I'd like to use MotionFX library on STM32H7 together with FreeRTOS and STemWin Middlewares. I noticed that MotionFX has been compiled with -mfloat-abi=softfp, but others are prepared for -mfloat-abi=hard.Could you please prepare "hard" ABI version o...
I have 2 LSM303C. Measurements show that the cooordinate system of the device is left-hand, but the "Figure 2. Pin connections" in the datasheet shows right-hand system (X-axis has an opposite direction). May be I do somethig wrong?
Dear ST,As I tested with, the LSM6DS drifted follow temperature. As you can image bellow, red line is temperature and green is degree (was calculated from X, Y, Z )I'd like to confirm LSM6DS had internal temperature compensation? If NO, how to do it?...
I noticed wrong values for heading when using 9x fusion library. When placing board flat on the table, then tilt and move it and replace it to the exact same position as before, the heading value differs by up to 90 degree. There seems to be an issue...
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...
In the application notes it is stated that:"The sensitivity of the magnetic sensor changes when the temperature changes. A temperature compensation digital block is introduced to compensate for the effect of temperature."Does this temperature compens...
Hello dear st engineerFor 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...
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 ...
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...
