+      <h2>Adventures with I²C</h2>
+      <i>26 January, 2019</i>
+      <p>I went to London last weekend to attend the Agorama Web Jam and had a super groovy time. Everyone was so friendly and welcoming. Felt great to be hanging with cypherhomies in proximal timespace, dreaming and growing brighter futures together. I got to meet and chat with @eb4890 about PeachCloud and gained a better understanding of their plans around dyndns with SSB integration. Stoked to see that developing! It was also really encouraging to hear different folx voicing the need / desire for plug-n-plug p2p devices; fuel for the inner fire. Big thanks to all involved.</p>
+      <p>TLDR: Real-Time Clock Module added to Pi / PeachCloud (I²C is working on Debian Buster ARM64)</p>
+      <p>I spent most of my week doing web design work on another project. Finally got that finished and deployed yesterday and decided some hardware hacking would be a nice change of pace. Adding a real-time clock (RTC) felt like an achievable goal - one which would allow me to lean a little further into basic electronics & hardware shenanigans. @mikey already had this on the ‘next steps’ list for PeachCloud:</p>
+      <blockquote>add Real-Time Clock to keep track of time (so you can be off-grid and still know the time)</blockquote>
+      <p>I received a DS1338 RTC module as a Christmas gift for this project (thanks Dad). The datasheet can be accessed <a href="http://www.hobbytronics.co.uk/datasheets/DS1338-RTC.pdf" title="DS1338-RTC Datasheet">here</a>. A note from the retailer’s website:</p>
+      <blockquote>A Real Time Clock Module with battery backup using the easy to use DS1338 chip. The DS1338 is functionally the same as the popular DS1307 chip with the difference being that the DS1338 works at any voltage from 3V to 5V making it easy to use on either 3.3V and 5V systems without modification or logic level conversion. Ideal for your project including Arduino and Raspberry Pi projects.</blockquote>
+      <p>I received my first lesson in soldering last week and attached pins to the RTC. That made it a simple process to plug the module into my breadboard and connect it to the Pi. The module works on I²C and only requires 4 connecting wires (power, ground, SDA, SCL). The I²C pins on the Pi include a fixed 1.8 kohms pull-up resistor to 3.3v, meaning that no additional resistors needed to be included in the wiring setup.</p>

+        <figcaption>DS1338 RTC module plugged-into a breadboard & connected to a Raspberry Pi.</figcaption>
+      </figure>
+      <p>Following the AdaFruit guide to <a href="https://learn.adafruit.com/adding-a-real-time-clock-to-raspberry-pi/set-up-and-test-i2c">Adding a Real Time Clock to Raspberry Pi</a> (with small additions), I was able to run an I²C scan and verify that the module was wired correctly to the Pi:</p>
+      <code>sudo apt-get install python-smbus i2c-tools</code><br>
+      <code>sudo modprobe i2c-dev</code><br>
+      <code>sudo i2cdetect -y 1</code><br>
+      <p>The final command in the sequence prints an array to the console, with 68 denoting the presence of the RTC module. This is a sign that the device is properly wired and connected. Great! This is where things started to get tricky…</p>
+      <p>If we were running Raspbian for this project the next steps would be pretty simple. As it turns out, the process for Debian Buster ARM64 is quite a bit more complicated. A <a href="https://code.overdrivenetworks.com/blog/2018/07/debian-buster-on-a-raspberry-pi-3-model-b-plus/">blog post</a> I found last night neatly summarizes the pros and cons of this choice:</p>

