Yeah dude, this is very common. I myself have to use my new desktop to program with my noppp. My laptop puts out just under 4 volts. I could use different diodes and get it to work, but Radio Shack no longer carries 1n34's and I don't need to order anything else. Sometimes buying an extra lpt card will help if you are using a desktop (or if you are like me and like to hook up dangerous stuff to our puter). -----Original Message----- From: pic microcontroller discussion list [mailto:PICLIST@MITVMA.MIT.EDU]On Behalf Of Jim Sent: Tuesday, May 14, 2002 11:07 AM To: PICLIST@MITVMA.MIT.EDU Subject: Re: [PIC]:parallel port? FPP programmer help Well after pulling my hair out for a while I found that my parallel port put out 3v for a high is this normal. I'v been looking around the web at parallel port spec's nad didn't find anything about voltages on the parallel port so I am assuming that it's suppost to be 5v for a high. Can anyone tell me if 3v is correct for a high?.
