I was reading through a bunch of threads, such as this onehttp://www.societyofrobots.com/robotforum/index.php?topic=104.0
but it seems my questions are still up in the air.
Here are my basic questions, if you guys could guide me in the right direction I'd be grateful
1) Whats the best/easiest method to use UART between a an AVR MCU and a laptop (using a USB port). I just want sensor values to print out to something like hyper terminal.
Any good recommendations for a TTL -> USB conversion? Any hardware you can recommend?
2) Whats the best/easiest way to do the said above wirelessly? Bluetooth, easy radio, what?
3) Whats the best/easiest to program an AVR wirelessly and to communicate values
TTL -> USB -> Bluetooth? -> USB ?
4) Whats the best/easiest way to get to AVR chips to communicate wirelessly. For this one, I only want one AVR chip to send a updating value to another AVR. Example, the voltage that the transmitting AVR is reading on one of its ADC channels.
TTL -> bluetooth? -> TTL
I've read the UART/bluetooth tutorials, but they don't into much detail about hardware it seems. I was hoping some of you will have some experience behind you to answer my questions.
Thanks for any guidance, links that anyone can provide.
Does anyone have any experiences with using AVR integrated wireless chips? http://www.atmel.com/products/zigbee/default.asphttp://www.atmel.com/dyn/products/devices.asp?family_id=676
Are they good? I'm trying to decide between using general RF or trying ATMEL's solution. So far I've been really happy with their products.
