MEMS (sensors)

I don't found config register for low pass filter between sensors and adc, it is not an issue the aliasing?

6-point Calibration of Magnetometer

I am trying to calibrate a magnetometer using the 6-point tumble calibration described here: https://www.st.com/resource/en/design_tip/dm00253745-6point-tumble-sensor-calibration-stmicroelectronics.pdfI am getting confused when that method is applied...

stm32f4 + lsm9ds1 + motionFx The output data looks like random，i need help thankyou

Hello dear st engineer​​For example, the yaw angle is random，and if (mag_cal_test.cal_quality == MFX_MAGCALGOOD) is always MFX_MAGCALUNKNOWNthis is my code ,​void example_main_lsm9ds1(void) { /* Initialize platform specific hardware */ platform_in...

steval-mksbox 1v1 BLE conenectivity range

I am using a steval-mksbox 1v1 and a rpi 3 to connect to it via ble usising the SDK. When I run one of the examples to connect, it detects the sensor during the scan, but when trys to connect "Unexpected error ocured". This happens when the distance ...

BlueNRG-MS framing error

I am having issues interfacing with the B-L475E-IOT01A's on-board SPBTLE-RF bluetooth chip. I am able to send header packets inquiring about the the bluetooth chip's write and read buffers. I have confirmed that I am doing this correctly, because I g...

MCU entry hardfault when I called the fuction of MotionFX_CM0P_initialize(), the sensor is LSM6DS3,

Hello bro, MCU entry hardfault when I called the fuction of MotionFX_CM0P_initialize(), the sensor is LSM6DS3,  the algorithm I am using is motionFX Library. The stack did not overflow. Do you have any good idea for this problem ? thanks!

How to compensate for asymmetric sensor array response?

I have an array of three VL53L0X sensors, mounted at -20, 0 and +20 degrees with respect to each other. The idea is to use the differential between the distances measured by the three sensors to determine the orientation of my autonomous wall-follow...
