    I'm researching as to why I cannot read the chip signature from a ATTiny261 when I can from a ATTiny26.

    I am running CodeVisionAVR on a laptop via a parallel port and it appears to be running on 3.3volt supply being a relatively new laptpp.

    A. Is this causing the issue?
    and
    B. is there another way I can read and progran this chip?

    Error message:
    Can't read chip signature because LB1=0 & LB2=0.
    This is a new blank chip.

    I appreciate any help you can provide.
    Many thanks in advance.

    Looks like the chip is locked. Also does the stk200 support the attiny261?

    If it is indeed locked then you'll have to do a chip erase then check the signature and program
