how to change mode to 8g on MMA8451Q?

[stefanpäßler]

Hello,

i´m using accelerometer MMA8451Q on LFSTBEB3110 sensor kit.

after testing i want to change the mode to 4g oder better 8g but i don´t know how.

i read that i have to use code warrior and change something in the registers but i have neither the knowledge nor the devices for connecting and programming the kit.

so my question is, do some options exist like switch a jumper or change settings in the toolbox?

thank you for helping

Hi Stefan,

Unfortunately no, the designers of the SW GUI for this kit didn’t added the function to change g range or the registers values, and it is not possible to do this change via Hardware, so, the only way to change it from 2g to 4g or 8g would be programming the board externally via Code Warrior.

If you do not have access to Code Warrior, and you need to check the full functionality of the Accelerometer MMA845x Family, then I would recommend you to get the LFSTBEB845X Evaluation kit compatible with Sensor Toolbox GUI: https://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=LFSTBEB845X

In the following User Guide, you can find all the windows and features available for this kit: http://cache.freescale.com/files/sensors/doc/user_guide/MMA845xQSTUG.pdf
