VL53L0X 1.8 I2C and XSHUT
We are running the sensor at 3V but the I2C is 1.8V. Does this mean the XSHUT is also 1.8V referenced. Does the XSHUT pull-up go to 3V or 1.8V?ThanksLeon

LSM6Ds3TR-C embedded temperature sensor accuracy
I would like to know what the accuracy of the embedded temperature sensor in LSM6DS3TR-C. However, I cannot find this information in the datasheet.
Resolved! Hi, I got the VL53L1X Satel board but I am not able to link the exact pin names to the pin numbers of the breakout board. Can anyone please assist me? Thanks in advance
reference : https://www.st.com/resource/en/data_brief/vl53l1x-satel.pdfAs you can see, I have the names of the pins from the data sheet but I don't know which is pin 1 or pin 2 and so on
Resolved! lis2mdl driver computes the wrong hard iron offsets
lis2mdl_reg.c has an error in the function int32_t lis2mdl_mag_user_offset_set(stmdev_ctx_t *ctx, int16_t *val).The function incorrectly calculates the OFFSET_X_REG_H, OFFSET_Y_REG_H, and the OFFSET_Z_REG_H registers because it converts val[0] to an ...

How can I choose gyro for BLDC position control?
Hi, I am working on high precision position control with BLDC motors on my master thesis. I am trying to control the position with an encoder on the TI-C200 processors and It's ok for now. The control accuracy is 0.1 degree on the encoder but for my ...
Resolved! Using STM32F446, ISM330DHCX and MotionFX, computed yaw angle is correct after a controlled 90-degree right rotation, but the yaw angle is off by ~3 degrees after each 90-degree left rotation. What could be causing this issue?
The MotionFX Library is initialized as follows: MotionFX_getKnobs(&iKnobs); /* Modify knobs settings */ // Configure knobs with non-default values iKnobs.output_type = MFX_ENGINE_OUTPUT_ENU; iKnobs.modx = 1; // No decimation iKnobs.ATime = 10; // ka...
