Pipe_Break_ALS main.c file

C/C++
Replace the main.c text with this file. Use for Pipe_Break_ALS program. The file is located in the scr folder.

/*  This program will read the LUX value and compare it to a threshold value in "main.h" file.
    If the "button0" is pressed the system is considered armed.
    If armed and the LUV value exceeds "THRESHOLD_LEVEL_LUX: value in the "main.h" file,
    the spare output is set high for a period defined in "main.h" "DIO_OUTPUT_INTERVAL_MS".
    Note that the output "PIN_GIO_SPARE" is treated as a LED to turn it on/off
    The output "PIN_GIO_SPARE" is labeled "GIO" on the board located in the 5 hole pattern.

    Steps to use this program:
    1)  Copy "sense_ics_firmware" to the Project Explorer View from CMSIS Pack Manager View.
        It is called "Custom Service Firmware (RSL10-SENSE-GEVK)" in the CMSIS View.
        Using this project ensures that all of the required BDK components are included.
    2)  In the Project Explorer View, rename the project.
    3)  Rename "xxxxxxx.rteconfig" file to the new project name.
    4)  De-select the BLE - peripheral server - BASS component to remove battery status.
    5)  Replace the code in the "main.c" file with this code (copy / paste).
    6)  Replace the code in the "main.h" file with the new "main.h code"
    7)  Delete the file CNS_PB.h in the include folder.
    8)  Delete the file CNS_PB.c in the src folder.
    9)  Build the project, Debug and Flash the RSL10.
