The result is not very far from the interrupt latency seen by. Therefore, the measured interrupt latency 82 / 16M 5s. This means the Timer1 counter register has a value of 82 ticks at the beginning of the ISR handler function execution. UPDATE: OK, after some experimenting, I think that incorporating the delay() function in the ISR is a big error since the delay function also depends on the. Is there any way to pause without using delay()? I have heard of using Millis() but I am new to Arduino's and im not sure how I would implement it at all. First Arduino project : Leds stripes with 2 loops running at a time. Here is the result of running this interrupt latency measurement code example on my Arduino UNO board. The issue is that the button must be held down right when the loop restarts and if you click it any other time it wont work, I think this is because I am using delay() which pauses everything. My goal is that when the button is pushed on the pi it sends a signal to the arduino Uno which will change the animation on the LED backpack. In I/O devices one of the bus control lines is dedicated for this purpose and is called the Interrupt Service. ![]() It alerts the processor to a high-priority process requiring interruption of the current working process. I am using an arduino uno, logic level converter, adafruit Bicolor LED Matrix, a Raspberry pi, and a button but am having some issues. The interrupt is a signal emitted by hardware or software when a process or an event needs immediate attention.
