hi evry body

i need a help

i need to communicate between my PC & a pic16f877A

but using serial communication & WIRELESS

cause i am building a care controld by PC

any body can help me plz

i will APPRECIATE any help :P

& 10x a lot for reading this

:?: :?: :?: :?: :?: :?: :?: :?: :?: :?: :?: :?:

Two things: Manchester coding and Serial radio modules.

You can get preasembled radio trasmiters/recivers.In wich you simply drive an serial signal and you get it out on the other side.You dont need high bit rates so go whith an cheap one.

Then the data has to be somehow encoded in a single steram whith the clock in it.This is manchester coding.You shod use an PIC to do it.

yes but i nead the nam off the ICs

i heard about somthing like that but i forgot the nam of the IC

i need a website or the nam of the IC

& offcorse i need a very good signal recived to be readed by the PC or
the PIC

thank u for helping

:roll: :?: :idea:

Its not an IC its an tini circuit bord whith smd components.

It sorts all out for you.You just aply power and drive the signal in and on the other side you only need the power and you get the signal out.

A lot work at 5V levels so you simply conect it to a PIC directly.(I wod use resistors in betwean for safety)

Il post you a picture of how theay look like.

You can also use an IC but you need all sorts of inductors,capatiros,resistors... to make it work.

Someone Electro 10x

but what i needed that if i want to buye it what should i ask for

what is the nam off this small circuit

where can i find it ?

& 10x a lot :P

Thats just one of these modules.

there caled serial radio modules or radio modules.

Just search your component suplyer for these thingys.

try linx technologies. they have many different types of wireless devices and apps.[/url]
