Hi all, I'm newbee so please be patient reading my post :-). I have code as below (Which is working properly on FRD-KE04Z) but this development board is using external oscillatror. I have my own simple board based on KE04Z but I need to use internal oscillator. Please help me how to set it up KE04Z to use internal oscillator.


int main (void)
RTC_ConfigType sRTCConfig;
RTC_ConfigType *pRTCConfig = &sRTCConfig;
/* Perform processor initialization */

printf("\nLED exaple.\n");

/* configure RTC to 1Hz interrupt frequency */
pRTCConfig->u16ModuloValue = 9;
pRTCConfig->bInterruptEn = RTC_INTERRUPT_ENABLE; /* enable interrupt */
pRTCConfig->bClockSource = RTC_CLKSRC_1KHZ; /*clock source is 1khz*/
pRTCConfig->bClockPresaler = RTC_CLK_PRESCALER_100; /*prescaler is 100*/


GPIO_PinInit(GPIO_PTE7, GPIO_PinOutput);

while (1);





void RTC_Task(void)
printf("\nLED state changed.\n");
