Arduino leonardo interrupt pins. Long story short, I ended up copying the macros for interrupt bitmasks/registers from the Teensyduino project, which has a mega32u4 target board. Feb 22, 2013 · Hello, I am having a weird problem with the Leonardo mini board and using INT 2 and INT 3. Yet, it does not do this on the Duemilanove. These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value. It has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. But when the interrupt fires on INT 2 it also calls the interrupt handler attached to INT 3, even when I completely detach the input sensor from the assigned pin for INT 3. The problem is I attach an interrupt handler to INT 2 and to INT 3. Can you help me out? 4 days ago · Arduino Uno vs Nano vs Mega — detailed specs comparison, pin differences, use cases, and price guide to help you pick the right board for your project. External Interrupts: 3 (interrupt 0), 2 (interrupt 1), 0 (interrupt 2), 1 (interrupt 3) and 7 (interrupt 4). Jan 31, 2016 · Pin 7 is an external interrupt pin on the Leonardo, no need for pinchange interrupts. wzwdtluxlcddkguzwbskpmxpdsckalogdkzasbypqxfqxidpzez
