Hallo All,
I want to program a board containing Atmega 168 and the board has a 6-pin interface(that is an ISP interface).
How can i connect my stk600 for high voltage programming having 10-pins inetrface to my board which is having just 6-pins interface.

thanks for your help in advance

chris

HVPP takes a lot more than 10 pins and it can only really be used if you can take the 168 out of a socket on your board and plug it into the STK600 - most board designs will not appreciate having +12V applied to _RESET and it's almost impossible to ensure that all the lines involved aren't loaded by other things.

Why do you think you need to use HVPP anyway - for a 168 it should only be necessary if you change RSTDISBL

EDIT: The following is the diagram from the Dragon user manual showing the HVPP connections for a mega168. Ignore most of the picture but note how many of the pins for "Device" are coloured connections showing that they are used during HV programming - it's a whole lot more than 10!

And here is the applicable figure from the data sheet. Notice that 18 pins needs to be connected, not counting supply and ground pins.

I wonder if the OP is simply asking about a 6-to-10 pin ISP cable converter in fact?

Well, we won't know until he shows up again, but...

OP has a small history of cross-posting and not reacting to answers. We might have answered in vain and probably just wasted out time.

oh!! thanks very much for your help. i tried to program atmega 168 through ISP interface but the programming phase failed( with response: entering programming mode failed ) and i assumed ,maybe the controller is locked!.
so i was thinking as alternative ,high voltage programming to execute. and i was trying to find out ,if its possible to adapt the ISP interface(6-pins) to the 10-pins on the STK 600 for high voltage programming.

thanks once more

That's the second time you have linked "10 pins" and "high voltage programming". I don't know what has put this thought into you mind (certainly nothing in the STK600 user manual!) but you are quite wrong. Atmel has two different connections for ISP. One is a 6 pin (2x3) header and the other is 10 pin (2x5). They also use a 10 pin (2x5) header for JTAG too (programming or debug). But there's no such common header for HVP - as stated a couple of times in this thread it takes almost 20 connections to the chip to do it and this means that for most "in circuit" designs it's simply not practical to make all the connections.

The STK600 is "clever" (well cleverer than the STK500) because it uses "routing cards" and they hide the ~20 connections that need to be made for HVP but that only works for a socketed chip that sits in the ZIF socket that is on top of the routing card.

You can't.

You postings are etched into the InterWeb for all eternity. Scary, huh?!

I don't think even moderators have the power to remove all traces of you. Only the system administrators might have those powers.

You might have luck sending a PM to an Administrator, eg AVRfreaks user 'Eivind'.

How did you get on with your HVPP?
