Hi all,

I need suggestions on icsp a pic using another pic.  I have written my own
icsp program for windows, and have adapted it to run in a pic.  I've
captured the programming process on a meter, and everything looks as it
should.  bits are being clocked out right when they should be, etc.  BUT,
when the read command is issued, the pic being programming responds with 14
ones.

Also, I've tried just issuing the bulk erase command to see if the commands
are being received, and it appears that they are not because the pic is not
erased.

It's like the only command being received is the read command because the
pic responds to it. Or, is this a fluke thing?

Anyway, any advice would be much appreciated.  I've tried all timing from
the minimums in the spec sheet all the way up into the milliseconds with no
results.

The pic I am programming is a 12f675.  I'm using a 16f877a to do the
programming.

Thanks,

Jim Monteith
