WebIRQ_FALLING, handler = callback) We set pin 0 to trigger only on a falling edge of the input (when it goes from high to low), and set pin 2 to trigger on both a rising and falling edge. After entering this code you can apply high and low voltages to pins 0 and 2 to see the interrupt being executed. WebIRQ_TYPE_EDGE_BOTH is not supported. It application requires interrupt on both rising and falling edges, software can set the IRQ type to level trigger and set the polarity in reverse to the current GPIO input level. Below is the example. value = …

WebThe approach here is to use PDC interrupt at all times (while keeping the GPIO irq disabled). The PDC interrupt handler invokes the action handler of the GPIO IRQ instead. This allows us to avoid interrupt hand-offs while entering idle states and keeps things very simple. The wake_irq_gpio_handler() is the crux of this new revision.
