But it takes like 2 seconds to write, another 2 seconds to read back/verify, so that's 4/5 seconds ! ;- Okay, in absolute terms it seems like a very short time. But I sometimes I do a 5 seconds change in the program (change a constant, comment out/uncomment code, what have you), 20 times in a row, so 5 seconds start to feel like eternity ! ;-P I think I am more like anticipating the pain it will be when the program progressively grows and will eventually be nearing the 32KB limit, and I the waiting times will be more like 15 seconds, which will I am sure feel like eternity (for good this time ;-). And if I mose to mega64... 30 seconds, ouch ! So when I read in the avrdude man page, that the JTAG ICE achieved 100KB/s download speed (well, it says 1us bit time, so I did the maths ;-), which is 20 times faster than my DIY ISP cable presently, well JTAG was looking rather promising ! Maybe the Dragon can't go as fast as the JTAG ICE, but even if it manages half the speed, it will still delight me ! > > I understand that JTAg, thanks to its very nature, allows to chain > > devices, allowing to talk with any one dvice from a single JTAG port. > > In practice I don't think the Dragon supports that. :o(((((((( > Solution: buy two Dragons! Hey Dave, you want to bankrupt me or what ?! ;-) I have already spent 200 bucks to import my 240x128 graphic LCD module direct from the manufacturer (Matrix Orbital) in Canada, please let my wallet breathe a bit lol ! ;-) > I have a dead Dragon laying around somewhere.

I blow AVR chips, and you blow Dragons... maybe you should set up a "blowers" club... -- Vince _______________________________________________ AVR-chat mailing list AVR-chat@nongnu.org http://lists.nongnu.org/mailman/listinfo/avr-chat
