Battery life STEVAL-STLKT01V1 SensorTile
Posted on April 04, 2018 at 12:09Hi, I have the sensortile development kit, I wanted to test the battery life without soldering the sensortile to the cradle board, without using USB charge and with the accelerometer always active. Does anyone who ha...
VL6180X ECE threshold calculation
Posted on April 10, 2018 at 20:41Trying to figure out how to apply the Early Convergence Estimate value for the VL6180X proximity sensor.Design Tip DT0034 gives some information, but also populates the equations with some apparent magic numbers, and...
LSM303AGR with switchend GND
Posted on March 29, 2018 at 13:03Hi thereI'm developing an ultra-low-power minituarized system witch includes the LSM303AGR. since the power comes only from a small battery, the sleep-current of the LSM303AGR is too high, therefore we want to power ...
The LIS3DH crash test reads an abnormal acceleration value
Posted on April 10, 2018 at 04:14 When I was doing impact testing, using the 16g range, with my device gently knock on the desktop, the acceleration values read have acceleration values of more than 10g, a bit unbelievable, acceleration reading ...
Using lis3dx to detect the acceleration threshold in a car accident
Posted on March 23, 2018 at 07:53The purpose is to detect the car accident while ignore the normal acceleration variance during car driving. I know there is a high pass filter in the lis3dx sensor, and the cut-off frequency can be changed by setting...
Resolved! Questions about the interrupt config for Lis3dx
Posted on April 08, 2018 at 08:261) CTRL_REG3 (22h)Can I set both I1_IA1 and I1_IA2? 2) What is I1_321DA? 3) Our project uses two threshold, one for stronger force (e.g. collision), the other for weaker force (e.g. impact). I assume I should set INT...
[LIS3DH] In High-resolution mode (12-bit data output), why the BW is ODR/9
Posted on April 03, 2018 at 09:47In Low-power mode and Normal mode, the BW is equal to ODR/2 which is understandable. But in HR mode, the BW is ODR/9, why?
Resolved! Can't get IG2 work on either INT1 or INT2 for Lis3de
Posted on April 08, 2018 at 13:13I encountered a problem that IG2 doesn't get detected on either INT1 or INT2 pin. I confirm the IG1 work on both INT1 and INT2. Followings are the combinations I tried (CTRL REG1,2,4,5 kept unchanged):The INTx_CFG,IN...
