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
