Hi, I will use a 4-bit LCD with 8051. But there is a problem, LCD's data pins are connected in reverse order. i.e. D7 to P2^0 D6 to P2^1 D5 to P2^2 D4 to P2^3 My previosly written program uses a port called Data which is defined as #define Data P2 Now i want to simple change the "Data" definition with reversed ordered P2 pins, without changing the program itself. How can i do this?
I am not an expert. Just for a few months, i am dealing with keil c51. I am looking for examples, articles etc. I write this program myself. But i have searched a lot of thing and i study some codes doing this job. Then i combine these and write my own code. The danger of using "examples" is that you learn NOTHING!. as I said "anyone who can write a LCD driver should have no problem with this" By using "examples" and sometimes asking here, you can get much mundane stuff to work, but when you get tasked with a real job, you will be blank. Write some code without using "examples" and make it work, you will learn more in less time. Erik
