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 ...
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 ...
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...
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...
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?
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...
Posted on April 08, 2018 at 18:01Has anyone developed STM32 code for the AIS1120SX accelerometer?-Bruce#accelerometer-ais1120sx*
Posted on October 16, 2017 at 14:15Hello,I am trying to log accelerations above 2g. To do so I parametrized the LIS3DH as following:- CTRL_REG0: 0x10- CTRL_REG1: 0x57 (100Hz + Xen + Yen + Zen)- CTRL_REG2: 0x00- CTRL_REG3: 0x40 (IA1 on INT1)- CTRL_RE...
Posted on April 08, 2018 at 07:55I am using the LIS3MDL sensor for vehicle monitoring on parking spaces. When testing, I discovered that hysteresis occurs when the magnetic field on the sensor changes by more than a certain amount. When I recover th...
Posted on April 02, 2018 at 21:07Hi!I had a previous post asking how to interpret the values being drawn from the chips registers and I was able to get that working. (https://community.st.com/0D50X00009XkWYOSA3 )However, it only works as a 360 degre...
