Here I would like to ask some help.....
For me it is the first time for interfacing HD44780 LCD with PIC 16F877....
How can I study for that......

So what is the different for programming with 16F877 and 16F84A?
How can I upgrade the souce code of 16F84A to 16F877?

Best regard
Thank a lot

How can I upgrade the souce code of 16F84A to 16F877?

If you use assembly language, there is almost no problem. Both PIC16F84A and PIC16F877 have exactly the same set of intruction. More, 16F877 includes all the registers that 16F84A has. I think the only care you should take is with the configuration bits and RAM registers used by your firmware.
