Im doing one of my subject's project that involve in connecting atmel 8051 (model 89c51) microcontroller to Maxstream RF tranceiver. the microcontroller is responsible to send data to this RF tranceiver. below are questions: 1. how many pins from microcontroler connected to this RF transceiver (only RxD and Txd)?? 2. the RF baud rate is 19200, does it mean that the microcontroller also have to set it's baud rate to 19200? 3. does anybody have such source code?? kindly send to me. thanks alot
1. how many pins from microcontroler connected to this RF transceiver (only RxD and Txd)?? see transciever manual 2. the RF baud rate is 19200, does it mean that the microcontroller also have to set it's baud rate to 19200? If you have to ask that, what are you doing making projects. < i>3. does anybody have such source code?? kindly send to me. Help is free, doing your project for you will cost you. Send specs and you will get a qoute. Rrik
"1. how many pins from microcontroler connected to this RF transceiver (only RxD and Txd)??" See the RF transceiver's Documentation "2. the RF baud rate is 19200, does it mean that the microcontroller also have to set its baud rate to 19200?" Not necessarily. It is possible that the module may be able to communicate with the microcontroller at a rate different from its RF link speed. The only way to find out is by reading the RF transceiver's Documentation "3. does anybody have such source code??" How about asking the module manufacturer and/or distributor? In short, none of this has anything to do with the Keil tools at all!
