BasysMX3 incorporates a wide range of modules. Digilent provides a set of libraries, allowing user easy access to each module’s functionality.

Basically, these libraries hide the hardware implementation details; they are wrappers over the lower level functions that access the registers, allowing the user to call the needed functionality in an easy and intuitive manner.

These libraries are designed to work in the MPLAB X IDE provided by Microchip.

Normally each library has a .c and .h file. In order to use this library:

• include in your project the .c and .h files corresponding to the module you want to use (for example led.c and led.h). This can be easily done by copying the files in the project folder and then Add Existing Item (right mmouseclick on the project source folders and project header files folders.
• In your code, include the header of the module

#include "led.h"

• In your code, call the needed functions, for example:

LED_Init();  
LED_SetValue(4, 1); //turn on LED4

Using these libraries is not required in order to access the Basys MX3 devices, of course you can write your own functionality (possibly using the libraries as inspiration).

The usage of each library is documented in the library's .c and .h file. An overview of all the libraries is found in the Basys_MX3_LibPack_UG.docx Word document.

Demos that use each of the libraries are found in the Demos folder. They are provided as MPLAB X projects.
