avr programming with avrdude and bsd

Hi



I have a bsd (LPT) programmer for avrdude and it works in my old computer (200MHz). But the programmer does not work in my new computer. I guess the LPT signals are more stronger in old machine than in my new computer?



I would like to modify my bsd progammer so that it works in my new computer and is safe to use.



I have 1K resistors in signal lines. Are they ok or can change them to smaller ones? Like 330Ohm?



My cable is a bit too long 120cm. What would be the good length? I guess something like 50cm?



Can someone help me with this?



BR, Indrek

Is the programmer powered by the LPT, if so it might be advisable to use a seperate supply. Post a circuit/URL somewhere

If the old one was XP and the new one is Vista, no chance.

Hi Martin

It is the simplest bsd with 1K resistors for signal lines, 10K for reset one 10uF for power. I use external power, and before 10uF cond I have 78L05 (100mA) regulator. And nothing else.

Yesterday I connected the AVCC as well, before it was open. (It worked with my old machine)

I think that I have somewere the PCB as well. But I have to look for it :-)

Hi John

Unfortunately, I use Linux already 10 years. Both of my machine run Debian Etch.
