I'd be interested to know how you can do this, unless you write your own =
bootloader.  Are you confusing the fact that the programming on the PIC is =
serial with the fact that their is a serial port on the computer?  The two =
are not the same.  You need two lines to get data into the PIC, one for =
data, one for a clock (plus you need to play with the programming =
voltage).  The data line is bidirectional.  The serial port on a PC has =
one receive and one transmit pin, no clock.  Just because both are serial =
it doesn't mean they are the same.  Like saying I have a digital watch and =
a digital camcorder.  Just because they both operate digitaly doesn't mean =
they can talk to each other. =20

Hi everyone,

Please correct me if I am wrong.  I am a little confused.

Why do we need (to buy) the PIC Start Plus programmer when we can program
the PICmicro In-Circuit through the serial port of a PC?  Isn't it more
convienent to program the IC in circuit than program it on the programmer?

If ICSP can program the same as the PIC Start Plus, which one is faster?
How do I program the PIC in-circuit (I am thinking of getting rid of my =
PIC
Start Plus programmer!)

If my understanding is right, then I think it's a waste of money of buy =
the
PIC Start Plus or any PIC programmer (I currently have one PIC Start Plus
programmer).

Thomas
