, it resets. So the ONLY criterion is that the timer is reset before it overflows from the previ
2013-01-12 by Jim Wagner
You can reset the WDT at ANY interval less than the timeout time. You could have it set for 60ms and reset it once every 1ms. No difference. Jim Wagner On Jan 12, 2013, at 9:12 AM, englsprogeny1 wrote: > To test this I go into an infinite loop (by way of a UART command). > > My W
2013-01-12 by Jim Wagner
This is exactly the same. The code has to periodically reset the WDT when it is running. If your code DOES NOT reset it, the WDT will eventually time out. You do not have to reset it to start it. You can enable/disable the WDT and you can set the time in large increments. Enable/

It can be argued, quite strongly, actually, that an endless loop is the ONLY error that the WDT handles. Nothing else "triggers" the WDT. Jim Wagner Oregon Research Electronics On Jan 12, 2013, at 7:35 AM, englsprogeny1 wrote: > Using an AtMega16, I am going to make use of the wa
2013-01-12 by Jim Wagner
The only "crash" of any significance is the endless loop. You look for an I2C peripheral thats not there? That is just an error and the code flows on. Same with virtually everything else. So why not a simple endless loop? You COULD call a function and purposefully corrupt the sta
2013-01-12 by englsprogeny1
OK That makes sense. So really, there is an 'early strobe' exception by way of the WDT expecting a periodic reset. The WDT must then measure the time between resets. So the WDT causes a reset for two conditions: 1. Not being reset before his timeout 2. Having a non-periodic time
2013-01-12 by englsprogeny1
To test this I go into an infinite loop (by way of a UART command). My WDT is set for 60ms. I am resetting the WDT at 35ms. This means that I am resetting the WTD early (really early). It works correctly. So, there appears to be no issue with early resets. (as in really early)...
2013-01-12 by englsprogeny1
Thanks Jim. Using an endless loop is sufficient for verifying my WDT implementation. A follow on question. I just read the ATMega16 datasheet to see that the WDT has to be serviced before it times out. OK, of course... On other WD Timers that I've worked with, there was also an '

Using an AtMega16, I am going to make use of the watchdog Timer. I want to cause a crash to verify that the WDT brings us back to life. Instead of going into an infinite loop "crash" I'd like to cause something more catastrophic. I tried a divide by zero scenario but we don't cra
