This is an emergency release of my AVR programmer.<br>
Emergency, because many people have asked for it, and because I need to refer to it from the <a href="http://www.myplace.nu/mp3/yampp3_2.htm">assembly instructions</a> for <a href="http://www.myplace.nu/mp3/yampp3.htm">yampp-3</a>.
<p>
</p><p>
The program works great, but it still lack some features like fuses and stuff.<br>
On the other hand, it offers some unique features :
</p><p>
</p><ul>
<li>Built in Serial Terminal</li>
<li>Built in SPI Terminal</li>
<li>some more, I guess.</li>
</ul>

So far, there's no help, so you're on your own. However, it should be quite easy to understand how it works.
</p><p>
It's project based, and uses autodetection to determine device type. It supports the following devices so far :
</p><pre>AT90S1200
ATtiny12 ATtiny15 ATtiny26
AT90S2313 AT90S2323 AT90S2333 AT90S2343
AT90S4414 AT90S4433 AT90S4434
AT90S8515 AT90S8535
ATmega103 ATmega161 ATmega162 ATmega162 ATmega8515 ATmega8
</pre>
<p>
It uses the PC's parallel port for interfacing to the target and supports three different interfaces :
</p><ul>
<li><b>My own original interface, using only 5 resistors.</b></li>
<ul><li type="square">
This interface is supersimple and uses only 5 resistors. But it will
load the circuit so the plug will have to be removed when the target is
running. </li></ul>
<br>
<li><b>The Kanda STK-200/STK-300 dongle.</b></li>
<ul><li type="square">
This is the "classic" dongle supplied with the STK-200 and STK-300
evaluation boards. The plug can normally remain connected when the
target is running. </li></ul>
<br>
<li><b>An Altera/JTAG compatible interface.</b></li>
<ul><li type="square">
This interface is is similar to the dongle, but is compatible with the
Altera ByteBlaster cable (with a different pinout, though) and can be
used with Altera's MAX+plus and E-Max+ programs for programming the MAX
and FLEX devices.</li></ul>
</ul>

<p>
It needs the DLPortIO driver to access the parallel port in Windows,
and runs fine on Windows 98 and Windows 2000. It should also
run on Windows 95 and Windows NT (should anyone have forgotten to
upgrade).
</p><p>
There's probably a billion improvements you'd like to see in the program, and hopefully not as many bugs.<br>
Whatever it is - let it all out to <a href="mailto:jesperh@telia.com">jesperh@telia.com</a>. Who knows ? Maybe you'll
see YOUR suggestion in the next version <font size="-6"><i>(if you're bloody lucky and I've got the time ;-)</i></font>.
