Suprith-MSc Posted April 9, 2022 Share Posted April 9, 2022 Hello, I am facing a problem while using STEVAL-MKI197V1(https://www.st.com/en/evaluation-tools/steval-mki197v1.html) with Raspberry pi 2 and try to fetch the accelerometer values. I am not able to interface this with Raspberry pi 2. I am using python language for scripting. I am curious if they is anything to be done before interfacing (such as downloading the libraries compatible with Raspberry pi). Since I am new to this process, I would like to know what would be the best approach to interface this sensor and fetch the accelerometer values using python language in Raspberry pi. It would be of great help if anyone has any reference on this and is happy to share. Thanks Link to comment Share on other sites More sharing options...
JamesL Posted August 30, 2022 Share Posted August 30, 2022 Sorry, I don't know the answer, but, I see that you also posted your question here: https://forums.raspberrypi.com/viewtopic.php?t=333686 The rasberrypi forum is probably the best place to find the answer. Good luck. Link to comment Share on other sites More sharing options...
GlobalInnovator Posted March 10 Share Posted March 10 (edited) Hello @Suprith-MSc, I am trying to turn smartphone with accelerometer sensor into remote outdoor seismographic sensor. I plan to test API and wifi connectivity to access sensor data from server run on smartphone. But what matters I need to install audio-coupler to turn accelerometer data into audio signals output via audio jack in smartphone to be broadcasted via radio to remote RTL SDR server run on my PC to receive accelerometer sender data remotely at large distance, data from many ourdoor sensors in parallel and process inputs with Python scripts to generate live charts, 3D plots like this I develop Earthquake Prediction System for Turkey based on Precognition and input data from seismigraphic sensors, from remote seismographs and more Job is easy if you are an experienced developer, so I need to learn a lot to integrate: 1. accelerometer sensor in smartphone to output data via Audio coupler app 2. Input such audio signal into radio transmitter 3. Have RTL SDR radio to receive such signal 4. Have Python script to decode the signal 5. Have Python scripts to generate live 3D charts as above, FFT seismograms to calculate signal distribution delay underground and finally study if earthquake activity in the region accelerates to result in 5, 6, 7+ level earthquakes ( vide Turkey) https://earthquake.usgs.gov/earthquakes/map/?currentFeatureId=us7000jiph&extent=33.30299,31.92627&extent=40.56389,42.47314&range=month&magnitude=all&listOnlyShown=true&baseLayer=satellite wish you all the best darius Edited March 10 by GlobalInnovator Link to comment Share on other sites More sharing options...
GlobalInnovator Posted March 10 Share Posted March 10 follow-up My girlfriend just pointed me out to a nice research papers on Loma Priesta Earthquake analysis, on how the earthquake data can be extracted from seismograms and processed into 3D plots https://www.researchgate.net/figure/Simulations-of-the-Loma-Prieta-earthquake-using-an-energy-based-envelope-shape-Response_fig12_315724830 https://www.mathworks.com/help/matlab/matlab_prog/loma-prieta-earthquake.html Link to comment Share on other sites More sharing options...
