How do I program a PIC 16f84?

Please, how do I program a 16f84 PIC from my pc.It is my first time and I dont know what to connect to what.Can some body pls help me?

there you go brother

Pls Ajay, do I have to make the circuits on those sites to program a PIC?

well to program any controller you always need a circuit and yes you have to make it make the one you like...

Hi Ajay,looks like I need some more help.Can you tell me all that I need to streamline to get a program into the 16f84 PIC.from the text editor to the PIC itself.what do I connect the text editor to and what I connect the text editor to,what do I connect to it etc.where does the assembler come in?where does the hardware come in etc.I really need to get an LED flashing at least.Pls help.

I really do not know what you are asking.. But as i see you want to write and program a PIC microcontroller..
So you need these things..
1. Assembler/Compiler
2. A programmer (or Burner) circuit

You can get assembler from internet.. one of the famous design tool MPLAB is available for free from Microchip website www.microchip.com Just go to Products->Develipment tools->MPLAB IDE

Rest is the hardware which you need to program your IC is available at the top you can make it and directly work on it. Hope i have solved the problem now

erhny,
looks like u already know what is required...
u said assembler text editor ,hardware etc...
as ajay said MPLAB IDE is the best known till that..
it has assembler and programmer integrated to it...
i have a document which is actually a tutorial to mplab ... i'll have to search for it..(not used it for long...:D)
will post as soon as i get...
till then if u r interested in pic c programming go for ccs c compiler demo download or hitech picc download...
these two compilers are pretyy popular here in india....:)

just take a look at this site for further reference.....

the tutorial is okay for beginners..

soon we will have our own pic tutorial pages on this side...
watsay ajay????

u can also dwnload these files for refernce......

Thank you very much Ajay and Shyam.Pls,I would want to know whether 8051's are better than PICs in RF circuits such as RFID security circuits.
