![]() Send commands via the arduino serial console, D500 for 500µs delay, L100 for a 100µs long pulse. There are five types of triggering Arduino interrupts: Change: When signal change even if signal rise or signal fall or if the signal is in low state at 0 or if the signal is in high state trigger 5v. In I/O devices one of the bus control lines is dedicated for this purpose and is called the Interrupt Service. In Arduino interrupts, you can set how the interrupts are been triggered. It alerts the processor to a high-priority process requiring interruption of the current working process. I have also tried changing the timer prescaler, but then the jitter is also scaled up in an unacceptable way. The interrupt is a signal emitted by hardware or software when a process or an event needs immediate attention. So, if any part of your code uses a delay (), everything else is dead in the water for the duration. The delay () ties up 100 of the processor. During a delay () call, you can’t respond to inputs, you cant process any data and you can’t change any outputs. How would I go about extending that range into the millisecond range (say up to 1s or so)? Since this example is interrupt-based, adding delay() statements do not really seem to work. The problem is that delay () is a 'busy wait' that monopolizes the processor. ![]() Delay is not good to be used in this circumstance. You can do this but not as you have implemented. I already found an excellent example in Generating a short pulse after a delay that works in the range from ~5-32767 microseconds (it is limited by a 16 bit microsecond counter divided by 2). 1 Answer Sorted by: 1 Wow that was rude ignacio At least be helpful.
