How to make a connection from pic16f84 to computer?

[newbie86]

Hi all..im newbie here...i want to ask about...
How to make a connection from output pic16f84 to computer?
can it connect by USB?
the reason why i want to make this connection is..to activate a software at pc by output from pic16f84 when movement sensor detect at pic 16f84 input..please somebody help me...

Use RS232 instead, check my tutorials for details.

RS323?it is a device?please Nigel Goodwin...can you teach me step by step...im just a kid in this subject...

That's why you need to read my tutorial.

RS232 is the serial port on a PC.

im still dont fully understand about RS 232 to make connection from output pic16f84 to computer...could someone please help me...next week i have to submit them..

In simply PIC output cannot connect directly to computers serial port. It has some different logic levels needed. What you need is a serial level converter (Ex: MAX232) which makes required logic levels to PC input.

PIC output-->MAX232--->PC Serial Port

Hardware is not sufficient it needs a good coding as well the PIC you are talking which doesn’t have built in communication modules (USART).you have to write a software for that modules as well.

That’s why Nigel suggested his tutorials he is using I think PIC16F628A which has a built in communication module.

This also will help you

I feel for you Nigel

Google is your friend... perhaps there is some... slim chance... that someone, somewhere has tried to connect a PIC to a PC. By RS232 which narrows it down slightly.

Huh... Google "PIC rs232" only was only able to find 1,240,000 hits on how to do that. If only one of them shows how to actually do that...[SIZE=-1][/SIZE]
