MEMS (sensors)

Hello, In the hardware manual of Teseo LIV3F, page 16, figure 11 it appears an inductance and a capacitor to put between VCC_RF and RF_IN. what are the optimal values for those passive components?. Thanks. Regards, A.

Is there any description / initialisation sequence to get the master I2C of the ISM330DLC running (Mode2)?

I assembled the ISM330DLC on an PCBA together with an IIS2MDC in Mode 2 -> ISM330 connected to an MCU by 4-wire SPI / IIS2MDC connected to the I2C interface od the ISM330 / DRDY of IIS2MDC connected to INT2 of ISM330

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?

USB Device HS-IN-FS does NOT work

I am using STM32Cube_FW_F4_V1.21.0.This is very excellent software.UART,SPI,I2S,RTC,,,work fine but HS-IN-FS.I have checked HS and FS works fine.My target board is STM32469I-EVAL board and I'm using EWARM compiler suite.My application is USB_Device/M...

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...

Datasheet with Registers for VL53L1X

Hi togetherI'm working on a project for my study. I want to program a VL53L1X sensor. And I want to do it with I2C and setting different Register. But I can’t find a datasheet with all the registers.Can someone help me?
