Hi I've a new PIC programmer based on 4066/7406... I used it several time and now when I erase a 16F84 the programmer "destoy" it !! One look like erase but can't be programmed. One look like all bits at 0 and not eraseable, and one have a counter that can't increment more that adresse 2 during programing/reading !! Have anybody have a idea about my problem ? Vpp is ok at 13.2V during program/read cycle and Vdd about 4.80V Thanks Sylvain