+        <img src="/computers/debian_pi_pros_cons.png" alt="List of advantages and disadvantages of running Debian Buster ARM64 on Raspberry Pi." style="width: 100%;" />
+        <figcaption>List of advantages and disadvantages of running Debian Buster ARM64 on Raspberry Pi.</figcaption>
+      </figure>
+      <p>No kidding! There were, however, a few crumbs along the way to sustain me over the course of the journey. These included <a href="https://raspberrypi.stackexchange.com/questions/41277/what-is-needed-to-get-i%c2%b2c-working-with-debian-jessie">What is needed to get I²C working with Debian Jessie?</a> and <a href="https://raspberrypi.stackexchange.com/questions/60084/i2c-transfer-failed-flooding-the-logs">"I2C transfer failed" flooding the logs.</a></p>
+      <p>I appended <code>dtoverlay=i2c-rtc,ds1307</code> and <code>dtparam=i2c_arm=on</code> to <code>/boot/firmware/config.txt</code> and <code>i2c-dev</code> to <code>/etc/modules</code> but the RTC device was still not coming under control of the kernel driver. When I looked at <code>/var/log/kern.log</code> I found an <code>i2c could not read clock-frequency property</code> error which led me to the second of the two posts linked in the paragraph above. It seemed I would need to decompile, patch and recompile the device tree blob for my Pi. I copied <code>/boot/firmware/bcm2837-rpi-3-b.dtb</code> from the Pi to my laptop for the following steps:</p>
+      <code>sudo apt-get install device-tree-compiler</code><br>
+      <code>cd /place/where/dtb/file/was/pasted</code><br>
+      <code>dtc -I dtb -O dts > bcm2837-rpi-3-b.dts</code><br>
+      <p>That gave me a human-readable decompiled device tree (dts). I then manually added <code>clock-frequency = <0x186a0>;</code> to the generated dts file (line 570 for me).</p>
+      <p>Recompiled the dts to binary blob format:</p>
+      <code>dtc -O dtb -o bcm2837-rpi-3-b.dtb bcm2837-rpi-3-b.dts</code>
+      <p>This left me with a patched dtb to replace the faulty dtb on the Pi. At this point I was thinking: ‘I don’t know what I’m doing but it feels pretty cool’. Once I’d patched the dtb and rebooted my Pi I no longer had clock-frequency errors in the kernel logs - a minor victory! Still, I couldn’t seem to get the RTC kernel driver to work. Eventually I returned to <a href="https://www.raspberrypi.org/forums/viewtopic.php?p=330617">Instructions to Configure DS1307 or DS1338 RTC</a> and had another go:</p>
+      <code>sudo modprobe i2c-bcm2835</code><br>
+      <code>sudo bash</code><br>
+      <code>echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device</code><br>
+      <code>exit</code><br>
+      <code>sudo modprobe rtc-ds1307</code>
+      <p>I ran <code>sudo i2cdetect -y 1</code> for the 234th time and bingo! It works! <i>Running around room celebrating.</i></p>
+      <figure>
+        <img src="/computers/i2c_working.jpeg" alt="Screenshot of terminal showing successful configuration of I²C RTC module." style="width: 100%;" />
+        <figcaption>Screenshot of terminal showing successful configuration of I²C RTC module.</figcaption>
+      </figure>
+      <p>This is really exciting because it opens the door to (relatively) easy integration of other I²C devices (sensors, LCD displays etc.). Next step will be to fine-tune the process so that everything loads correctly on boot. If you stuck with me this far - thanks for reading!</p>

       <p>So I think many of us have a basic understanding of what a lichen is: a symbiotic mutualism between a fungus and algae / cyanobacteria. The fungus provides a cosy home for the algae, along with water, nutrients and anchorage; while the algae photosynthesises and provides the fungus with carbohydrates. As Trevor Goward puts it: “Lichens are fungi that have discovered agriculture”. Put another way, lichen are fungi with solar panels. But I’ve only recently learned that the situation is far more complex than this simple 1:1 rendering of fungus and algae.</p>

       <p>This is likely <i>Aloe ferox</i>, though it should be said that I’m still learning to differentiate species. It’s categorised as a solitary, non-branching tree aloe. There is another one nearby which is easily 5-6 meters tall. Some species have yellow flowers, while others are orange, red or pink. They are wonderful neighbours.

       <p>Today I thought about ripeness. How do you know when it’s just right? Well, it’s different for every plant I guess. With blueberries I’m learning to evaluate ripeness based on sight (colour of berry) and touch (firmness when gently squeezed). When I first started picking them, just two weeks ago, I only used my eyes and thus tended to pick unripe, tangy berries. Now I get 'em when they’re oh-so-sweet! In the last few days I’ve also started to notice the rate at which the berries ripen and can time my future visits more precisely.</p>
       <p>The more time I spend with these plants, and the more patient I become, the more fully I come to appreciate their being. So this is then one way to form relationships (and sometimes friendships) with plants: visit them regularly, use all your senses to engage and be patient. I reckon the same approach might work with humyns ;)</p>

If you enjoy geeking out about plants, insects, chemistry or ecology, I highly recommend taking a listen!</p>
+      <p>Here’s a brief summary of the part which blew my mind. There are loads more juicy details in the podcast so I’m confident that I’m not spoiling it for you by sharing this.</p>
+      <p>There’s a plant (<i>Ceropegia sandersonii</i>) that releases chemical compounds which mimic those released by honey bees when they are wounded (e.g. by spiders). This suite of compounds attracts <i>Desmometopa</i> flies which specialise in stealing food from spiders (they consume the body fluids of the injured bees). The fly comes to the flower expecting a meal, becomes trapped and covered in pollen, and is released a day later when the flower withers - allowing it to visit more flowers.</p>
+      <p>How’s that for a pollination syndrome?! Isn’t that just ridiculous! Gettin’ me all fired up on science over here!</p>
+      <p>More info can be found on the <a href="https://en.wikipedia.org/wiki/Ceropegia_sandersonii">Wikipedia page for Ceropegia sandersonii</a> and in this article: <a href="http://www.the-scientist.com/?articles.view/articleNo/47214/title/To-Attract-Pollinators--Flower-Mimics-Wounded-Bee/#post143971">To Attract Pollinators, Flower Mimics Wounded Bee.</a></p>
+      <p>A friend of mine has a gorgeous vine growing as a potted plant at her house. Only while listening to this episode did I realise it’s a member of the Ceropegia! Now I’m stoked to identify it to species level and ask her ever-so-sweetly if I might take a cutting (or seeds). The one she has looks very much like this <i>C. linearis sub. woodii</i>:</p>
