Now that we know the pin is configured as an output, it’s time to get blinking. We could use the GPIO_DATAOUT register to do this, but we would want to preserve the state of all the other bits in it, so we would need to do the same process of unpacking .....

NB. P6 is not available on BeagleBone Black IMPORTANT This diagram of P6 provides an UNDERSIDE PINOUT view. It is therefore laterally inverted relative to the photograph. To obtain the top-side pinout that corresponds to the physical orientation shown in ...
