PIC 877 and Rf wireless

Started by ramtec73 November 27, 2003
Has anyone tried transferring datas to or from 877 wireless. I have
wireless rx and tx from www.laipacinc.com.

Do we the UART for this? Any examples out there about using UART.

Are you sure about that URI? That domain is not registered.
Perhaps if we knew what you were using someone could offer some
guidance.


I think the correct URL is:

http://www.laipac.com/

wow, these are really inexpensive - $20 US for a 916.5 Mhz
transmit/receive pair and cheaper for the 400 mhz bands. It looks
like you just hookup RX and/or TX from the USART. I know some
encoding schemes require that you manipulate transmitted data in such
a way as to avoid certain code words but that would be a small price
to pay for very low cost data transmission. A lot cheaper than
adding WiFi...

I'd love to hear from some one that has actually used these things -
I can think of a lot of applications.

I am trying to transmit data wirelessly on to a LCD. Using a 877 to transmit temperature data through the RF transmitter then receiver picks it up and sends it to another PIC where the temp is displayed.

The 877 should do all the calculation, and the other? 16F84? should just receive and display the temp on to the LCD.

Hopefully this will help.

Thanks
