I'm looking advice for PIC16F877A. Which IDE you're using to Program PIC in assembly language MPLAB or MPLABX?

Which one would you recommend for beginner ?

 

MPLABX gets very messy with assembly since V3.x I would use MPLAB8.xx as it has still support for MPASMWIN

You can still use "other" IDE's.. such as Eclipse or TextPad...

I have Proteus, so I always use their VisualStudio...

 

I second the idea of using the older versions of MPLAB, before the 'X' version for assembly coding.
Simple and works well, then they ruined it...

 

For Assembly, I also use/prefer the IDE v8.92.

 

One more vote for 8.xx
I made the mistake of beginning to migrate some clients' assembly language projects to X for future-proofing. Mistake. 8.xx has better WATCH window functionality for assembler and later versions of X now have killed the excellent MPASMWIN in favor of the stripped down assembler used by XC compilers. Stick with 8.xx while you can.

 

Please suggest some good documents and link where to find user manual and instruction set for pic16f877a

 

The obvious to start with.

Data sheet has all!! However!! if you can get the pic16f887.. You'll really like that chip.. Tons more features, cheaper AND internal clock source...
