> Good catch, Wouter - I had missed that. I don't use LVP (I am a happy > WISP628 user), so that should not matter, right? No, that is not generally true. To avoid all trouble, connect the targets LVP pin to the appropriate Wisp628 line. For a socket that must accept PICs that have LVP on different pins include a small diode (1n4148) from each such pin to the Wisp628 LVP-pulldown line.
