Jinx, thank you for your advices, I took them accordingly and they didn't upset me. But I have took a second (or even more) look at that datasheet, and if the pin no. 1 is E I'd say it is an EBC pinning, isn't it ? Anyway, the pinning I have is CBE...

A stitch in time and all that. Not that he needs lessons from me. I've done it. 10 boards that need stuffing, the pupils dilate, and you get stuck in. Then ooops, oh fairycakes, on #9 you realise that a cap is backwards. Or my favourite, which still haunts me - designing a board from the wrong side and all the chips had to go on the solder side. Upside-down with their pins bent over their heads like they're surrendering. Fudge, that was a lot of chips........ -- http://www.piclist.com hint: The PICList is archived three different ways.
