}
}
Then, add the following function definition at the end of the file:
/******************************************************************************
* Function Name : led_display_count
* Description : Converts count to binary and displays on 4 LEDS0-3
* Argument : uint8_t count
* Return value : none
******************************************************************************/
static void led_display_count ( const uint8_t count)
{
/* Set LEDs according to lower nibble of count parameter */
LED0 = (uint8_t)((count & 0x01) ? LED_ON : LED_OFF);
LED1 = (uint8_t)((count & 0x02) ? LED_ON : LED_OFF);
LED2 = (uint8_t)((count & 0x04) ? LED_ON : LED_OFF);
LED3 = (uint8_t)((count & 0x08) ? LED_ON : LED_OFF);
}
/******************************************************************************

studio will build the project with no
errors.
The project may now be run using the debugger as described in §6. The code will perform the same but now
the LEDs will display the gs_adc_count in binary form.
