Hi erik, Although the timer itself has a precision of 0.5 microseconds, the overall precision will be less than that because of the overhead of the interrupt handling. So in reality I don't think you would get any greater accuracy if the pulse width was given to half a microsecond. Ideal for your Christmas lighting. Brand New (Never Used, still in the original box) Outdoor timer tdc model no. da-88-12w-1 $20. Multiple settings to allow your landscape lighting to come on at dusk and remain on for a select number of hours, up-to 8 hours, or dusk-to-dawn. Circuit Breaker Protection Manual On/Off setting Hourly Settings for 'ON' time operation The Power Pack Timer has the. Looks vaguely plausible - but you don't need to do anything to the prescaler, it isn't used when the timer clock source is the external pin. You are enabling a lot of interrupts, why? What exactly do you want to achieve and how is your code behaving? Hi, Since I wanted to play with the MsTimer2 library (Arduino Playground - MsTimer2), I've downloaded the zip file and decompressed it into arduino/libraries, next to the rest of libraries. Finally, I've checked that the source files were contained into its own subfolder: arduino/libraries/MsTimer2/ Now the compiler complains about the following line in my code: include MsTimer2.h saying. Hi Leute! Ich habe einen Arduino Mega 2560. Ich habe gehört, dass ich auf dem AVR Interrupts Timer-gesteuert auslösen kann, z.B. alle 30ms. Das muss wohl über Zähler gehen. Kann ich alle Timer nutzen, ohne mit den Standard-Funktionen (keine extra Libs) in Konflikt zu kommen? Ich könnte mir vorstellen, dass Serial und PWM auch Timer nutzen könnten. Hi I want my form timer event to run every five minutes on the minute. I achieved this is Visual Studio using Me.Timer1.Interval = New TimeSpan (Now.Hour, Now.Minute + 1, 0).Subtract (Now.TimeOfDay).TotalMill iseconds How would I do the equivalent in Access VBA Me.TimerInterval = ??????? I need to setup a route pattern so that when someone dials 9 + 1 + number i.e. 9 1 111 222 3333 the system manipulates it and sends it out the PSTN as follows 001 111 222 3333. Also add after the last digit to terminate the t302 timer what should my route pattern look like? I also want CDR to log the call as 91 111 222 3333 or 1 111 222 3333 or 111 222 3333 CUCM version is 8.0.2 Thanks. Find answers to vb.net system.threading.timer from the expert community at Experts Exchange When I look at examples of interrupt code, I keep seeing what appear to be defined/reserved labels for the compiler to recognize ISR (interrupt service routine) vectors, eg, ISR(TIMER1_COMPA_vect) Is there a page where all these vectors are defined/listed? Is there a way in the Arduino IDE or C++ that allows the programmer to explicitly establish the interrupt vector and write the ISR at a low. It's a learning excersize so I can figure out how to move from using the delay to using a timer. I've spent ages trying to figure this out so I'd really appreciate any help.
