MEMS and sensors

Posted on August 08, 2011 at 23:47Hi all.Sorry for the simple question, but I'm totally new to this but how can I write the sensor output to the SD card? I can't seem to find info on it in the documentation.My intention for using the board is for Data Logging #data-logging #sd-card

Posted on August 04, 2011 at 09:27HiCould anyone tell  how to align iNEMO V2 Board with 3D Cube (on monitor) to see the perfect rotation. ST provides a small 3D Cube demo, it's ok. I want to the in my VC++ program to accomplish the same alignment.1. Is there any command to do that ? 2. What the alignment do, i mean how it is done( any mathematical steps ?)    Is it like replacing the initial quaternion values of AHRS algorithm to the present     board quaterion output ? Thanks

Posted on July 28, 2011 at 12:35Hello, After downloading my software on the board, it only can executes when I am in debugging mode and make a RUN. When I restart the board without debug, my software isn't effective anymore, whereas it's supposed to still be loaded on the board. Do you have an explanation ? What can I do to really have an embedded application ? Best Regards Helene

Posted on July 09, 2011 at 10:44Hi,We have purchased the Inemo V2 board and are happy with all the functionalities it has to offer. The reason for buying the board was to evaluate ST's platform before using ST MEM's components in a commercial product.Currently our algorithm is being developed on the Inemo V2 board itself. Before proceeding deeper into this we would like to know certain points listed below.1. Is the Kalman Filtering library open source2. Is the AHRS library open source, wherein we can tweak something if desired or is a pre compiled library with only API calls provided.3. Can all the libraries and code implemented in Inemo which is available as open source be used in commercial product development. Are there any royalties or licensing issues we need to know about at the time of manufacturing.4. The commercial product involves upgrading firmware after b

Posted on July 18, 2011 at 05:16HiCan someone tell me how to get accelerometer data in ''g'' units.The data we get form iNEMO V2 is ''short int'' now which is output of ADC.In iNEMO Suit GUI, we can see the data in ''g'' units.How to get this, I mean formula in conversion ?Thanks 

Posted on July 13, 2011 at 06:40I have iNEMO V2 Board.  I want to use the inbuilt( embedded) filters of the geomagnetic module.How can i change the register settings of the Accelerometer ( LIS303DLH). I know there are two ways to do this ( iNEMO Suit GUI ,  Using the API)1. In iNEMO Suit GUI  if the AHRS Mode enabled ,Accelerometer parameter settings ( High-Pass Filter,ODR, reference), they are grayed out. Why is this ?2. My investigation reveals iNEMO V2 board can't give ''linear acceleration(without gravity or tilt)'', when the AHRS enabled. Is this true ?3. Now, I desperately need linear acceleration along with AHRS. If above 2 points are true. I really need help of ST to upgrade the firmware to provide linear acceleration, acceleration( linear acceleration+ gravity), along with AHRS.4. If i want to change accelerometer High-Pass Filter settings, and also want AHR

Posted on February 26, 2011 at 04:53 Hi Folks, I bought the iNEMO V2 evaluation board. It has the demostration firmware on it. I would like to use this board as a complete system since it has all the sensors on it. So, will I be able to install the Demo iNemo firmware once I erase the Flash. I am thinking it should be possible. Can I know how I can do this. I have a RLink and RIDE7 for the development purpose.

Posted on July 16, 2011 at 06:31Hi Fabio,( I could not find reply for my previous post by ST Fabio, so i posted the same here)I'm using Visual Studio 2008( sometimes MATLAB for testing).I need AHRS data along with ''linear acceleration''.1. Would you explain a way how to implement a High-pass Filter(HPF) which has the same response as embedded HPF of accelerometer ?2. Does this HPF completely removes tilt( gravity) to produce linear acceleration ?3. In LIS303DLH datasheet talks about ''linear acceleration''. Does this mean, it gives only ''linear acceleration(gravity removed)'' ?4. Would you give any mathematical steps how to remove tilt from the acceleration to get linear acceleration.Thanks.

Posted on July 14, 2011 at 07:08doas anyoane know, if the new ''iNemo-Engine'' is already available ? And if, where is it available?  Or when is it ? Which is the chip-configuration for this engine? LSM303DLM + L3G4200G ? #inemo-engine

Posted on May 26, 2011 at 12:21Hello, I'm trying to open iNEMO v2 firmware with IAR Embedded Workbench for ARM 6.20, but during building a houndreads of errors appears. Now I'm wondering if I use the proper tool for development of firmware. If anyone has any suggestions, I would be grateful for your response. Best regards Matesz

Posted on May 27, 2011 at 19:54I have questions regarding the configuration output data for the iNEMO board v2. Based on the iNEMO2_SDK.h header file, I know that the following output modes can be defined: - Default output mode - Raw output mode - AHRS output mode However, I have not been able to find the definition of these output modes in the iNEMO User Manual. I would appreciate it if someone could point me to the documentation where these output modes are defined. Thank you, David

