Folks,<br>
I recently had a chip programming problem and when I debugged it
the issue was surprising: a defective OSH Park PCB. Here are the
details of the problem and the rapid response by the vendor.<br>
I needed more ICSP breakouts for solderless protoboards and went
looking for a cheap solution. By using the TriEmbed <a
href="http://triembed.org/searchoshpark.html">OSH Park shared
project search page</a> (a link in the <a
href="http://triembed.org/#resources">TriEmbed resources</a>) I
looked for "avr" and found shared project <a
href="http://oshpark.com/shared_projects/JCbaKwcL">"AVR ISP
adaptor"</a> submitted by nsayer. I ordered three of these to use
with 2x3 male headers and they arrived 14 days later.<br>
I was having problems programming chips so when I switched to a
breadboard using one of nsayer's adaptors it took a little extra
time to figure out why I couldn't get joy. I'll never forget staring
at a board that should look like the image at <a
href="http://triembed.org/images/avr-icsp-ok.jpg">http://triembed.org/images/avr-icsp-ok.jpg</a>
but instead I found my self searching for a missing trace. A portion
of the MOSI signal connectoin was simply missing as shown by <a
href="http://triembed.org/images/avr-icsp-ok.jpg">http://triembed.org/images/avr-icsp-over-etched.jpg</a><br>
OSH Park has a support system with a ticket submission system and
a few hours after sending the details an automatic order for three
more boards was initiated , so I'll get three good boards at no
charge. They thanked me for the well-doc'd bug report and that was
that. <br>
