LED blink using while loop example

Schematic

Pocket Beagle

BeagleBone Black / Beagle Bone Black Wireless

Code

while : true {
    digital_write(P1_31, true);
    delay(1000);
    digital_write(P1_31, false);
    delay(1000);
}

• Following code works on PocketBeagle, to use on other boards, please change the pins accordingly.

Explaination

This code runs a never ending while loop, since it is while : true. Inside while it sets header pin P1_31 to HIGH, waits for 1000ms, then sets header pin P1_31 to LOW, then again it waits for 1000ms. This loop runs endlessly, so we get a Blinking output if one connects a LED
