| it is a single chip microcomputer with flash memory and ADs .from microchip inc., ,you can get sample programs in the mplab installation software pack.

Hi,
Just do a search on Elektroda : "pic" , "pic mcu" , "pic micro", "pic basic", "icd" , "microchip", "pic books", "pic programmer" etc. you'll find all you want to know (and even more!)
Also you could start with this link :

Regards
Hugo

Hi, first of all. For hardware aspects, you need a resistor and cap as a minimal oscillator configuration. If your timing is critical, then you should consider crystal.
For flash PIC, you should consider a RJ connector on your PIC16F877 design, for use with third party debugger (which is used to program your PIC also).
For software point of view, I wouldn't want to work on assembly language anymore, though the assembler is free from Microchip. Try C compiler from third parties like CCS PCWH  It is widely available in the www ( check out on overnet network). CCS website has a PIC forum whereby people discuss anything on PICs. Do check it out
There is a PIC C book for CCS C compiler. You can get it here at ebook here

Hello,
Microchip Datasheets are very well written, read it through first.
You might want to begin by writing some simple assembly program, flash some Leds or something, to make sure the chip, programmer and everything else is working.
Next Try Hi-Tech PICC Lite (C compiler)

read datasheet in this link:http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1434 on pic16f877. Learn the architecture of the pic16f877 throughly.
At the end of the datasheet there is an assembler command set.
Try to understand these commands. Look at this link: http://www.mstracey.btinternet.co.uk/pictutorial/picmain.htm; you can learn how to use some assebler commands. After that search the internet for the applications and examine some applications.

| I believe you will get some very useful site if you do a Google search, with the key words ‘pic tutorial’.

Please decide which language you want to use, assembly or C?
If U start from C can search about Hitech or CCS compiler.

But I would suggest you to start in assembly, there are application notes in Microchip's web site to have you started. By using assembly language, you will having a change to look deeply into PIC's architecture. You may need to download MPLAB IDE from Microchip's website. Good new is it's free.

Hi Aphy,
I agree with Virus. Starts using assembly.
I indicate this site:
http://www.tanzilli.com/?id=207
There are many simple examples to starts with PIC and has a very good tutorial.
Wil.

if u want to play with the 877 u should start reading the EPE magazine . almost all of the projects in EPE are with the 877. i remember an EPE mini tutorial that came with the October 1999 issue of EPE, it was also based on the 87x series of microcontrollers.
for lots of PIC codes go to http://www.piclist.com
and for some great tutorials on the PIC go to Nigel Goodwin's site http://www.winpicprog.co.uk
as for the choice of programming language ill leave that decision to u. its all up to you. some people prefer assembly and some prefer C. actually C is just an abstraction of assembly. some people think that for programming a chip with such a small architecture, C is just too much. u dont need a high level abstraction of assembly when u can easily write code in assembly. while some say that a single line of code in C is equivalent to a hundered lines of code of assembly. as i said the choice is yours.
i use assembly for PIC because it just works for me. when i work with x86 processors i stick with C 
i hope that helps
