How shall we flip GPIO 11, the Blue LED on PineCone #BL602? We edit the #NuttX GPIO Pin Definition ... And GPIO 11 becomes "/dev/gpout1"

GPIO Demo calls "ioctl" to control the GPIO Pins on #BL602 #NuttX

https://github.com/apache/incubator-nuttx-apps/blob/master/examples/gpio/gpio_main.c

"help" shows the commands available on #BL602 #NuttX ... "ls /dev" reveals the GPIO Pins that we may control ... Yep everything looks like a file!

After the GPIO Driver has been enabled, select the GPIO Demo in #BL602 #NuttX

Though SPI with DMA is not yet supported on #BL602 #NuttX OS

Timer Demo on #BL602 #NuttX opens "/dev/timer0" ... And controls it with "ioctl" and "sigaction" ... Looks like Linux
