Description

Reverses the output of a pin. If it was low it will go high. if it was high it will go low.

  The pin number to toggle. The pin should be valid and configured for output.

Setup GPIO pin 16 for output, set to high (1) and then toggle:

uint32_t feature_set;
feature_set = librpipInit(LIBRPIP_BOARD_DETECT, LIBRPIP_FLAG_DEBUG_ON, 0);
if(feature_set & LIBRPIP_FEATURE_GPIO) { 
        librpipGpioConfigPinWrite(16, LIBRPIP_GPIO_FLAG_FNC_OUT);
        librpipGpioPinWrite(16, 1);
        librpipGpioPinToggle(16);
}
librpipClose();
