關於G-sensor BMA422

[cody]

不好意思,小弟在這裡倒擾一下,因為我對G-sensor有興趣,最近在研究它們的工作原理這些相關資料..但我有些疑問,想請各位幫忙解答!

1.用在notbook上 使用兩顆G-sensor他們是如何算角度的呢
2. 我想要算出G-sensor的角度請問要怎麼算呢? 兩顆G-sensor的夾角,這或許能讓我有一些進步,並且能夠自己debug.

謝謝各位!

Hi cody,

Could we know the placement of two BMA422 on your notebook?
Do you mean you would like to calculate the angle at which the notebook opens?

Hi Robin,

Yes, one of my sensors is on the screen, and the other is on the motherboard.

Yes, I want to calculate the angles for sensor calibration by myself (maybe 86 ° or 240 ° or 289 ° …hese angles) I searched from google, it might have something to do with trigonometry, mechanics and vectors...

Thank your reply!

Hi Robin,

Could you have any idea? Or did I not express clearly?

Thanks!

Hi cody,

After internal check, we had this angle detection algorithm with two accelerometer, but it should be got under NDA. If you design a project with BMA422, you could contact with us and apply for it.
