steval-mki109d with steval-mki245KA standalone logging

Hello,

I was wondering if it is possible to set the steval-mki109d with steval-mki245KA to standalone.

I would like to test the ISM330BX what is happening when rotating. Thus I have set up a kit with a battery pack and I can start up the measurement with MEMS studio 2.0. When I just pull out the USB-C connector, I think everything will go on (LEDs keep doing the same thing as when i turned the mems on in MEMS studio). But when I reconnect to MEMS studio the ISM330BX will have to be configured again. Meaning I cannot check the final values after rotating.

Is there any way to for example log all the data to a SD card without writing all the code by myself? Or any other way to read out the final value without the processor/MEMS resetting?

Thanks!

Hi @Leo0n ,

On page 21 of this document there are instructions on how to decode the data sent by ProfiMEMS and on page 16 the list of supported commands.
After configuring the device, using the command *debug\r\n and then *start\r\n you will receive the samples in human readable format and if you want to implement the serial parser you should be able to do everything yourself.

Hi @Leo0n ,

If you connect the board via USB-C, every time you disconnect it you have to redo the configuration because you stop powering the board.
The functionality with SD Card will be added in future releases.

Hi Federica,

I have connected an external power source to the board, thus the processor keeps running when I disconnect the USB-C cable. 

What I have tried is to use a COM port monitor after the movement to get my results. But I could not find any information about the COM port settings and the data I receive then. Is there any information available about this?

I just need a few measurement after the wireless movement, which I can decode myself if necessary.
