> >To make it short, it was pretty obvious it died. A helpful failure indicator is built-in. It is activated if you use high enough current or voltage. The indication is auditive, olfactive and visual, as well as physical (if a flying piece of the chip hits you). To achieve activation of these functions, use at least 24V supply. Lead acid and NiCd batteries are highly recommended. Lacking that use 220V or better 380V mains. Peter -- http://www.piclist.com#nomail Going offline?
