It reads the fuses, but then fails to set them. But in AVR Studio you have to read the fuses then set them, you can’t set them by hand then program, this uses my one attempt before the Dragon fails to communicate. So i think, ok reset the fuses since it’ll let me do one operation. It’ll read the chip id once, or read fuses once, then require me to exit the programming software, and reload it. At this speed the Dragon is having problems reading and flashing the chip, even at 51khz which is the lowest speed. However I fail to take into account that CKDIV8 is set ( clock divide by 8). So I select the <4Mhz option and AVR Studio warns me that I won’t be able to program the chip if i set it this low, I say no and put it back on the internal 4Mhz.

Then there is the software itself, the way it interacts with the USB has it disconnect and reconnecting after using the AVR Studio programming interface, sometimes it’ll hang and you’ll hear the USB connect/disconnect cycle until you unplug it ( which increases the chance of the chip blowing up issue ) and exit AVR Studio 4, which is really annoying especially during debugging. My dragon has been repaired three times so far. It has a design flaw that causes a couple of chips to blow up regularly, so regularly in fact we keep a stock of the chips at Null Space Labs.

The dragon is a terrible piece of hardware when it doesn’t work right, which is often. We use the ATTiny2313 which a lot of people complain has no legs ( the MU package ), I think its great but it can be a challenge especially with the milled versions of the PCB to fix and replace the chip.Īnyway I was playing around with different clock speeds in AVR Studio with the Atmel Dragon.

Yesterday I was rewriting code for Null Space Labs ‘Cylon III’, a blinky toy thing we make and use for people to have soldering practice, it spawned from the EMSL Cylon and then through a few iterations from a simple 9 LED thing to a charlieplexed circle.Ĭylon II (with an IR LED to mimic a tv-b-gone)
