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 ...

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...

Resolved! LIS3DH outputting unexpected data

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...
