<span style="font-size:14.0pt;mso-bidi-font-size:12.0pt">Hello
everyone, </span><br>
<span style="font-size:14.0pt;mso-bidi-font-size:12.0pt"></span>
<p class="MsoBodyText"><span
style="font-size:14.0pt;mso-bidi-font-size:12.0pt">
An evening, hosted by Spencer using Google Meet, via Spencer’s
account. Thank
you for helping out Spencer. There were around 18 participants
during the
evening. <br>
</span></p>
<p class="MsoBodyText"><span
style="font-size:14.0pt;mso-bidi-font-size:12.0pt">A few
teething problems as (just about) everyone poked around at this
new
communications medium, and associated user interface. <br>
<br>
Obviously no funds collected, but BR05 exec copied on this
report just for
information. <br>
<br>
This was a very interesting, and successful evening. Robin and
Bevin were brave
enough to share screens with the group, which turned out quite
well. <br>
</span></p>
<p class="MsoBodyText"><span
style="font-size:14.0pt;mso-bidi-font-size:12.0pt">I had to
leave the meeting at 9pm. If anyone has any notes on discussions
past this time, please post them via our email-reflector.<br>

<p class="MsoNormal"><span
style="font-size:14.0pt;mso-bidi-font-size:12.0pt">The
Evening was split into two halves with unprepared talks, and
demos starting and
6:30, followed by Robin and Bevin’s prepared talks starting at
7:30pm.</span></p>
<p><span style="font-size:14.0pt;mso-bidi-font-size:12.0pt">At
6:30pm, Stuart Brown started off the unprepared talks with a
demo of the
Universal Robotics UR3. This is a multi-axis unit with six
joints, and is
intended as being used as a configurable calibration fixture
associated with
some agricultural equipment.</span><span
style="font-size:14.0pt;mso-bidi-font-size:12.0pt"><br>
</span></p>
<p><span style="font-size:14.0pt;mso-bidi-font-size:12.0pt">Andrew
Errington talked about some commercial LoRaWAN products he had
been working
with. These units had been purchased from GoWireless in Rangiora
and included
the Ursalink UC1122 ~$100, Mikrotik LoRa 9 kit gateway ~$300,
and Teltonika
cellular modem ~$200. Everything appeared to be plug and play.</span></p>
<p class="MsoNormal"><span
style="font-size:14.0pt;mso-bidi-font-size:12.0pt">At
7:30pm, Robin Gilks setup a demonstration of an STM32
productivity build
environment based on the STM32CubeMX. The presentation started
off with some
history about his first weather station, and how it migrated
into a home-built
system using an ATmega328P, then onto the STM32F103C8T6 (the
blue-pill board).
Toolchain of choice for the STM32 were: compiler & tools <a
href="https://xpack.github.io/"><span style="mso-spacerun:
yes"> </span>https://xpack.github.io/arm-none-eabi-gcc/</a>,
debugger <a href="https://xpack.github.io/openocd/">https://xpack.github.io/openocd/</a>,
and the STM32CubeMX processor initial config generator from the
ST web site.
All of these tools are freely downloadable.</span></p>
<p class="MsoNormal"><span
style="font-size:14.0pt;mso-bidi-font-size:12.0pt">Bevin
gave us a brief update on his work with and open-source
ventilator project,
before moving on to his compiler talk. This months topics
included Macros,
Templates, and Inlining. This continues to be a fascinating
peak-under-the-hood
about computer language-translation. Thank you for all of your
work on this
Bevin.</span></p>
