Range with Maxstream - I obtained 3/4 mile (could have been more). Simple test conditions: XBeePro module with little 2 inch whip antenna, held out of car window, talking to their USB module @15 ft elevation. The USB module is another XBeePro with a slightly better antenna. Prett

I don't think that you read the manual correctly. Unless you want some other kind of sleep mode. To quote from the "Sleep" section of the XBee manual: "Sleep Modes enable the RF module to enter states of low-power consumption when not in use. In order to enter Sleep Mode, one of

Thanks for various responses to my original Zigbee question ... Had a quick scan of the XBee Zigbee manual (as opposed to 15.4) and it would appear these modules don't support sleep mode for "end devices" - is this correct, and does it therefore mean that XBee isn't suitable for

Hi, I've written a code with CodeVision, so that two AT90CAN128 can communicate together via TWI. One is the master and the other is slave, which is interrupt-driven. But something is wrong with it, when I send a message to the slave he should ACK it. When I disconnect the SDA li

I did my complete development with the Xbee using TTY serial on my doodads (connected to mega128's). They were pretty easy to use once I figured out how to configure them to do what I wanted. You only need the level shifter if you want to connect to a PC for firmware upgrades (or

Hi Steve, I will also (hopefully) need to use zigbee if things go my way... I am thinking of using the Xbee Pro, because of the higher power. Is it worth buying the development kit, or it's just as easy to buy modules and interface to them (MAX232 or so for PC end, straight seria

The Maxstream ones are popular IMO because they just work. No need to get a special development seat for IAR to program them, they network, they transfer data - In short they are inexpensive and easy to work with. I love them because I don't have to re-invent the wheel to get net

Last time I looked, Atmel's 802.15.4 product did not have an Atmel-supported ZigBee stack and one on the certification track. That's OK if you don't plan to use ZigBee (network routing layer). Also, many/most other module level products have an optional power amplifier to take th

I sudpect they are real, since the Z-link is really a package, a processor combined with an AT86RF230 Zigbee transceiver chip. I have 5 of the AT86RF230 chips in my possession, which I received through Atmel as a pre-release sample for a project that has since stalled )-:. It is

2007-02-07 by Mark Nowell
Does anyone use an Atmel AVR-based Zigbee (Z-Link?) module or know if such things _really_ exist and where I might buy them (in UK)? It seems the MaxStream XBee modules are popular amongst AVRFreaks - perhaps this means the Atmel offering isn't available? Thanks, Mark
2007-02-07 by AVR Development
Thanks John. Um. I fixed it. Apparently, the prototype area, as they all it, has to be manually hooked into the JTAG, ISP, Parallel and Serial Programming, and also the DebugWire thing. I didn't know that. It's working great now thanks :) -----Original Message----- From: AVR-Chat

Apart from "giveio" (which you must): using avrdude, did you find an entry for the programmer in the file "avrdude.conf"? If not, you'll have to add an entry, you may have to reverse engineer (if you don't have the info) which parallel pin goes to which AVR pin (MISO, MOSI, etc),

You mean this one? http://www.lancos.com/prog.html The parallel port is a pain. It is a self inflicted pain when the STK500 and AVRISP are so inexpensive. Lots of places offer $15 more-or-less parallel port programmers as well that work with PonyProg, Avrdude or even Bascom. Ther

Check out the libc FAQ it has many hints/tips for variable optimization (or how to avoid it) and loop stuff. In short you need to be very aware of variables that are modified outside the scope of the C compiler: e.g. interrupts. Then you need to use the "volatile" keyword. I find
