Looking for some info on in line serial programming - rigelscout - Nov 6 12:58:00 2003
Howdy,
I looking for some info. I've created a small device with a 2313. It
is using the USB module with the FTDI chip on it and working great.
Now I'd like to be able to upgrade the code on the avr if I need to
without taking it apart and pulling it out.
Anyone have any suggestions on doing the in circuit programming on
the avr?
Thanks Karl

You'll be much better off, to switch to the mega-8, so you don't need external hardware to re-write the program space.
If the processor you're using dosen't support the SPM instruction, then you have to use external hardware, basically another processor..
I'm doing this with a M128, and actually the system is much more complicated than that, because there are three other processors connected to that M128, which also get their code reloaded this way.

Well ASSUMING you don't have those pins connected to anything that
will affect this, you can solder together a teeny-tiny board with
long pins sticking out the bottom that will contact the pins on the
chip you need for programming (along with some pins on the other side
that are basically just there to help hold it on.)

If you changed the design to use a Mega8 instead of the 2313,
then apart from the fact that you would get a real SPI, you could
use the bootloader for the upgrade. With the 2313 should be possible
to have another similar programmer to program the programmer
(confused??) as the 6 (or 10) pin programming socket is 1 to 1,
except for Mosi and Miso which you may have to invert in one of
the programmers. If a real SPI was used then the pin reversal would
occur automatically.

hi karl
You can have a look at the schematics for ISP Programming Dongle and its connection with the AT90s2313. http://users.netonecom.net/~bbcat/hobby.shtml
happy hacking
