I have been able to cut some simple code for a PIC, though I am still a rank beginner.
From another forum I was provided with some hex for a project which I needed to write to a 12F675. I have a Vellerman 8048 programmer; I was using the Vellerman ProgPic2 code, and worked out that I needed to 'load' the hex file and then write it. XP is the OS.
My first attempts didn't work - incompatible serial port, and I'm not sure that I copied the hex correctly - but then I found an old laptop that seemed to recognise the programmer. I think I wrote the hex to a pic, but when I tried to read that pic the programmer board would not recognise that there was a pic onboard. I could recognise an unwritten pic in my programmer, but whatever I had done to the first one seemed to have left it uncontactable.
I think I was able to erase it using WinPIC, but this didn't get it recognised again. Have I ruined it somehow, or can someone suggest a way to talk to it again?
