multed<p>Я тут маялся с подключением к <a href="https://silverbay.space/tags/OrangePi5" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>OrangePi5</span></a> измеритель напряжения и силы тока <a href="https://silverbay.space/tags/ina219" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ina219</span></a> - но не сильно успешно. Но в руки мне попала <a href="https://silverbay.space/tags/RaspberryPi4" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>RaspberryPi4</span></a> и всё завелось без особых усилий.<br>Вот как так?</p>
cyclical_obsessive<p>Think I solved why my inside Docker (ROS 2) access to I2C INA219 current sensor was colliding with my outside Docker access to the device - forgot to map the /var/lock directory so the mutex is visible from both environments!</p><p><a href="https://fosstodon.org/tags/Docker" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Docker</span></a> <a href="https://fosstodon.org/tags/mutex" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>mutex</span></a> <a href="https://fosstodon.org/tags/ina219" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ina219</span></a> <a href="https://fosstodon.org/tags/robot" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>robot</span></a> <a href="https://fosstodon.org/tags/GoPiGo3" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>GoPiGo3</span></a> <a href="https://fosstodon.org/tags/ros2humble" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ros2humble</span></a></p>

cyclical_obsessive<p>Loving the INA219 Voltage and Current sensor. Allows my robot to monitor the Li-Ion battery recharging, and get off the dock when the charging current less is than 20mA. The robot is getting back on the dock when voltage shows there is about 15 minutes "playtime" left before the battery jerks the power off.</p><p><a href="https://fosstodon.org/tags/ina219" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ina219</span></a> <a href="https://fosstodon.org/tags/GoPiGo3" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>GoPiGo3</span></a> <a href="https://fosstodon.org/tags/robot" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>robot</span></a> <a href="https://fosstodon.org/tags/recharging" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>recharging</span></a> <a href="https://fosstodon.org/tags/liion" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>liion</span></a> <a href="https://fosstodon.org/tags/battery" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>battery</span></a></p>
Kaspars<p>It took 5 days for my Heltec Lora v3 <a href="https://mastodon.social/tags/meshtastic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>meshtastic</span></a> router node to use up 6.6Wh of one 18650 cell at 5% air utilization rate (one telemetry message per minute). That brings it to 6.6W / 5days /24h or 0.055W (15mA@3.7V) on average.</p><p>Importantly, this node was also powering a <a href="https://mastodon.social/tags/INA219" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>INA219</span></a> sensor which was doing the power measurements every minute.</p><p>Now I'll be doing a reference measurement without the INA219 and with zero telemetry.</p>
Kaspars<p>Has anyone been able to trigger or read <a href="https://mastodon.social/tags/INA219" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>INA219</span></a> using <a href="https://mastodon.social/tags/esp32" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>esp32</span></a> ULP coprocessor during sleep?</p>
Kaspars<p>The Heltec <a href="https://mastodon.social/tags/ESP32" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ESP32</span></a> Lora v3 uses <a href="https://mastodon.social/tags/TP4054" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>TP4054</span></a> with 2K PROG resistor so it only supports 0.5A charge current which would give roughly 2W max. This is why I'm planning on connecting ESP32 to the 5V output of solar FP6276B and let it buck-convert to 3.3V via CE6260B33M.</p><p>I'm wondering if it would be possible to somehow measure the charge current and report that via the Lora node? Is <a href="https://mastodon.social/tags/INA219" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>INA219</span></a> the only option?</p>
