Hi,
I think i've bitten off more than i can chew in my current project, but that's ok because it can be an on going project to keep me out of trouble. I'm new to microcontrollers and know next to nothing about RF/wireless. What I'm trying to do is automate a collection of model cars i have, my plan being to put a microcontroller (most likely a pic) in each car and have them wirelessly recieve instructions about where to drive, what lights to use, etc, from a central unit (another microcontroller). I'm after some sort of star topology network.
The range only has to be around 5meters max.
I think the data rate would be fairly low.
I'd prefer to steer clear of infrared for reliability reasons.
Space is an issue so the chip/components would have to be smd
Price is also an issue (i'm a student)
I've searchd through many websites and i quite like the sound of microchip's MRF49XA, datasheet: https://ww1.microchip.com/downloads/en/DeviceDoc/70590b.pdf , but correct me if i'm wrong it sounds like it only works for connecting 2 microcontrollers not a network.
Any help on the matter would be greatly appreciated.
Thanks
Michael
