We will use a Raspberry Pi connected to the TF Mini+ Lidar from Benewake. At the end post of this you&rsquo;ll be able to see a Realtime Graph of Lidar measurements. Each measurement is in centimeters and has an associated strength reading.</p> <h1 id="end-result">End Result</h1> <p>Here is what the graph looks like on a browser. There is both a distance and strength measurement on a plot. On the y-axis for distance we have a measurement in centimeters. The signal strength is the second graph. The strength is a 16-bit value.</p>https://lloydroc.github.io/post/hardware/tf-mini-lidar-unix-agent/Mon, 12 Oct 2020 00:00:00 +0000https://lloydroc.github.io/post/hardware/tf-mini-lidar-unix-agent/<h1 id="hahahugoshortcode71s0hbhb">TF Mini Plus Unix Agent for the Raspberry Pi</h1> <p>In this post we will create a Unix agent for the TF Mini+ LiDAR Range Finder. We&rsquo;ll run the agent on a Raspberry Pi B+ as a daemon. This agent will send out UDP datagrams with each LiDAR Reading. Also, we can use the <code>tfmini</code> program as a command line tool to read from the LiDAR and change the configuration. Overall, I&rsquo;ve noticed the TF Mini+ is quite accurate and snappy.</p>
