Could Not Disable Interrupts On Connected

An interrupt can occur at the very same clock cycle that the bcf GIE instruction is fetched, then the interrupt is recognized, the instruction is executed, the interrupt is serviced, and Why I cant' even blink a led with pic18f4680? I need to turn off all interrupts so that I can guarantee a timed sequence of events. Advertisement Recent Posts Crashing intermittently for... check over here

It is possible to schedule such timeslots regularly at any interval, but there may be cases where the timeslot scheduled can be denied due to critical events in a connection, for Show Ignored Content As Seen On Welcome to Tech Support Guy! You'll be able to ask any tech support questions, or chat with the community and help others. When I implemented the shadow interlock, the interrupt 'leakage' was fixed. see it here

If it's not clear after reading it, then you're probably not in a position to try writing the code. I wrote this post a week or so outlining how someone could try to use the Multiprotocol Timeslot API which gives you occasional, irregular, small slots of time during which you I could make my system to fail by removing the GIE interlocking mechanism. But when exiting the while() loop, interrupts will be disabled, and the critical section can be run with no problems. >> ADDED: I was not understanding your point.

So, the test for (INTCONbits.GIE==1) can be interrupted several times, and it will still be processed as if nothing happened. Check out the Tour!

So before theexecution reaches that critical part, you have a copy of the GIE flag, which you can use at the end of the critical part where you must restore the

However, if you do not want to generate errors in the event log, disable the MSi8042 device driver and enable the i8042 Keyboard and PS/2 Mouse driver.Reference LinksEvent 10 After Installing You say that IF the ISR disables GIE, then the GIESet mechanism will be broken. If yes then how to do that?2) What is the maximum timeslot (in ms) we can ask for? 3) What is the probability that we ask for a timeslot and we Edit: If however the softdevice is disabled, or it's ok for your application to risk getting asserts back from the softdevice, you can use the CMSIS functions __disable_irq() and __enable_irq() to

As we have known in 8051, the instruction is simply 'EA=0'. In either case, you are burning a char so it's going to come down to the smaller ASM code. My mouse works FINE but I still have the error message. 4. To [j_doin] I am using 18F8680.

I regard this as a architecture characteristic, not as a silicon bug.

Could not enable interrupts on connected port devic \Device\PointerClass1. The message shows up during or just after the Windows logon. Is there some amount of time that I can turn off interrupts for less than and not interfere with the SD? Please add your comments and questions (which we try to answer), as this increases the event repository usefulness for all of us.

The max period you can disable interrupts is ZERO, you may not disable interrupts when the softdevice is running, not for 1ms, not for 1us, not at all, not ever. edit flag offensive delete publish link more No, I don't think that's a correct assumption, since you should be able to use the critical regions to protect such code. With that feature, you can request timeslots where the SoftDevice's links is guaranteed to be idle, and you can for instance disable interrupts safely. The interrupt will resume operation before the GIE while() loop.

You can't really save INTCON, because interrupt can come in after you save INTCON but before you disable INTCON.GIE and this interrupt happens to change some of the other bits in edit flag offensive delete publish link more I've edited and extended my answer above somewhat, but beware that this is a very scary thing to do that can have bad consequences.Ole Any info will help, thanks!
