This popped up last week on an engineering news letter. For those on the list who are into robots check out http://elm-chan.org/works/ltc/report.html He even has a couple short videos of the thing in action. Very clever and cute! (Now I know what to do with my kids cell phones) B

I have not tried the ISP cable below but I do use (since last night) the ISP cable described on page 33 of the AVR Robot Controller 1.1 which is used in the SRS Workshop Robot. ----- Original Message ----- From: txt me To: AVR-Chat@yahoogroups.com Sent: Sunday, May 28, 2006 9:58

I am personally thinking of buying the AVR-USB-JTAG OPTOISOLATED USB JTAG DONGLE FOR PROGRAMMING AND EMULATION as shown at http://www.olimex.com/dev/index.html It is available from various suppliers. Has any one had any experience with using this unit? ___________________________

I zapped the fuses on the AT90USB1287 that comes with the STK525 and now the Flip bootloader doesn't work. I tried obvious combinations of fuse setting after reprogramming with "bl_usb.a90", but I can't get Flip to load code into the AVR. Flip tells me "Device protection is set"!

Heck, I've litterally soldered HUNDREDS of Mega128 to pc boards with just the above tools. A piece of cake and I've NEVER damaged either board nor Mega.... Same here. NO big deal, flood and braid. Welcome to the dark side, enjoy! :)
2006-05-25 by kernels_nz
Agreed, soldering TQFP packages by hand is just not that hard, I do as ken says, and then also use desoldering braid to clean up bridges between the pins afterwards. Very easy, especially if your only doing 1 board ! Also, welcome to the AVR DARK SIDE , many underestimate the pow

For my next project, I'm fairly convinced that there are no reasonable PIC solutions that fulfill my requirements so I'm ready to switch over to the AVRs. I need at a minimum 46 I/Os, which Microchip accommodates fairly easily but Atmel doesn't seem to have anything between 35 an

No experience, but 2048 samples seems a bit shallow. I am using the Cleverscope, which is NOT a logic analyzer, but has a 2 mega-sample deep buffer. They claim they are adding protocol decode & triggering which will help me out immensely when it is available. As it is I can trigg
