Hello ,

I am currently working on ARDUINO uno with RTC and the RTC data display on TFT.

I have done everything regarding to RTC using the RTClib.h and wire.h in 12 hour format but still not set the Am pm format on it.

I started the RTC in 12 hour mode like these,

DD = now.day();
MM = now.month();
YY = now.year();
H = now.hour()%12; ///the 12 hour format
M = now.minute();
S = now.second();

It work fine but, how can i call the Am & Pm in accordance with time update?

where I will change to get the Am PM pattern and how I call it for TFT print?

By changing the sketch accordingly. We cannot help because you're keeping the sketch, the wiring and all information about the hardware secret.

If that snippet above is your actual code, you get the flag

bool pm = now.hour() / 12;

sorry pylon for late reply ,

but I managed to get the same structure from 24 hours,like these

if (now.hour() > 12 )
{
H = now.hour() - 12;

}
else
{
H = now.hour();
}

if (now.hour()>= 12 )
{
tft.setCursor(440, 300);
tft.println("Pm");
}
else
{
tft.setCursor(440, 300);
tft.println("Am");
}

so thanks for your teply..
