Wirelings / Accelerometer: transfer the raw data to the real acceleration in m/^2

« on: March 13, 2023, 05:18:50 PM »

Hey Sir/Madam,

I have a simple question: what is the unit of acceleration in three axes and how can I transfer this value to the actual acceleration in m/s^2? I tried to figure it out but failed. I think transferring the raw data to the actual acceleration needs a scaling factor (like accelerometer ADXL345) but I don't know this specific factor for BMA250. Hope someone can help me figure it out.

Thanks!

I'm using the AST1001 accelerometer and the wireling Pi HAT. The Raspberry Pi I'm using is the same as yours and I installed the newest version of the OS. I just use a new SD card and downloaded the newest OS in it and run this OS on Raspberry Pi 3 v1.2 board.

Could you try following the steps in this link? https://stackoverflow.com/a/74147334

What is the value of 'revision' in the output of the first command?

Code: [Select]

cat /proc/cpuinfo
For me it is a22082

Hey,

Thanks for your reply but it seems I can use the accelerometer without connecting the Pi HAT. But I have a further question: what is the unit of acceleration in three axes and how can I transfer this value to the actual acceleration in m/s^2? I tried to figure it out but failed. I think transferring the raw data to the actual acceleration needs a scaling factor but I don't know this specific factor for BMA250.

Thanks!

I was able to get that example working fine on my Raspberry Pi 3 Model B V1.2.

Can you provide the following?

• Board name
• Board version
• OS name
• OS version

I'm using the AST1001 accelerometer and the wireling Pi HAT. The Raspberry Pi I'm using is the same as yours and I installed the newest version of the OS. I just use a new SD card and downloaded the newest OS in it and run this OS on Raspberry Pi 3 v1.2 board.

Wirelings / wireling Pi HAT config error

« on: February 24, 2023, 05:20:18 PM »

Hi all,

I'm using the Raspberry Pi to test the accelerometer and Pi HAT and I met a problem while following the tutorial provided by Tinycircuits. After installing all the packages mentioned in the tutorial, I run an example code and I got an error that said '"Adafruit-PlatformDetect version 3.40.3 was unable to identify the board and/or microcontroller running the Linux platform. Please be sure you have the latest packages running:'pip3 install --upgrade adafruit-blinka adafruit-platformdetect'". I run the command and it said the requirement was already satisfied. Could anyone please help me fix this error so that I can keep using the HAT and next the accelerometer? Thanks.

Best,
Yuntao
