WebOct 22, 2016 · The GPIO mux basically allows you to pick a random interrupt for a peripheral; any that are marked as free in the table you mentioned will work. That's why he is saying don't use it here: Code: Select all. gpio_isr_register (INPUT_GPIO, gpioCallback, ( void *)TAG); // 17. By coincidence, INPUT_GPIO = 17 so it works. WebOct 1, 2024 · For example, if P0_3 changes its value, its flag will be set inside the GPIO peripheral but the CPU only executes the ISR in response to the PORT0 interrupt flag from the interrupt controller. Checking the GPIO peripheral interrupt flags inside the ISR tells us which specific pin produced the interrupt so we can respond accordingly.

WebInstall the driver’s GPIO ISR handler service, which allows per-pin GPIO interrupt handlers. This function is incompatible with gpio_isr_register() - if that function is used, a single global ISR is registered for all GPIO interrupts. If this function is used, the ISR service provides a global GPIO ISR and individual pin handlers are ... WebCall this function after using gpio_install_isr_service() to install the driver’s GPIO ISR handler service. This ISR handler will be called from an ISR. So there is a stack size limit (configurable as “ISR stack size” in menuconfig). This limit is smaller compared to a global GPIO interrupt handler due to the additional level of indirection. kneading neck massagerWebSep 24, 2024 · It seems like have some GPIO ISR init happening in camera_init routine.
