MEMS (sensors)

LIS3DH sensor is giving me huge offset when just resting on a table.

While flashing the LIS3DH I accidentally commented out a block of code causing read/writes of unintended registers. Below is the code which caused it. static void read_accel(void){ uint16_t MOSI = 0xA9; uint32_t MISO; int8_t dataRec; uint8_t i = 0; f...

My PC after updating the Windows can't detect the STMicroelectronics Port of my sensor!

I really need your help!It is happening something strange here!I have installed the "VCP_V1.3.1_Setup_x64" in the last two months to connect with my hardware. and my PC easily was detecting my sensor and everything was working very fine. But on 19th ...

Hi i have a bl475e-iot01a and is my first board. I want read the value of the sensor VL53L0X but i have no idea how to do it. Can someone help me? I use stm32cubeide and my only program for now is the tooglepin.

How can I select the right Accelerometer?

I am designing a sensor to measure vibration from industrial equipment. The main characteristics of the accelerometer are listed below:- Acceleration Range - up to 8g- Type - Digital- Output Type - I²C, SPI- Axis - X / Y / Z- Bandwidth - minimum of 1...

VL6180X defaulting to error 0x02 (VCSEL Watchdog Test ) after 60 seconds

I have the VL6180X doing continuous range measuring, which is working awesome, but after 60 seconds or so of the same reading I get an error in register 0x004D for VCSEL Watchdog Test. It says to replace the part, but I have had this with multiple S...

What is the proper way of implementing and handling status return values from the VL53L1X ultralight driver (STSW-IMG009)?

From Pololu's Arduino adaptation of the "heavy" driver =) (STSW-IMG007) I gather that the functions in vl53l1_platform.c should return 0 if they succeed and 1 if they fail, so that's what I've done in the ultralight driver. However, some of the other...

Errors compiling the demo project in Keil Microvision

I Unzipped the supplied demo software package and opened the tilebox project in Keil Microvision. After it autoinstalled all the support packages required I attempted to compile the code as per the readme.txt instruction. It failed due to not being a...

I would like to use the VL53L0Cx in my design. Is there a drawback to use it at 3.3V (instead of 2.8V as recommended) ? Also the spec is not clear about if the GPIO1 interrupt output is active low or high (I'm guessing active low...).

I2C communication issue with H3LIS331DL and/or LSM9DS1TR chips.

I’m trying to read 6 memory addresses I series. They represent appropriate X, Y, Z Accelerations levels. At low speed – up to 50kbps all good and working correctly. However if I increase I2C speed – up to 400 kbps, then I see wrong data being sent fr...

Need Help, can pay

Hi, I need help in SPI communication between an acclerometr and my board, Is there any how someone can do it for me, I will be willing to pay them or does STM supports any forums for help this way.Thanks
