Arif, Just for giggles, you may want to look at mote and dust sensor systems. It is much more expensive then RFID but more flexible. It sounds like you are mass producing this and the price would knock the technology out of the running but I though I would bring it up. It may giv

I have found my problem (I think) and learned something about the STK500 as well. First of all, the STK500 can not even read back the firmware version unless you have a working target attached. This is strange to me as It leaves you with no way to even test the rs232 comms to the

Hmm, You know, I have this happen with my Tiny26 boards too. They just start doing something "else" every once and a while and I can't figure out why. In most cases if I hold down the reset while I power the boards on, they work. And the vast majority of the time the boards work

The problem for me is that I have no clue as to what the solution is. Is there some problem with the way I designed my board for the ISP6pin and the JTAG signals. I doublt it as I changed nothing since the last prototyp in that area AND the last pcb had that day last week where i

I am fairly new to the microcontroller. I am very enthusiastic about the Atmel ATMega128. It seems that the Mavric-IIb board gives me just what I need to power my applications. What else will I need to be able to program it to do my bidding. Obviously, I need the Mavric-IIb board

I just buy a AVRISP and alot of ATTINY11. Then I find out that this AVRISP do not support ATTINY11. I think to modify the AVRISP, so it can program ATTINY11, but I don't know to do it. Can anyone please help me ? Thank you Budiman

It doesn't really matter. Size does ;-) Especially for the antenna. I suppose the high frequency tags 13MHz or higher would be best in that aspect. I had a look at the Texas site and they seem to have a lot of useful 13Mhz stuff, but nothing for the UHF band. I only need a simple

Are you interested in the low frequency (magnetically) coupled tags, the 1-bit "anti-theft" tags, the 13MHz system, or the UHF (850-950MHz) tags? Jim On Wed, 6 Apr 2005 13:49:02 +0200 "Jesper Hansen" wrote: > > > > > > While at the RFID stuff...... > > I need a very small tag rea

There was a seriously long delay between the time I posted and the time it got on the board because I might be a spammer. Nevertheless, the Mega32 is still a candidate for other projects and a little more info won't hurt me. But, I understand your point completely! --- In AVR-Cha

No, I have mot. This sort of thing IS planned for EPC Gen3 or Gen4 protocol. Gen2 is just, now, starting to filter out and that has taken well over a year. At this time, EPC is primarily for UHF (850-950MHz) and does NOT deal with 13MHz RFID or 125KHz RFID. Jim On Mon, 4 Apr 2005

Suggestion: Get a development board which supports download of your code via the serial port. Super easy. Download via a wireless link if you wish (I do so via a LANTRONX WiPort using WiFi to high speed serial). The PRLLC Atmega32 is a good one. Comes with serial port bootloader
