3 Ultrasonic Sensor to Raspberry Pi Straightforward connection | Quick Recap

The article discusses issues encountered with capturing audio data using the PCM1808 connected to a Raspberry Pi via I2S and the `arecord` command, where the recorded data size is disproportionately large. It explores potential causes, such as settings discrepancies or hardware limitations, and seeks community input for troubleshooting. This case highlights challenges in integrating hardware components with Raspberry Pi projects.

I have a stock Pi 3B with all Raspbian updates. From various sources I ' ve tried to cobble together alsa recording from an inexpensive PCM1808 device at 8K 24 bit stereo. To do this, I ' ve used the pigpiod daemon to provide the SCK for the chip at 2048000 Hz (pigs hc 4 2048000). The 3 outputs from the chip in master mode BCK, LRC and DOUT are connected to BCM 18, 19, and 20 respectively. All clocks look good and at the correct frequency. I noticed that the clock waveforms were low until I forced BCM 18 &amp; 19 to inputs from their state of ALT0. I enabled dtparam-is2-on in /boot/config. Txt. I used the instructions from adafruit to create the device in Linux. It worked, inasmuch as the device was created and reported by arecord -l. I can ' t say I know exactly what it is doing but everything I did understand looks OK to me. I used arecord -c2 -f s32_le -r8000 -d10 -M test. Wav to try to capture some data. It executed in well under a second. Nothing was connected to the audio inputs so I expected noise at minus 60-70dB or so. The file size, as expected, 640044 bytes, which is consistent with 10 seconds of stereo 32 bit floats at 8kHz. The problem is, of course, that it should take 10 seconds to capture this many samples. Using the time command I measured the actual capture rate at 1153x nominal. For instance, specifying 1000 seconds using -d1000 executes in around. 93 -. 94 seconds. Unsurprisingly it sometimes produces overruns. Changing the clock speed to 8192000 actually increases the run time to just over 1 second. I tried using the -t 0 flag in pigpiod as I ' d read in this forum that it might otherwise interfere with i2s without any change in behaviour. It seems to me that the breakout board is innocent in that if it provides a reasonable clock signal arecord should capture in real time. Random suggestions welcome! I do want to stick with this cheap interface, however, as I ' d like to build at least 20 in this configuration. Chris

This article explains how to access content and JavaScript variables within an iframe using Puppeteer, a Node.js library designed to control headless browsers. It provides a step-by-step guide on obtaining and manipulating iframe data, which is useful for web scraping and automated testing purposes. Readers will gain insights into leveraging Puppeteer’s capabilities for efficient data handling and automation.

Following on from the previous post about logging in and saving cookies with Puppeteer [https: //www. Mikestreety. Co. Uk/blog/login-with-puppeteer-and-re-use-cookies-for-another-window/], I also needed to access content and, more specifically, a JavaScript variable present within the iframe itself from within Puppeteer as this contained information I was hunting down. A working example of this code can be found in this git repository [https: //github. Com/liquidlight/puppeteer-typo3-translations]. In this example, we will be loading Wikipedia [https: //www. Wikipedia. Org/] with an iframe tester [https: //iframetester. Com/? Url=https: //www. Wikipedia. Org/]. Wikipedia has a rtlLangs variable available on the page which we will be accessing WHAT IS PUPPETEER? Puppeteer [https: //pptr. Dev/] is a Node/NPM package which allows you to create & control a headless Chrome instance, allowing you to do front-end/UI based tasks programmatically. It is hugely powerful and worth investigating if that is your thing. One of the most common examples is opening a page and taking a screenshot or submitting a form for testing. SETUP For this we are going to be working in a single JavaScript file - make a new one called iframe. Js in a fresh folder (or one where you are adding this functionality) INSTALL THE DEPENDENCIES The only dependency we need for this is puppeteer. Npm i puppeteer --save SET UP THE SCRIPT Inside your iframe. Js add the following skeleton Puppeteer code const puppeteer = require( ' puppeteer ' ); // Our main function const run = async () => { // Create a new puppeteer browser const browser = await puppeteer. Launch({ // Change to `false` if you want to open the window headless: ' new ' , }); // Create a new page in the browser const page = await browser. NewPage(); // Close the browser once you have finished browser. Close(); } // Run it all run(); Once saved, you can run the following to start your script node iframe. Js FIND YOUR IFRAME Once you have your code set up and running, the next step is to load (goto) the page with the iframe and locate it in the source. The location can be either via an ID or a HTML selector. Note: When selecting your iframe, be careful of who has control over the HTML and consider if the structure could change or if more than one iframe could appear on the page. Have a look at the docs [https: //pptr. Dev/guides/query-selectors] about what kind of selectors you can use. Const puppeteer = require( ' puppeteer ' ); const run = async () => { // Create a new puppeteer browser const browser = await puppeteer. Launch({ // Change to `false` if you want to open the window headless: ' new ' , }); // Create a new page in the browser const page = await browser. NewPage(); // Go to the page and wait for everything to load - this ensures the iframe has loaded await page. Goto( ' https: //iframetester. Com/? Url=https: //www. Wikipedia. Org/ ' , { waitUntil: [ ' domcontentloaded ' , ' networkidle2 ' ], timeout: 0 }); + // Get the iframe + const elementHandle = await page. $( ' #iframe-window ' ); + + // Get the `src` property to verify we have the iframe + const src = await (await elementHandle. GetProperty( ' src ' )). JsonValue(); + + // Output the src + console. Log(src); // Close the browser once you have finished browser. Close(); }; run(); ACCESS THE IFRAME CONTENT & VARIABLES With our iframe loaded and verified, we can now access the content on the iframe. This can be done with the contentFrame() function on our iframe variable. Const frame = await elementHandle. ContentFrame(); Once in our frame, we can run evaluate, which is a function which allows you to evaluate JavaScript [https: //pptr. Dev/guides/evaluate-javascript/] on the page (or in this instance, frame). The rtlLangs paramter is the name of the JavaScript variable on the page const rtlLangs = await frame. Evaluate( ' rtlLangs ' ); With that, the final code looks like: const puppeteer = require( ' puppeteer ' ); const run = async () => { // Create a new puppeteer browser const browser = await puppeteer. Launch({ // Change to `false` if you want to open the window headless: ' new ' , }); // Create a new page in the browser const page = await browser. NewPage(); // Go to the page and wait for everything to load - this ensures the iframe has loaded await page. Goto( ' https: //iframetester. Com/? Url=https: //www. Wikipedia. Org/ ' , { waitUntil: [ ' domcontentloaded ' , ' networkidle2 ' ], timeout: 0 }); // Get the iframe const elementHandle = await page. $( ' #iframe-window ' ); // Access the frame content of the selected iframe const frame = await elementHandle. ContentFrame(); // Evaluate JavaScript variable available and store the output const rtlLangs = await frame. Evaluate( ' rtlLangs ' ); // Log the output of the variable console. Log(rtlLangs); // Close the browser once you have finished browser. Close(); }; run(); Once we have access to the frame, we can load JavaScript variables, access the HTML or navigate as you would a normal page. Read time: 5 mins Tags: Node, NPM, Puppeteer
