Interrupt on pin 0 and 1 (INT2/INT3) on Pro Micro - Arduino Forum
2017年11月25日 · Hi, I am doing a project to monitor and control my PC fans using a Pro Micro board. As I understand pin 0, 1, 2, 3 and 7 can be used with interrupts using attachInterrupt. I can get pin 7 to work but when i try to use pin 1 or 0 I get incorrect rpm values if the fan is …

2012年2月7日 · If you attach an interrupt to an interrupt-enabled pin, you'll need to know the specific interrupt that pin triggers: pin 3 maps to interrupt 0 (INT0), pin 2 is interrupt 1 (INT1), pin 0 is interrupt 2 (INT2), pin 1 is interrupt 3 (INT3), and pin 7 is interrupt 4 (INT6).
Pro Micro Interrupt problems - Microcontrollers - Arduino Forum
2014年2月20日 · The Pro Micro has five external interrupts, which allow you to instantly trigger a function when a pin goes either high or low (or both). If you attach an interrupt to an interrupt-enabled pin, you’ll need to know the specific interrupt that pin triggers: pin 3 maps to interrupt 0, pin 2 is interrupt 1, pin 0 is interrupt 2, pin 1 is ...
attachInterrupt () - Arduino Reference
2024年11月8日 · Digital Pins With Interrupts. The first parameter to attachInterrupt() is an interrupt number. Normally you should use digitalPinToInterrupt(pin) to translate the actual digital pin to the specific interrupt number. For example, if you connect to pin 3, use digitalPinToInterrupt(3) as the first parameter to attachInterrupt().
Pro Micro INT Pin confusion - Arduino - SparkFun Community
2021年3月2日 · The other Pro Micro pins can also be used, as each block of 8 pins is associated with a pin change interrupt. This interrupt can be configured to trigger when a given pin changes. The difference is that the interrupt handler “PCINT{n}” is responsible for determining which pin triggered it and what the pin state (high or low) is.

These registers support interrupts on Pro Micro pins 8, 9, 10 or 11. This example wires the encoder to pins 8 and 9. Note that the interrupt vector also changes to correspond to the PCIE0 interrupt.
Pro Micro interrupts 0 & 1 work, 2 - 4 do not - Arduino Forum
2013年6月4日 · According to the AttachInterrupts page (http://arduino.cc/en/Reference/attachInterrupt) the Leonardo and ProMicro should support interrupts on pins 0, 1, and 7 as well. Am I missing something? My program is as follows, I just changed the interrupt number to test: attachInterrupt(4, test, CHANGE); if (flag == …

2019年6月28日 · I am using a Pro Micro which has interrupt pins at pin0 and pin1. The code below works as expected. My question: do I need to use an interrupt pin for PinB as well, or can I use any digital pin?
Arduino Micro Pinout, Specifications, Schematic & datasheet
2024年3月26日 · There are 4 external interrupts pins on the Arduino Micro board: 3 (INT 0), 2 (INT 2), 0 (INT 3) and, 1 (INT 4). The interrupt pins can be configured to trigger the interrupt if any of the following changes occur: a low value, a rising or falling edge, or a change in value. SPI Pins . It stands for Serial Peripheral Interface.
