Hello,

I am working on a project and I'm trying to figure out how to program a microchip to send a frequency at 900mhz. Do I need to have a certain type of computer? Is there a certain program that I need ?
I was recommended the following site to go for a microchip..

I'm new to electronic projects so any advice will help..

Thank you,

Why do you need that frequency? What are you going to do with it?

It's unlikely that a microprocessor can generate that high a frequency. They operate at a magnitude of ten slower.

XBee is a radio frequency communications protocol. It uses dedicated transmitters/receivers to communicate.

 

I followed your link and found this user's guide:

My guess is it will tell you everything you need to know. You'll probably interface an inexpensive microcontroller with it using the UART interface. This is only for this particular chip, but is representative of what you'll end up doing.

Because from what I read the 900mhz will allow me to reach a transmission radius of 1,000ft, if you think there's a better way I'm open to suggestions..

What do you mean by dedicated transmitter/receiver? Is XBEE not the best way to go about this?

Thank you,

Thank you I will read through it, what's the difference between an inexpensive interface and an expensive one? Aside from the price of course

For communications, the microprocessor (what you program) will talk to a transceiver, like the XBee. You don't program generating the 900mHz signal. That is done in hardware, like the XBee.

I'm just trying to clarify what is done in the microprocessor versus what is done in the XBee.

I said "inexpensive microcontroller." This day and age, there's not reason to spend more than a few bucks for a full-function microcontroller, making for a very cost effective solution to most communication requirements.
