I2C (Solved) and Atmel, Zigbee
Greetings everyone,
I am wanting to a wireless project and have been searching around for wireless transcievers with a range that will cover atleast 2km easily. Now thats when I tripped over the wireless section of the atmel website! While assessing the modules their, I have thought of something worth noting for this project;
my project involves an I2C bus with 7-bit addressing to communicate between all the devices, however I have come up with an issue. I can use up to 112 addresses to personalise each device which is fine for the average project, but my project requires 5 to 6 networks of 20 devices minimum which means there is not enough addresses. Thats were I wondering, do the Zigbee and Atmel wireless modules (ATZB-900-B0 is the one I'm looking at) use spread spectrum to reduce interference and allow two transmitters in the transcievers to operate at once? I'm thinking that this may be a way to solve my issue of addressing. Otherwise is there another way to over comne this problem without using 10-bit addressing (ie. some way of software addressing)?
Sorry about the long winded question,
Thanks,
James
