I did read through that, but it shows programming another Arduino or programming a chip on a breadboard, i am dealing with trying to program a 1280 SMD installed on an existing board with an ICSP 6 pin header. So thats where i got lost.I have a boot file for the 1280, i found all the info and files to do this on a 3d printer forum, the problem is they are all using a standalone USB programmer which i do not have, i bought one but its going to take weeks to get here, so i was hoping to do it with the Arduino if i can to avoid the wait. Interesting.Ok, so its possible to do with the UNO, now the question is how do i wire this up. I have found a bunch of posts on this subject, some mention wiring from the ICSP port on the UNO to the ICSP port of the board you want to program, in my case a Mightyboard from the 3d printer, and then run the reset line over to D10.

And yet other posts mention wiring the ICSP port of the board your trying to program to various pins on the UNO, and adding a capacitor or a resistor, etc etc. Its all very confusing because every post i find on it they did something completely different.Just looking for the magical formula that actually works!
Well i followed every tutorial i can find on the subject. NONE of them work.I just get an error from AVRDude saying that libusb0.dll is missing. So how the heck do i fix that?
I installed the Arduino software latest version on my workbench computer and connected the UNO, it saw it, installed the drivers, and its on COM6, i can read and write to the Arduino. I uploaded the ISP sketch, grabbed my breadboard and wired the pins as shown in the sketch using the breadboard as a breakout to add the 10uf capacitor thats needed on the reset line, connected pins 10-13 to the ICSP header on the Mightyboard, powered up the mightyboard and tried the AVRDude command and it returnsLIBUSB0.DLL NOT FOUND REINSTALL BLAH BLAH BLAHSo now what? Ok i got past the USB problem but then when i issue the command i get this.C:avrdude.exe -p m1280 -P COM6 -c avrisp -U flash:w:C:ATmegaBOOT168atmega1280.hex:iavrdude.exe: AVR device initialized and ready to accept instructionsReading ################################################## 100% 0.02savrdude.exe: Device signature = 0x000000avrdude.exe: Yikes! Invalid device signature.Double check connections and try again, or use -F to overridethis check.avrdude.exe done. Thank you.C:So how do i get past this and whats the -F to override. So is this chip just hosed or what??C:avrdude.exe -p m1280 -F -P COM6 -b 19200 -c avrisp -u -U efuse:w:0xF5:m -Uhfuse:w:0xDA:m -U lfuse:w:0xFF:mavrdude.exe: AVR device initialized and ready to accept instructionsReading ################################################## 100% 0.06savrdude.exe: Device signature = 0x000000avrdude.exe: Yikes!
