Using the PLL How can I get 12 MHZ FOSC, 6 MHZ FCY. My end goal is to configure the UART port to transmit at 1.5 Mbaud. thanks I am using a PIC24HJ32GP202 for my project, and I have a 6 MHZ external crystal connected to it.

Unfortunately I don't use the RTCC very often. There are several issues with the RTCC that I don't like about on the PIC24. I usually use an external chip. The price is a bit cheaper using the PIC24 directly with an oscillator, but you get more features (usually) with an external chip. You are on your own for this one. -J @qmash.

Your tutorials are realy good. I am new in pic, I would like to know that, how can initialize RTCC. I always get same time from RTC.I want to get time and date using PIC24FJ256GA018. I am using following initialization. OSCCON = 0x4402;//0010,0010,0000,0010 RCFGCALbits.RTCWREN = 1; RCFGCALbits.RTCEN = 1; RCFGCALbits.RTCOE = 1; PADCFG1bits.RTSECSEL=1; void TestRTC() { int sec; RCFGCALbits.RTCPTR = 0;//0-3 if( sec!=RTCVAL) { sec=RTCVAL; BlinkLED(); } } there is external oscillator 32768Hz connected at RC14,RC15 i always recv same bits pattern. thanks in advance for your assistance. HI.

I am new in pic, I would like to know that, how can initialize RTCC. I always get same time from RTC.I want to get time and date using PIC24FJ256GA018.
I am using following initialization.

OSCCON = 0×4402;//0010,0010,0000,0010
RCFGCALbits.RTCWREN = 1;
RCFGCALbits.RTCEN = 1;
RCFGCALbits.RTCOE = 1;

PADCFG1bits.RTSECSEL=1;

void TestRTC()
{
int sec;
RCFGCALbits.RTCPTR = 0;//0-3
if( sec!=RTCVAL)
{
sec=RTCVAL;
BlinkLED();
}
}

there is external oscillator 32768Hz connected at RC14,RC15
i always recv same bits pattern.
thanks in advance for your assistance.

I usually use external RTC chips for my application, and have not looked too much into it. Perhaps in the future. -J Hi AP, no, I have not done a section on RTCs.
