So, after two nights spent with my soldering pistol, and multimeter, I realized, I just can't get this thing to work!
I have bought an (two, more exactly) ATMEGA8515-16PU microcontroller, and I would like to program it with my Intel 2,4Ghz PC. I've WinXP installed with giveio.sys. I have built the SP12 ISP cable, and made the connections available there,
2 --> 8 (SCK)
3 --> 9 (RESET)
4-8 --> 1 (VCC)
9 --> 6 (MOSI)
11 --> 7 (MISO)
25 --> 20 (GND)
GND --> 27pf --> 18 --> 4Mhz Chrystal --> 19 --> 27 pf --> GND
But when I try to program it, nothing happens. I have tried to tie a LED between VCC and GND, try the programmer, this way the LED should blink, but nothing happens!
I have checked in BIOS, the LPT was in SPP mode
I thought maybe my LPT port was damaged, so I tried it out on my linux box, doesn't work there either.
I used the software provided there, ponyprog, avrdude and avrsp, nothing works :((
avrdude.exe: AVR device not responding
avrdude.exe: initialization failed, rc=-1
Double check connections and try again, or use -F to override
avrdude.exe done. Thank you.
PonyProg: "Unknown device, or device missing" (used DT-006 I/O)
AvrSP: "No ISP adapter on port LPT1"
Please, tell me people, what am I missing? (And I know it is some little thing so that I can bang my head into the wall when I realize it...)
