How to set up LSM303AGR for accelerometer measurements?
The register CTRL_REG1_A is set with 0x57 and CTRL_REG4_A with 0x80.All output Accelerometer registers give the same value 0xC0.What is missing for correct accelerometer measurements?

LIS3DH Power-Down Mode
On my custom board LIS3DH is supplied with Vdd = Vdd_IO = 3.3 V and is driven through I2C digital interface.On power-on LIS3DH, after its boot sequence (5 ms) should be automatically configured in power-down mode with a current consumption less then ...
Range setting in ISM330DLC
Hi All,I am working on a project that is using ISM330DLC sensor for measuring the acceleration along the X,Y and Z-axis. When I set range 2G,4G and 8G I'm seeing difference in the sensor raw value and when I set it to 16G, I'm getting same data as 8G...
LSM6DSl edge-sensitive trigger mode
Hello,I want to use edge-sensitive trigger mode to synchronize multiple sensors. In the code snippet you can see the relevant code for that. The FIFO buffer doesn't get filled, even though I have a PWM as trigger on the INT2 pin. The low-pass filter ...
Can ST guarantee LIS2DH12TR never locks up
Hello,We are developing a product that has some circuitry permanently powered inside a sealed enclosure.We need to determine if we need a load switch for the host processor to cycle power to the LIS2DH12TR MEMs chip in the event that the MEMs chip lo...

LSM6DSL: Interrupts aren't latched when the LIR Bit is set to 1
Hello,Even though I have set the LIR bit to 1, the interrupts aren't latched. In the picture you can clearly see that the interrupt is reset before reading the route register of interrupt 1. The LIR bit is definitely set to 1. I have checked this wit...
