RTC + Military Time, Project Help

[Shake_ECET209]

Hi Guys, I am making a RTC that displays military time at the push of a button. I am using the code from the RTC lab we did and adding the LCD screen, but the code uses the RS232, and instead i want to use the push buttons on the board to set the time/hr/min and then display that time in military time.

Can anyone help me remove the use of the RS232 in the code we have not gone over it yet and I am really not similar with it.

Also Do I only need to change the <16F88.h> header file in order to make it work for the 16f88??

Thanks guys any help is appreciated

You should ask this question over on the MicroControllers forum.

Redirecting code from one processor to another requires changing the header file, as you said, but you also have to check that the new processor has the hardware support for everything that your program uses. For example, if the old processor has an A/D, but the new one does not, .... Or the old one has a PWM module, and the new one does not, etc....