Posted on July 13, 2011 at 11:16Can somebody tell me, what prebuild firmware is loaded in the two kit-parts in this specific demo? http://www.youtube.com/watch?v%3Dz3f4n9s3Kug The GUI seems to be EK302DL Thank's

Posted on July 06, 2011 at 16:33First I say Hello to all! Sorry for my english, it's not my native language. I wonder why iNEMO v2 uses two of ANALOG gyro if STm now has complete 3-axis digital solution (L3G4200D)? why its not used, what advantages Analog gyro over digital? Thanks for advice. Yuri.

Posted on May 18, 2011 at 07:48I'm trying to acces the FW Version & BufferUsage information of iNEMO .Please have a look at attached .cpp file (works for streaming data from iNEMO) .The BufferUsage function is very important for me since, I'm going to use iNEMO in Visual studio VC+ MFC environment. ( It would have been good if DLL generates a message & gives a single frame of data to application )I also would like to know, when program running if I Reset ( SW1) the iNEMO, I can see no data coming. How to know that the device has been Reset ?Thanks #inemo #visual-studio #inemo-sdk-visual-studio #sdk

Posted on May 25, 2011 at 03:45Hi friends,With deep interest and many trials, I could be able to connect iNEMO V1 to MATLAB. Your can see the attached INEMO_ConnectionV1.m working code. I commentedunloadlibrary('iNEMO_SDK')  which is making MATLAB unresponsive. I have to close the MATLAB and reopen again.I'm using MATLAB R2009a under Windows7Any ideas for this problem ?ThanksHarinath #inemo-v1-matlab

Posted on May 20, 2011 at 10:28Hello,I have problem with updating firmware in STEVAL-MKI062V2. According to manual to update it I have to switch board into DFU mode, but system doesn't see the device in this mode. Below I wrote out in few steps what I did. I checked it for both Windows 7(x64) and Windows XP SP3.1. Installation of whole software from CD: iNEMO Suit, DfuSe etc.2. Plug device via usb cable3. Check if it works correctly with iNEMO Suit. - It worked fine. I was able to capture some data.4. Try to go into DFU mode from iNEMO Suit option. - It displays a message that device has been switched into DFU mode, but programs ''STDFU Tester'' and ''DfuSe Demonstration'' seems to not see it. Moreover system Device Manager doesn't see it too.5. Turn off device. Hold button SW2. Turn on device. - System shows information about installation failure.If someone had similar prob

Posted on May 12, 2011 at 22:01Sorry about maybe stupid question, I am new in iNEMO and my question is about communication with other external microcontroller. Is it possible to use for example SPI protocol to communicate with iNEMO (internal firmware)? The reason to use such a iNEMO device is to build a self balancing robot. Thank you in advance for your help. walenw #inemo-faq

Posted on April 01, 2011 at 15:19Hello, I have just received the board but when trying to use it with inemo application, the values of x-y gyros are always very close to 0 (like 5 dps). All other sensors values seem correct, including z gyro. I tried to upgrade the firmware with latest version (2.2.0) but I still have the same problem. Does anybody have the same problem or some suggestions? Thanks for your help, Regards, Guillaume

Posted on March 17, 2011 at 20:47Hi everyone, I have an inemo v1 (STEVAL-MKI062V1) I DO NOT HAVE A V2 ! However, i don't have a jtag cable. Is there anyway i can upgrade the flash via usb/serial ? Thanks. #stm32-programming-burning-code #inemo

Posted on March 01, 2011 at 09:38Hi everybody, For LIS244AL accelerometer, I need to understand what does mean: sensitivity: 0.140*Vdd (V/g) So I need to understand what is the output voltage when the device is inclined by 1°. BTW, in which application should I use an accelerometer and in which one should I use a gyroscope.Herzlich,  MCU Lüfter

Posted on December 02, 2010 at 14:59Hello everyone,I've just purchased an evaluation board (iNemo STEVAL-MKI062V2) and I'm trying to run an application in Visual Studio 2010 Professional in C++. Here are my doubts:- As user guide I just found the pdf (Application Note AN3144) but I've realised that this is for the Version1 (STEVAL-MKI062V1). Is there any difference between V1 and V2?- Then, I've tried to use the help manual for version 1 and create a program. But I can't connect the board.in the line: iNEMO_Return = INEMO_SDK_ConnectFunction(''PL_001:COM12, BD115200'');the iNEMO_Return variable, returns me an 8 (which means CMD_TIMEOUT)Then, Visual studio says:iNEMO_SDK.dll', Cannot find or open the PDB filePL_001.dll', Cannot find or open the PDB file
