Greetings from Mexico
Can you help please with ASM or C code to use the Time Keeper Maxim DS3232 with PIC16F and PIC18F micros.
It is noteworthy that the DS3232 is better, much more accurate, does not require of 32.768 kHz XTAL because it has integrated into the package and is replacing the ds1307. The trouble is that no code on the (...)

increment an int in RB0 interrupt service routine. (say count++;)
Then in main program introduce a code to convert the count to corresponding decimal digits and send the ascii of the digits to LCD one by one , from the MSB to LSB. Before that set the LCD cursor position. (say 0x80)
Now i think you can do it...You mean you want the exact code?

I would ignore what is in the registers by default and init them to some arbitrary value that results in somtlhing like jan 1 2000. If your clock keeps time when the device is off (via battery) you can store a known byte to an EPROM location when you run the "first time int" code. That keeps you from clobbering a real time value.
