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!

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
