'[AVR:] Tiny11 Programmer'

While the Tiny11s are on the way, it would be a good time to do a
programmer for Tiny11!

Does anyone has pointers?

       I built the parallel programmer from here:

       http://elm-chan.org/works/avrx/report_e.html

       Tested it on a 8515, 2313 and Mega8. Worked 100%.

Looks like we could use this one: http://elm-chan.org/works/avrx/avrxp8.png

Only special component required would be the pre-biased transistors or
use resistors with transistors.

Chetan

Does that work with devices like the ATTiny11 that need high voltage
programming?

The schematic shows it having a switched 12v supply to the reset line, so
YES.

Add 4 resistors - one in each base connection, and almost any small signal
NPN or PNP transistors as appropriate would work.  I'd use BC337 / BC327 but
YMMV.

       I used BC547 and BC557 and a 78L05 for the +5V. The base resistors
are in the schematic. The software is the AVRXP.COM that runs in a DOS
window. It is a command line program and can be called as a TextPad Tool.
       The windows version, AVRSP.EXE don't work with the parallel
programmer, but the C source code is available.

Mark,

Were you able to find the Toshiba diode 1SS319 or did you substitute
it with some other one?

Chetan

       I used a BAT85 I had in my junk box. I guess any diode would do.

I have a reel of 1N4148 so it shouldn't be an issue. I found the
datasheet of 1SS319, it is a dual diode package.

Hi Mark,

Can you please try this programmer with Tiny11s once you get them?
