open you're AVRstudio and go to advance and click READ SIGNATURE. that will detect your STK500 and detect what chip is plug into it. then go to FUSES and you will see what fuses are set and not set in the chip you plug into the STK. :) -jay John Johnson wrote: If there is a check

Thanks. Nr 2 looks best for me since I do not plan to attempt in-circuit programming at this point in time. I assume that this is compatable with AVR studio? Erikc - firewevr@airmail.net /// "An Fhirinne in aghaidh an tSaoil." "The Truth against the World." -- Bardic Motto -----

Don't some of them have to be cleared by erasing the chip and eeprom? Are there some that can only be cleared using high-voltage parallel programming? Regards, JJ On Friday, Apr 16, 2004, at 13:24 US/Eastern, Mike Bronosky wrote: > Can be set and cleared at will! > > ----- Origin

If there is a check mark in the box, the fuse is set. It is also "0". Regards, JJ On Friday, Apr 16, 2004, at 09:09 US/Eastern, chrisatwan2000 wrote: > I thought looking at the fuses in AVR Studio was the way to check > what fuses were set. How do I check to see what fuses are se

Thanks. I'm just getting started in AVR so there's a lot for me to learn. My first project is to use an AT90S1200 to read an incremental encoder and display its position on an LED display. Later on, I want to send that data to the outside world; for that I will probably need an A

Typically, the LED BL needs around 4.3 V so the drop from the transistor will put you right about there. You could also configure it as an emitter follower and avoid the resistor altogether. I do exactly this for the same purpose (switching on LED backlight in an LCD display) - w
