I bought openlog (ATMEL) SD Card reader/writers - and tried them using UART and SPI - but for some reason they do not work. Infact using 3.3 volt the micro does not even turn on.
Could you confirm which SD card reader/writer takes a 32G card and can overwrite the file FIFO. Thanks
What SD card readers are you currently using? Could you provide a few photos of how you have had them set up with your BLE 33 Sense for us? Most SD card breakouts should work fine with the Arduino if they are using SPI or UART (Which most SD modules are). Give us an idea of how you have it set up and if it is throwing any errors and we can hopefully get your project up and running as soon as possible.
Hi Blayden,
I asked for an SD car you sell that works with the arduino nano 33 ble sense.(I bought these ones I use with an ATMEL chip on board - and I do not want Core Electronics to waste time soting this one out. I would like to purchase a new SD card reader/writer that works on the Arduino nano 33 ble sense. Thanks
If you have a project with any audio, video, graphics, data logging, etc in it, you'll find that having a removable storage option is essential. Most microcontrollers have extremely limited built-in storage. For example, even the Arduino Mega chip...
Have you tried it out on the Nano 33 ble sense? What pins did you use for each of the SPI I/O requirements? Could you confirm that you have tried this out on a Nano 33 BLE sense?

Can someone confirm they have tried this out please? I am asking you to forget my efforts - I want to purchase something thats works urgently for a prokect and I want you to confirm that thixs works with the configuration you send me.
Thanks

I have also got advice from ChatGPT and BARD and code too -and they did not work out. This is why I am looking for support from the experts who sell the product because they know how to do it!
Please help.
Thanks
Hi James, Have you tried it? Can you confirm that Core Electronics has tried this out as a number of support staff promised to do. I would appreciate your advice and confirmation - I would like to order more nanos and SD card readers - because I have been helped immensely from ChatGPT and BARD and have built many solutions from a single unit
Hi Core Support Team,
I bought more than $700 worth of devices over the past few months and never asked for help - all systems I have deployed in my research at Macquarie University and at work at Technologycare are working and generating data.
All I want to do it put this data on SD card where sites will not give me access to their infrastructure.
So I would appreciate your help very much.
Thanks
Olly
This user found a SD card that worked with that configuration:
AMLResearchProject/all-arduino-nano-33-ble-sense-classifier GitHub
kwmobile 2 Mdulos de Tarjeta Micro SD para Arduino y Otros microcontroladores - Mdulo Lector microSD para Circuito Arduino Raspberry Pi : Amazon.es: Informtica
Since it is just an SPI connection the wiring is all standard and you only need to run the example code built into the Arduino IDE to get it to work.
You can find the example code used under Files > Examples > SD > Datalogger
The pin assignments are included as a comment at the top of the example, and the silkscreen on the bottom of the microSD card reader shows the function of each pin.
Below is a screenshot of the test we ran.

Since every language has its own pronunciation rules, the screen reader needs to know which language it should "speak." Web pages specify document language with a lang attribute on the tag, in order to encompass the entire document. The page you are reading right now uses , with "en" being the code for English. This also facilitates automatic translation of content.
In such cases, the lang attribute (in this case lang="fr") is typically applied to a tag surrounding the other-language content. This flags a temporary departure from the previously-specified document language.
Audio interfaces present content linearly to users, one item at a time. This contrasts with the way in which most people use visual interfaces. Sighted users can scan an entire screen almost instantaneously, comprehending the overall layout, the artistic style, and other macro-level aspects of the content. Screen reader users cannot comprehend these macro-level aspects as quickly. The linear progression through the content from beginning to end is somewhat like automated telephone menu systems which do not reveal all of the options at once. Users must progress through such systems in a step-wise manner. The insight that audio interfaces are linearized versions of web content is an important one that should guide web developers during the engineering and design process.
One way is to use the Tab key to jump from link to link. This gives the user an idea of where the page links to, and can be a useful way to run through the content if the user is looking for a specific link. A related technique is to obtain a list of the links on the page, arranged alphabetically. The drawback of these methods is that the user does not hear any of the non-link content, and may miss important information this way. See
Users can jump from paragraph to paragraph, listening to the first sentence or two before moving on to the next paragraph. This technique resembles the way visual users explore the page before focusing on an area of interest. Users can also jump from element to element, such as tags, links, form elements, list items, or other units of content.
Skip links at the top of the page allow users to bypass the main navigation and go directly to the main content. They speed up the reading process and help users distinguish between the main navigation and the main content.
Using any screen reader for the first time can be a confusing and discouraging experience. Using an audio interface is almost always a little disorienting for sighted users. Also, much of the content on a web page will seem to be inaccessible, when in fact the problem may be that the new user simply does not know how to use the screen reader.
Developers who are serious about wanting to know how their content sounds on screen readers will need to either work closely with people who use screen readers on a regular basis or else devote the time to learn how to use a screen reader effectively. However, testing accessibility with a screen reader is best conducted using the default or minimally customized settings and limited navigation techniques. This allows the basic accessibility of the page to be analyzed without relying on strategies employed by screen reader power users.
This is not yet another port of the great zxing library, butmore of an extension to it. This implementation features a barcode locator whichis capable of finding a barcode-like pattern in an image resulting in anestimated bounding box including the rotation. Simply speaking, this reader isinvariant to scale and rotation, whereas other libraries require the barcode tobe aligned with the viewport.
Quagga makes use of many modern Web-APIs which are not implemented by allbrowsers yet. There are two modes in which Quagga operates: 1. analyzing staticimages and 2. using a camera to decode the images from a live-stream. The latterrequires the presence of the MediaDevices API. You can track the compatibilityof the used Web-APIs for each mode:
This npm script builds a non optimized version quagga.js and a minifiedversion quagga.min.js and places both files in the dist folder.Additionally, a quagga.map source-map is placed alongside these files. Thisfile is only valid for the non-uglified version quagga.js because theminified version is altered after compression and does not align with the mapfile any more.
This method initializes the library for a given configuration config (seebelow) and invokes the callback(err) when Quagga has finished itsbootstrapping phase. The initialization process also requests for cameraaccess if real-time detection is configured. In case of an error, the errparameter is set and contains information about the cause. A potential causemay be the inputStream.type is set to LiveStream, but the browser doesnot support this API, or simply if the user denies the permission to use thecamera.
If you do not specify a target, QuaggaJS would look for an element that matchesthe CSS selector #interactive.viewport (for backwards compatibility).target can be a string (CSS selector matching one of your DOM node) or a DOMnode.
If the decoder is currently running, after calling stop() the decoder does notprocess any more images. Additionally, if a camera-stream was requested uponinitialization, this operation also disconnects the camera.
This method registers a callback(data) function that is called for each frameafter the processing is done. The data object contains detailed informationabout the success/failure of the operation. The output varies, depending whetherthe detection and/or decoding were successful or not.
Registers a callback(data) function which is triggered whenever a barcode-pattern has been located and decoded successfully. The passed data objectcontains information about the decoding process including the detected codewhich can be obtained by calling data.codeResult.code.
