VL53L0X SPAD setup

I see in the documents for the VL53L1X the SPAD grid is labeled out. Is this the same grid labeling for the L0X? How does this grid work? For instance, does it grow as the cone does with further measurements? Thanks

VL53L0X: Cone at Distance X - Objects in way

Posted on May 26, 2018 at 15:52My question is about the VL53L0X.In the Datasheet on Page 30, there is a Collector Exclusion and Emiter Exclusion Zone defined. Sadly I did not find any information how big the cone will be at a Distance X. Is this con...

I can not set the Gyro LSM6DS3 to power save mode. Consumption is high

We have a circuit with STM32L433 and we connect it to ST Gyro sensor LSM6DS3.We work with the Gyro in normal mode just fine with i2c interface.on power up, the Gyro is configured as follow: // register address, register value 0x19, 0x38, 0x10...

Is there any ready made Wireless sensor node enabled with PIR or IR sensor to design wireless sensor network to track human or robot.

Example acceleration data - LIS3DH

Section 4.2.3 of the application note for the LIS3DH sensor provides example register values for various sensor readings. For +/-2g at high resolution mode the typical sensitivity is 1mg/unit. When BLE=0, I see why registers 28h and 29h are E0h and 1...

Solder-Bridge configurations for 4-microphone acquisition on the CCA02M1 module.

Hello, I am using an Nucleo - F401RE MCU, with the CCA02M1 module, and the STEVAL-MKI155V1 microphone coupon board and have encountered an issue with acquiring 4 audio channels. Using the Acoustic Source Localisation program provided in the X-cube-ME...

LIS3DSH Pedometer State Machine

Hi,We are trying to develop a pedometer based on LIS3DSH. We already have aSTM32F4 (F407) discovery board equipped with LIS3DSH. As stated in the document"Application Guidelines for LIS3DSH State Machine", there is anapplication "Pedometer Based on S...

New eval board and sensor requires update, can't file file to update

I just purchased a STEVAL-MKI019V3 evaluation board and a STEVAL-MKI183V1 LPS-33HW sensor board. I installed Unico 7.0.0. I received the error message "Error: The device selected is not supported by the motherboard" ... use DfuSe Demonstration softwa...

LPS25HB reading of temperature registers

Hello;I now test the LPS25HB pressure sensor with abnormal temperature reading. The actual ambient temperature is 30 degrees, but the read-out data TEMP_OUT_H (2CH) = DAH, TEMP_OUT_L = 50H. Slowly changing the ambient temperature, temperature reading...
