Next add the highlighted code below in the main function and the code inside the while loop, resulting in the
code shown below:
void
main(
void
)
{
/* Initialize the switch module */
R_SWITCH_Init();
/* Set the call back function when SW1 or SW2 is pressed */
R_SWITCH_SetPressCallback(cb_switch_press);
/* Initialize the debug LCD */
R_LCD_Init ();
/* Displays the application name on the debug LCD */
R_LCD_Display(0, (uint8_t
*
)
" RSSKRX23W "
);
R_LCD_Display(1, (uint8_t
*
)
" Tutorial "
);
R_LCD_Display(2, (uint8_t
*
)
" Press Any Switch "
);
/* Start the A/D converter */
R_Config_S12AD0_Start();
while
(1U)
{
uint16_t adc_result;
/* Wait for user requested A/D conversion flag to be set (SW1 or SW2) */
if
(TRUE
==
g_adc_trigger)
{
/* Call the function to perform an A/D conversion */
adc_result
=
get_adc();
/* Display the result on the LCD */
lcd_display_adc(adc_result);
/* Reset the flag */
g_adc_trigger
=
FALSE;
}
else
{
/* do nothing */
}
}
}
Then add the definition for the switch call-back, get_adc and lcd_display_adc functions below the main
function, as shown below:
/******************************************************************************
* Function Name : cb_switch_press
* Description : Switch press callback function. Sets g_adc_trigger flag.
* Argument : none
* Return value : none
******************************************************************************/
static
void
cb_switch_press (
void
)
{
/* Check if switch 1 or 2 was pressed */
if
(g_switch_flag
&
(SWITCHPRESS_1
|
SWITCHPRESS_2))
{
/* set the flag indicating a user requested A/D conversion is required */
g_adc_trigger
=
TRUE;
/* Clear flag */
g_switch_flag
=
0x0;
}
}
/******************************************************************************
* End of function cb_switch_press
