I need to transmit about ((11 bits)X 12 devices) of data. I thought of using Xbee module as it is but it has only 7 digital pins.I need to use a microcontroller at the source and destination to decode the serial data.
Are there any ways other Xbee. Can I use RF modules or something like that for each device. Will I get interference from other devices?
Perhaps send the data in serial, rather than parallel form?
Or, convert the 11 bits to 7 bits and use the Xbee. Using two Xbee's at once wouldn't work, because you'd probably end up communicating with two devices simultaneously.
The panStamp project also provides the necessary libraries, communication stack and software tools to develop new devices, configure wireless networks and connect them to the IP world.
