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. WebJan 22, 2024 · When you want a high-level interrupt, you cannot use this function, as the GPIO driver function is written in C and high-level interrupts need to be in assembler. So gpio_install_isr_service should not be called. Furthermore, you call intr_matrix_set, but with the pin number as the second argument. From memory, this should be the interrupt number.
