3/1/2024 0 Comments Google set timer 1 minuteSimply check if 'seconds' is 60 or whatever, if it is, then execute your code. The interrupt gets called every 1 second and adds 1 to 'seconds'. I tested its accuracy and it works consistently down to the microsecond. Here is a slightly modified program I made to easily set up timed interrupts. Attempting to install timers in Seconds for iOS. This code sets the prescaler to 1024, as slow as you can get.Ī prescaler of 1024 allows for a maximum time of 8388.608mS or ~8.3 seconds clockSelectBits = _BV(CS12) | _BV(CS10) Dont have Seconds Interval Timer yet Download on the App Store Download Seconds Interval Timer on Google Play. So, cycles is NOT less than RESOLUTION - 1, therefore it was more than maximum If(cycles < RESOLUTION) clockSelectBits = _BV(CS10) // no prescale, full xtalĮlse cycles = RESOLUTION - 1, clockSelectBits = _BV(CS12) | _BV(CS10) // request was out of bounds, set as maximum You can also pause the timer at any time using the 'Pause' button. You can reset the timer at any time using the 'Reset' button. The timer will alert you when it expires. Press the 'Start' button to start the timer. long cycles = (F_CPU / 2000000) * microseconds // the counter runs backwards after TOP, interrupt is at BOTTOM so divide microseconds by 2 A countdown timer for 1 minute and 10 seconds. Your code, which would have showed me the library you were usingĪnyway, here is what I found in the library I ASSUME you are using. I had to do alot of googling, which most people WILL NOT DO, simply because you failed to tell us basic things about your problem, such as: First of all, PLEASE read the How To Use This Forum thread before you post.
