I use LSM9DS1 with STM32L433 and get strange data.

I use LSM9DS1 with STM32L433 and get strange data.Initialization code:HAL_GPIO_WritePin(CS_A_G_GPIO_Port, CS_A_G_Pin, GPIO_PIN_RESET);   address = CTRL_REG4;   data = 0x38; //0b00111000   HAL_SPI_Transmit(&hspi1, &address, sizeof(address), 0x1000)...

VL53L1X reflectance targets?

Prior to the forums being migrated, I saw a post linking to sites to obtain reflectance targets for calibrating and testing the VL53L1X or VL53L0X. I.e. Grey 17% N4.74, Grey 54%, and White 88% N9.5. I'm moving from breadboard development with the sat...

How do I get the FP-NET-BLESTAR sample code to start sending all sensor data (acc, gyr and mag) from the STEVAL-STLCS01V1 sensor tiles?

It appears that the functionality is written into the code but I can't figure out how to get it to work. I am using the SW4STM32 IDE to build and compile and I know that in main.h there is #define ENABLE_MEMS 0 which can be changed to a 1 but the .h ...

Sparse LIS331 Datasheet(s)

Posted on July 12, 2018 at 08:16Dear all - especially STM developers,I recently integrated an LIS331HH sensor. It seams to be very nice sensor! But anyway while reading LIS331 Datasheet, I found that information required for proper MCU driver implem...

VL53L0x API data access inconsistency

The VL53L0X API (https://my.st.com/content/my_st_com/en/products/embedded-software/proximity-sensors-software/stsw-img005.license=1533144599665.html) requires definition of a platform-dependent structure of type VL53L0X_DevData_t. This structure must...

Using VL53L1X to detect ping pong balls on a table tennis board.

Hi all,I am designing an application which would tell me, if a ping pong ball lands on a particular area of a table or not. Below is a sketch that illustrates:Sensors would be placed on left side of the table, facing the other side as shown in the ab...
