Yeah, sorry about that, I guess upon further review of the page this is
correct and I should not have even asked- I guess I will have to depend on
my breadboarding for now. I do have a coupld of perhaps silly questions
regarding the schematic, such as what are the lines which break with a
circle supposed to run into? Are these to a positive common source which
they all meet/branch from? I assume that the arrows pointing downwards are
the common ground lines? So this programmer gets its power from the hosting
computer, no? and the 13V needed is generated from the? I think that I need
a bit of an explanaition-more than what the page describes, because I don't
know what the charge pump is, looks like a coupld of caps to me and a coupld
of diodes for protection, but I don't know anything so...You mention that
you have a breadboarded version already, how many types of PIC's have you
programmed with it so far, and were there changes to the design that were
necessary to implement programming of certain types? One last question I
have regards the type of PIC used in the programmer, does this PIC have to
be a 16F628, or could one use a PIC18F252 for example? The reason I ask is
that I have one of those EZ-controllers, which is a 18F252 with a serial
bootloader on board, and is able to be programmed with a PC and cable. I was
thinking that I may be able to use this for the PIC in the programmer untill
I can get a coupld of PIC's loaded, then swap out or whatever? Alternatly,
does anyone know if these modules are able to program PIC's other than the
onboard 18F? There is the programming port(three pins) then up atthe top
there are two other sets of three, with an RX and TX, so this could be
doable, no?
