This is very similar to what I was having. I could programme the device using ISP mode from the JTAG ICE MKII but could not do it from the ISP. I re-flashed it and it started working again. No idea why it was like that in the first place as I had never used it from new. Good luck

Bit of a long shot, but someone here may have these parts sitting on a shelf.... Basically I require approx 350 parts each of the following to complete an order: Avago HSDL-7001 IR decode/encode TFDU6102-TT3 IR transceiver It would appear that these are discontinued and a redesig

Oh sorry, I got rid of the blinking orange when I did the manual upgrade the other day. I got back to the green light but it still won't work none the less. I'll take a look at that Dragon too though, sound like a good deal. I appreciate all the info on this. ----- Original Messa

Yeah I actually ran through the manual upgrade already. The AVRISP2 must be bad, I can't get it to connect to any of these chips and everyone else seems to be out of ideas. If they'll give me my money back I'll just grab a USPS flat rate box and send it back for 5 bucks. I'm not

That's seems like great advice, But I've never done a thing like that before (reminds me of a nice song ;-) ... so it will take me some time to figure it out, unless you'd show me how, seeing that you're already so involved :-) OR, I suppose I can just put the whole assembly in t

Thank you Don, In the mean time I looked at the lss file and it looks like I should also save R24. I didn't know but it looks like SREG is saved through the use of another register (can't push directly). Apart from that, I suppose only the Rxx that are inside the ISR in the lss f

You can beat that price: AVR ISP II is about $35 at Digikey. Pololu AVR ISP is $20 (emulates AVR ISP II with other cool stuff). AVR STK500 is $80 at Digikey both parallel and ISP programmer. Those are all what I consider very affordable. DLC > You can get an JTAGICE mkII for half

You can get an JTAGICE mkII for half price at Arrow electronics. Inside the U.S., price including shipping is about $160. Whether or not that is "affordable" is your decision. Offer is at: http://www.arrownac.com/manufacturers/atmel/s/avr/#design-smart Check the link at the very

I think I'm talking about using "ISR_NAKED" as an attribute, but how do I do that? For example, if this is my code: >>> ISR(PCINT0_vect) { if(bit_is_set(PINB,PORTB2)) { SPCR = 0; ui8Status = 1; } } To: avr-chat@yahoogroups.com > From: catalin_cluj@hotmail.com > Date: Wed, 20 Jan

Hi, I seem to remember that there's a way to tell the compiler to not do context saving/restoring when going into an ISR on ATMega chips (I know XMegas, etc can do it, I'm only interested in the ATMega now). Am I dreaming, or is it possible? Or is it only possible in assembly, in

Sorry guess my other message was kind of confusing. Well I found a test clip I had bought for this and forgot about. So another new chip put into the test clip. Everything hooked up correctly, 100% sure. 10k between reset and vcc. Power up chip, power up isp, avr studio reads 5V

It is bad to assume anything. It causes problems. Most switches are break before make. The make before break also cost more. But dont relay on price to decide. If you don't have a datasheet you will have to do tests to find out what it is. Brian --- In AVR-Chat@yahoogroups.com, "
