Hello

I have just received STK505 and I'm trying to program attiny44 in High Voltage mode.

Do you know how set the cable and jumper on STK500 or STK505 for program it?

Thanks

The user manual - built into the AVR Studio help system is surely the best reference for this.

In the Studio help: STK505 User Guide -> Programming the AVR.
The help page talks about tiny24, but the procedure is the same for tiny44 as well.

Now work:

Cable
[STK500 prog ctrl] <--->[STK500 port A]

[STK500 prog data] <--->[STK505 hvsprog]

Jumper
Vtarget - aref - reset - xtal --> close
bsel2 - pjump --> open
oscsel = 1-2 close (software)

STK505 switch
both must be on: extclk and reset
