WebJan 11, 2024 · pigpio uses interrupts, e.g. with the gpioSetISRFunc function. lgpio uses interrupts. e.g. with the gGpioSetAlertsFunc function. None of the above use polling or busy waits. I can only assume you are confused because at a low level they use a Linux function called poll. But this function does not poll the GPIO in the sense you mean. WebApr 18, 2024 · Hi Alexander, You are close. By default GPIOs are controlled by the CPU and the CLA doesn't have access the registers. As of today, our GPIO block only works from the CPU. We are working on enhancing this for the future. In the meantime, just use a simple line of custom code to change the master that has access to the GPIO registers.
