* This document provides an example to control the fitlet2's front LEDs.* fitlet2 has 2 LEDs, LED1 and LED2. Each of them has GREEN and YELLOW parts that can be controlled separately.* This document is applicable to fitlet2 running Linux or Windows.
== Windows ==
* Download the driver from - [http://fit-pc.com/download/fitlet2/sw/drivers/win10/fitlet2_Win10_LED.zip Link]
The package contains:
* Driver\fitlet2.LED.Driver.exe - Driver installer.
* Sample Applications\SetLed\ - Sample application demonstrates the LED control (VS project)
There are 2 options for LED control:
1. Use the pre-made applications for LED control:
Led1Green.exe: Turn on the LED1 green
Led1Yellow.exe: Turn on the LED1 yellow
Led1Off.exe: Turn off the LED1
Led2Green.exe: Turn on the LED2 green
Led2Green.exe: Turn on the LED2 yellow
Led1Yellow.exe: Turn off the LED2
After the driver installation, all these applications can be found in the '''C:\Program Files (x86)\LED\ folder'''.
2. Develop an application using the DLL and LIB files.
After the driver installation, the '''LED.dll''', '''LED.lib''' and '''LED.h''' files be found in the '''C:\Program Files (x86)\LED\ folder'''.
== Linux ==
