C++ (Cpp) system_enable_interrupts Examples

Example #1

File: main.c Project: blanc15g/cs107e.github.io

void main(void) {
    keyboard_init();
    printf_init();
    timer_init();
    system_enable_interrupts();

    while (1) {
        int key = keyboard_read_scancode(); 
        printf("%02x ", key );
	if (key != 0xf0 && key != 0xe0) {
            printf("\n");
	}
    }
}

Example #2

File: lab7.c Project: bradleyemi/ir-sonar-baremetal

/*
 * Disable all interrupts except  GPIO interrupt 0, which is for pins 0-31. This
 * interrupt is IRQ 49, so bit 17 of the second register (BCM2835 ARM
 * Peripherals Manual, top of page 113).
 */
void kdriver_init() {
  gpio_init();

  // Ensure all interrupts are disabled.
  PUT32(RPI_INT_DISABLE_1, 0xFFFFFFFF);
  PUT32(RPI_INT_DISABLE_2, 0xFFFFFFFF);

  // We'll be hooking up a button to Pin 23, so set it up appropriately.

  // Enable GPIO interrupt 0
  PUT32(RPI_INT_ENABLE_2, 0x00100000);

  // Enable interrupts
