Now that SysConfig selections have been made, SysConfig has auto-generated files containing library functions that can be called inside the user's application code to setup the tool, capture/buffer variable data, and transmit the data to the GUI to be plotted. Below are the steps for implementing these functions in an application.

1. Verify that the standard SysConfig "board.h" header file is included at the top of main C file and a call to Board_init() is present at the end of the initialization routine.

   #include "board.h"

   Board_init();

2. Additionally, include the signalsight/signalsight.h header file

   #include <signalsight/signalsight.h>

3. After the call to Board_init(), add another function call to SIGNALSIGHT_init() in the application initialization code. Have this be the last code executed before interrupts are enabled globally.

   SIGNALSIGHT_init();

4. Choose where in the program to read the current values of the plot variables and write these values to the buffer. Usually, this is done periodically in a PWM or CPU timer ISR. Add a function call to SIGNALSIGHT_capturePlotData() in this area of the application.

   SIGNALSIGHT_capturePlotData();

5. Choose where in the program to transmit the data in the buffer. Usually this is done in a low priority or background loop since the program can be blocked waiting for the SCI module to transmit the data. Add a function call to SIGNALSIGHT_sendPlotData() in this area of the application.
