i am a total noobie to programming of any kind and have selected the avr as my chosen platform i purchased the stk500 starter kit and then produced an add on board which contains a 40 pin zif socket and an iso wafer card slot and wired these to the stk via the 10pinisp header in the hope that i could program these target devices externally the problem is i am unable to erase/program/signature read the atmega8515/at90s8515 using this method but when the ic,s are placed in there onboard sockets all,s ok i thought due to the stk having an onboard isp this would,nt be a problem but cant seem to find the cause i have searched endlessly for a solution but alot of the links refer only to atmels avrisp standalone programmer and there documentation in the user guide only shows isp being used via the onboard sockets have i got it completely wrong.
additionaly when using studio and selecting isp as the programming method is the software then looking for the external avrisp interface or running through the stk500 and using the onboard isp
any assistance welcome
please consider when replying (be gentle) that my learning curve at this moment is a true vertical :lol: :lol: :lol:
thanks in advance
