LIS2DU12TR accelerometer
Hi.
I used LIS2DU12TR accelerometer IC on the PCB.
It's angle value was changing every sec. but my smart phone app indicated current angle is 0.0 degree.
current angle is -0.515648
[proc_bt_read_all] TX data (len=15)
00 00 02 00 00 00 00 00 00 7F 00 64 37 01 00
current angle is -0.865430
[proc_bt_read_all] TX data (len=15)
00 00 02 00 00 00 00 00 00 7F 00 64 37 01 00
current angle is -0.460660
[proc_bt_read_all] TX data (len=15)
00 00 02 00 00 00 00 00 00 7F 00 64 37 01 00
current angle is -0.688205

---------------------------------
How can I set ODR and FS variables , more accuracy and more stable this IC ,
