hellow.
its 4 days i am working so hard and cant see results.
i am trying to programmig pic16f877a with the eZPIC programmer whice i have built from : **broken link removed**
i use XP and tried icprog and also winpic800.
its just not working. the programmer led is not blinking, and i get eror on the 0000h when verifying... i have checked everything!
maby my port is closed? i have download the driver for icprog.. BUT- when i choose on the icprog a jdm programmer - i cant choose any port from the list (com1,2..) because they are not avaluable! ,thats the way it shoud be????
also -how do i set the feuses ?? i use a crystal on my circuit..
and should the pgm be connected to ground? should i give external 5v to the pic while programming????
whats wrong here? why the programmer's led is not "on" ?
i also checked the voltages on circuit and i have there some voltages..
does some one also know how every pin on the programmer connect to the pic?
please...help me... i am trying so hard!!
thanx !!
