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)...
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...
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 ...
I have confusion about I2C address for magnetometer.As in the datasheet at page 11:SDO_M: I2C least significant bit of the device address (SA0) for the magnetometerBut in the table 20 page 30:See picture enclosedIt looks like the SDO_M pin is used fo...
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...
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...
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...
When I use the breakout board included in the dev kit, the precision is at most 2 mm, but when I use the VL53L1X soldered on one of my board, the precision is really different. Is there a particular calibration or setting that are input to the breako...
Posted on July 16, 2018 at 08:55Hi,I am using ISM330DLC accelerometer and gyroscope sensor.I have initialized the accelerometer & Gyroscope register and reading the respective X,Y,Z register and that is providing huge noise in gyroscope values. And...
Posted on June 06, 2018 at 19:15GreetingsI am using the LIS2MDL to build a magnetic field sensor for the education market. When the magnetic field being measured exceeds the maximum allowed value, I notice that the LIS2MDL returns unpredictable dat...
