David Laxer 2025-10-21T17:21:12Z https://community.wolfram.com/groups/-/m/t/3024384 I am very frustrated with the slow transfer of data from the Arduino serial COM port to the PlotLine[] in dynamic function. In the Arduino Plot Serial, data is drawn instantly. But when connected to WM with USB able, the plots are very very slow. About 10 and 20 to 1 speed. The Arduino code is sending a 6 pair of integers in ASCI format. Any suggestions as to how speed up. He Arduino sketch is this #include <Wire.h> #include "Adafruit_AS726x.h" //create the object Adafruit_AS726x ams; uint16_t sensorValues[AS726x_NUM_CHANNELS]; void setup() { Serial.begin(115200); while (!Serial) pinMode(LED_BUILTIN, OUTPUT); //inicia y permite la comunicacion con el sensor if (!ams.begin()) { Serial.println("could not connect to sensor! Please check your wiring."); while (1) ; } } void loop() { //temperature sensor //uint8_t temp = ams.readTemperature(); //ams.drvOn(); // descomentar esto si quieres usar el led del sensor para hacer medidas ams.startMeasurement(); //begin a measurement //permite que el sensor lea la data cuando este disponible bool rdy = false; while (!rdy) { delay(5); rdy = ams.dataReady(); } //ams.drvOff(); //descomentar esto si quieres usar el led del sensor para hacer medidas //lee los valores! ams.readRawValues(sensorValues); //ams.readCalibratedValues(calibratedValues); //Serial.print("{"); //Serial.print("Temp: "); //Serial.print(temp); //Serial.print(","); //Serial.print(" Violet: "); Serial.print(sensorValues[AS726x_VIOLET]); Serial.print(","); //Serial.print(" Blue: "); Serial.print(sensorValues[AS726x_BLUE]); Serial.print(","); //Serial.print(" Green: "); Serial.print(sensorValues[AS726x_GREEN]); Serial.print(","); //Serial.print(" Yellow: "); Serial.print(sensorValues[AS726x_YELLOW]); Serial.print(","); //Serial.print(" Orange: "); Serial.print(sensorValues[AS726x_ORANGE]); Serial.print(","); //Serial.print(" Red: "); Serial.print(sensorValues[AS726x_RED]); //Serial.print("}"); Serial.println(); ; } I have set up Baud speed to very high, but this makes no difference.

The gym python package has been installed, but when I try to execute env = DeviceOpen["OpenAIGym", "Atlantis-v0"] an error message in the Messages window appears saying that Python package cv2 is not installed. I have installed it as well using ResourceFunction["PythonPackageInstall"]["opencv-python"] Has anyone else gotten this device running on macOS. It seems also like the gym package is deprecated and further development happens in the package gymnasium. Thomas Gustafsson 2025-06-04T13:38:17Z https://community.wolfram.com/groups/-/m/t/3454636 Is it possible to make multichannel audio recordings (beyond stereo L/R) in Mathematica? I have a 4-channel audio interface ("Listen AudioConnect 4x4") attached but am only getting single channel results. Context: As a retirement project I am making a test system for loudspeakers in which I make simultaneous measurements of response at different sensors (sound pressure, voltage, current, displacement) to a stimulus generated in Mathematica and synchronously played back on the same audio interface. I have done this in the past prior to the introduction of Audio, but it required using a Matlab toolbox (and MatLink, no longer supported) for the data acquisition. In the new system I would like to do this entirely within Mathematica, but I can't seem to get enough input data channels to record. Daniel Warren 2025-05-03T19:31:15Z https://community.wolfram.com/groups/-/m/t/3365621 To run the Mathematica runtime directly on the PYNQ board, you’ll have to cross-compile Wolfram libraries for ARM. Wolfram Mathematica does not natively provide ARM-compatible libraries (libWolframRTL.so) for ARM platforms such as the PYNQ board. The libraries provided by Wolfram are typically built for x86-64 Linux systems, which causes the architecture mismatch when you try to use the ARM cross-compiler (arm-linux-gnueabihf-gcc). In this, ARM-compatible libraries from Wolfram are required. Or please provide a custom solution or suggest alternatives.

Please, what device do I need to use? Regards - Leo Leo Baumann 2024-10-30T18:03:29Z https://community.wolfram.com/groups/-/m/t/3294878 Hello, I am playing with Micro:bit and Mathematica. I wanted to simply visualize current temperature (measuring constantly) in Mathematica with temperature sensor on Micro:bit. I have programmed Micro:bit and wrote a code in Mathematica using Dynamic and ThermometherGauge function to do the visualization. It works, but I noticed that data showing in MakeCode is different (and more accurate) than the data showing in Mathematica. And I can be sure that the temperature showing in Mathematica is wrong because 32ºC is not possible currently and it never changes. And the gauge is constantly showing 10 then 50 and then 32ºC. I do not know why is that. Code for Micro:bit in JavaScript: let temp = 0 basic.forever(function () { }) basic.forever(function () { // Get the temperature in Celsius temp = input.temperature() // Write temperature to serial as a number serial.writeNumber(temp) // Write a newline to ensure proper reading serial.writeLine("") // Wait for 2 seconds before sending next value basic.pause(2000) }) Mathematica: Dynamic[temp = DeviceRead[microbit] ] Dynamic[ThermometerGauge[temp, {0, 50}, ScaleOrigin -> 0, GaugeLabels -> "Temperature (°C)"]] Thanks in advance! Ivo P. 2024-10-09T15:00:48Z https://community.wolfram.com/groups/-/m/t/3161083 My friend and I are both having the same problem. My microphone works fine in all other apps, except Mathematica can't detect any input devices. Has anyone found a solution to this? Windows 11 Pro. Permissions for the microphone are set correctly. I tried various devices. Yes, the drivers are up to date. Again, but me and my friend are having the same issue on separate computers.

