PIC16F877 to PC via max232 HELP!!

Hi Terry,

Yeah, I'd love to do Assembler as well. I was 2nd in my class when I graduated in '83. And most importantly, I actually loved writing in Assembler, it came naturally.

But a few, ahem, years have gone by since then and I haven't touched Assembler since. I figure I'll get back into it slowly, once I get this project done. Assembler is the best way to go, total control. But I'm taking WAY longer than originally anticipated when I started this. I didn't even expect to program MCUs when I decided to make my little controller; just buttons and LEDs. Yeah, right...

Ok, so I knew nothing of electronics when I started 18 months ago, but hey, I'm managing. LOL I'm a little slow in some areas (like 99%), but once I get something going, I keep building on it. I'll stick to BASIC Pro for now, since BASIC was the 1st language I learned, and that was, ahem, the day it came out.

Fortran, Pascal, RPG, COBOL, name the oldies, I've done them. It's the new generation languages from C and up that I lack. I never thought I'd say that I wished I knew Assembler on the tip of my fingers again though...

wow, this thread has been extremely useful, but i have a follow-up question..
i noticed that the crystal that loredana used was a 20MHz, i just wanna know what the maximum baud rate is for this crystal and also for the 4MHz crystal?
thanks so much!!! ^_^

Based on internal USART: all will depend wich BRG setting you're using and % error you want to deal with..

Let's say PIC16F877 @20MHZ, all the answers are in the datasheet section 10 Table 10-4. Like every PIC that have USART.
