It seems likely that the DIY schematics is more or less identical
to the official AT89ISP cable since the only signaling difference is
the inversion of the reset - something the PC program can directly
handle.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: programmer circuits</title><link>https://community.arm.com/thread/138899?ContentTypeID=1</link><pubDate>Thu, 18 Sep 2008 01:45:47 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:eeb19def-a415-45f9-81d1-e317fac657eb</guid><dc:creator>edPer Westermark</dc:creator><description>&lt;p&gt;&lt;p&gt;
There seems to have once been a description of this cable, i.e.
how it was connected. The related link is just the pinout of the ISP
side - not the corresponding parallel port pins.&lt;/p&gt;

&lt;p&gt;
There are links to be found on the net, but the document seems to
have been pulled from the Atmel site.&lt;/p&gt;

&lt;p&gt;
I did contact Atmel support for the nordic countries last year
about it, since I then was in very big need of a cable in a hurry.
They could not produce the document or a supplier in Sweden. But
their suggested workaround was to invert the reset signal and use a
AVR SDK500 kit.&lt;/p&gt;

&lt;p&gt;
If I need to program more AT89S chips, I should probably get a
AT89ISP cable, since it is a bit more compact than the big SDK500
board. On the other hand, the machine I&amp;#39;m writing this on may
probably be the last machine I&amp;#39;ll have with a parallel port.&lt;/p&gt;

Oh, and if you google &amp;quot;atmel isp cable&amp;quot; the second result is the
document you wanted from the atmel site.&lt;/p&gt;

Sorry for hijack, but I have asked before about this elusive $25
programming cable without getting any answer.&lt;/p&gt;

&lt;p&gt;
I see many references to that $25 cable, but have failed to locate
it.&lt;/p&gt;

&lt;p&gt;
I have contacted Atmel support and they have failed to supply info
about how to build one and they can&amp;#39;t sell me one or point me to
anyone who sells them. Instead, they recommend that I invert the
reset signal and uses a STK500 starter kit as adapter.&lt;/p&gt;

&lt;p&gt;
Once upon a time, there has been a document on the Atmel site with
the description of this elusive cable. I can still find many posts
mentioning this description and specifying the - now defunct -
link.&lt;/p&gt;

&lt;p&gt;
Anyone who can help out?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: programmer circuits</title><link>https://community.arm.com/thread/101074?ContentTypeID=1</link><pubDate>Wed, 17 Sep 2008 04:04:05 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:002e083d-5ad3-44d6-8b5e-c9b107228a40</guid><dc:creator>erik  malund</dc:creator><description>&lt;p&gt;&lt;p&gt;
FLIP from Atmel is the &amp;quot;standard&amp;quot; Atmel programming software for
Atmel SPI programmable chips. it works with (If you insist, a
miserable copy of) the $25 Atmel &amp;quot;cable&amp;quot;.&lt;/p&gt;

&lt;p&gt;
Erik&lt;/p&gt;

&lt;p&gt;
PS 89&lt;b&gt;C&lt;/b&gt;51 is that even ISP programmable? the 89&lt;b&gt;S&lt;/b&gt;51
is.&lt;/p&gt;

i have atmel 89c51 microcontroller , and other things like max 232
, pc , cro, reg, cap.. every thing but i am not able to built my own
home made programmer. even i got a circuit from EFY book, still it
requires a pre programmer controller to program other which i dont
have&lt;br /&gt;
can any one help with this&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: programmer circuits</title><link>https://community.arm.com/thread/52423?ContentTypeID=1</link><pubDate>Thu, 11 Sep 2008 05:59:33 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:8c4e8b46-b663-4d61-b3ee-d8576724beac</guid><dc:creator>erik  malund</dc:creator><description>&lt;p&gt;&lt;p&gt;
the most popular post in fora dealing with such is &amp;quot;why can I not
get my homemade programmer to work&amp;quot; and, usually, they end up with &amp;quot;I
give up and will buy one&amp;quot; or &amp;quot;I will change to a UART programmable
chip&amp;quot;.&lt;br /&gt;
anyhow&lt;br /&gt;
&lt;i&gt;i have 89c51 ... is any possiblety to built my own programmer.
please help me&lt;/i&gt;&lt;br /&gt;
NOBODY can help you if you do not give the EXACT type and
manufacturer of the chip, there is absolutotally no such thing as
&amp;quot;generic programming&amp;quot; of &amp;#39;51s&lt;/p&gt;