I have a game controller, and in a notebook on my desktop some WL code. The controller sends a "button push" signal to the code just fine, captured by the code in the notebook with a line like this: Dynamic[ControllerState[2, "B4"]] However, I would like this to dynamically trigger a function in the code, similar to the way an event handler would work. To simplify things, let's just have it trigger `Beep[]` when the button is pushed. I could set a timer to repeatedly check the value of the ControllerState, but that can't be the best way to do it. The code is not part of a Manipulate or 3Dgraphics, but rather part of a custom interface. Can anyone please point me in the right direction? Thanks in advance. Mark Greenberg 2022-11-01T18:19:24Z https://community.wolfram.com/groups/-/m/t/2623336 Is there any possibility of using the ADALM-PLUTO with Mathematica? Analog Devices provides support for Matlab, but I wonder if it can be used in Mathematica as well. To complicate things more on macOS arm64. Codrut Popescu 2022-09-25T21:18:51Z https://community.wolfram.com/groups/-/m/t/1362109 I'm trying to use Mathematica to automate capture and analysis of USB camera images attached to a microscope. I believe the camera to be correctly installed because 1) The camera successfully captures images using the microscope's own software on my macbook pro through the USB directly to the camera and 2) the System Information >> Hardware >> USB >> USB2.0 Camera shows the camera recognized by the macbook pro's system setup. However, calls to FindDevices[] discover no camera but the iSight built-in camera. (I'm familiar with Mathematica's help files on this and related functions at http://reference.wolfram.com/language/ref/device/Camera.html). Any advice to make it discoverable? System Info: -- Mathematica 11 -- Computer: Macbook Pro -- OS 10.10.5 -- AmScope MU1400 USB Camera (connected to USB2.0 port on the macbook pro) Thanks, All.

Eric Goff 2022-02-08T20:29:34Z https://community.wolfram.com/groups/-/m/t/2313662 I installed OBS Studio on my iMac. It created a Virtual Camera which Mathematica recognizes as the primary camera. OBS Studio was installed for trying this application out but I don't have a need for it. There is no uninstall process, but according to online discussions, I just needed to delete the application in the /Applications directory, and its folder in the /Library/Application Support directory. I've done both, deleted the contents of Trash and rebooted. Running $ImagingDevices I get the output {"OBS Virtual Camera", "FaceTime HD Camera (Built-in)"} just as I had before deleting the OBS app and directory. When I execute CurrentImage[] The output is the OBS icon for the unconnected virtual camera. ![OBS Image][1] [1]: https://community.wolfram.com//c/portal/getImageAttachment?filename=obsimage.jpeg&userId=319259 Does anyone have a solution to this problem?

I am trying to follow this tutorial [Real-time data acquisition][1] I have an Arduino Yun Rev2 hooked up exactly as it is from the reference. Everything seems to be connecting and resulting as it should be until I reach... ![One red light and one green light][2] Which would indicate that I am missing something. I have the circuit hooked up exactly like the reference but Mathematica says "MicrocontrollerEmbedCode::nopen: Could not open /dev/tty.usbmodem1411." What does this mean and what can I try to remedy this? I am attempting to use this to model Simple Harmonic Motion with a spring mass system for a university presentation in April.

I am new to Wolfram Mathematica and connected devices, but I'm very familiar with Arduino. I want to read the same analog values that I read from my Arduino serial port, however when I ask Mathematica to read them, it gives me the voltage values. I'm hesitant to try and convert these voltage values as I already have an equation for converting ultrasonic sensor data over to change in distance of centimeters pertaining to a spring mass system. I know the circuit is working correctly, but the values that Mathematica reads are very different from the Arduino values. &[Wolfram Notebook][1] [1]: https://www.wolframcloud.com/obj/08015799-0c30-4d99-83c8-76cf88d5f7f1 Here's my arduino code: (I tried to post it in an ".ino " file but the file type wasn't supported) Jennifer Rittenhouse 2021-01-12T03:39:40Z https://community.wolfram.com/groups/-/m/t/2130901 I've been intending to interface Mathematica with the Raspberry Pi Camera, but it appears device handling in 12.1 is broken.

However, the next time I ran Mathematica and evaluated FindDevices[] I received an error "malloc(): invalid size (unsorted)" followed by a beep with an accompanying message that the kernel had aborted. Evaluating DeviceRead["RaspiCam"] resulted in the following error on the terminal /opt/Wolfram/WolframEngine/12.1/SystemFiles/Kernel/Binaries/Linux-ARM/WolframKernel: symbol lookup error: /opt/Wolfram/WolframEngine/12.1/SystemFiles/Components/RaspberryPiTools/LibraryResources/Linux-ARM/libRaspberryPiTools.so: undefined symbol: vc_vchi_dispmanx_init Evaluating the same on 12.0 results in the expected behaviour.
