This article shows how to use one of the pins on the SJ-One board as either an INPUT or OUTPUT pin.

== Steps ==
Check to see if you have '''gpio.hpp''' in your project's '''L4_IO''' directory, if not, follow these steps :
* Grab the GPIO header file from SourceForge [https://sourceforge.net/projects/cmpe146freertos/files/ SourceForge SJ-One Project]
*: You will get the '''gpio.hpp''' file
* Put this in your Project's '''L4_IO''' directory

<BR/>
To use a pin for GPIO, see the source code example below :
<BR/>

<syntaxhighlight lang="c">
/// Include the GPIO file
#include "gpio.hpp"

int main(void)
{
/**
* Locate a pin on your board that you'd
* like to use either as INPUT or OUTPUT
* Let's use P1.19 (as labeled on the Board)
*
* You can use any other pins as defined by
* LPC1758_GPIO enumeration at gpio.hpp file.
*/
GPIO myPin(P1_19); // Control P1.19
myPin.setAsOutput(); // Use the pin as output pin

// Let's blink an LED on P1.19 :
while(1) {
myPin.setHigh(); // Pin will now be at 3.3v
delay_ms(100);

myPin.setLow(); // Pin will now be at 0.0v
delay_ms(100);
}

return 0;
}
