Im going to be using XBees in my project to wirelessly communicate between things, one of the devices is going to have a set of switches and 1 output - the xbee has enough IO to handle it. Is it possible to program the XBee to do the processing instead of having to interface a microcontroller with it? As I'd like to reduce the need of these extra microcontrollers.
The idea of the system is that if a switch that is attached to the xbee is pressed the output is toggled, and then if it is toggled on the remote device, the output is toggled on the device. Is this possible or will I have to use microcontroller as well?
Answer
I don't believe there is any xbee with an integrated micrcocontroller. However, integrating a microcontroller isn't always expensive. Take a look at Ti's line of ValueLine MSP430. They should do what you need and for less than $1 (perhaps even less that 50 cents depending on your requirements). They come in PDIP so they're much easier to use than other SMD microcontrollers.
