This program was an introduction to attaching interrupts on a gpio pin The video shows this simple example, with a rapid, on screen, count running on core 0 and blinking/ moving leds on core 1 An interrupt can be generated for every gpio pin in four scenarios
Timers and Interrupts on Raspberry Pi Pico W
The gpio is logical 1, the gpio is logical 0, there is a falling edge.
These rpi_pico_timerinterrupt hardware timers, using interrupt, still.
The majority of examples are applicable to both rp2040 and rp2350 based. In this tutorial, we will learn how to use an rir motion sensor with raspberry pi pico and configure external interrupts of raspberry pi pico using micropython. This document describes the hardware irq handling system provided by the hardware_irq library in the pico sdk It covers interrupt handler installation, priority configuration, shared handler.
