* Description        : This example shows how to use the software library to
*                      manage the converter in the single channel mode
*                      of conversion.the converter in this example is managed
*                      in the interrupt mode.
*                      Getting the conversion result is done in the interrupt
*                      handler of 71x_it.c file.
