Hi. I am working on MP45DT02 microphone on STM32F4 discovery board by using STM32CubeMx. I read manuals about how to use this microphone with STM32F4 discovery board and done my settings based on the figures on these manuals. However, at the end I ju...
If 1-layer PCB is used for LPS22 or LPS25, the pin 3 connection to GND requires some complication of the PCB.Is this pin 3 really connected to some internal circuit and must be connected to GND or it may stay unconnected?At least, when pin 3 is uncon...
The HTS221 has an internal heater to "speed up the sensor recovery time in case of condensation".How do I identify a condensation state?How long the heater has to be activated, in order to recover from condensation state (I want to estimate power con...
May I know what information will be read back from 0xc0 and 0xc1 from L53L1X?
I am IIS2DLPC accelerometer for Tilt Angle Measurement.I have done 6 Axis Calibration. I can able to measure the Tilt Angle less the 1 degree accuary.Is there any other way, I can measure less than 1 degree accuracy with out Calibration ??Note : Cre...
LIS3DH MEMS digital output motion sensor.Hi every body.I'm using this sensor in 'High-resolution mode'. but after some time (I define timeout = 10 seconds) without detect any motion, put the sensor in 'low-power mode'. if the sensor is moved before t...
Many ST mems sensors allow the user to select an I2C or SPI serial interface by controlling the chipsel (CS) pin.My question is: in case a sensor, used as an I2C slave, gets stuck waiting for the master to acknowledge the read operation, does togglin...
I was going through datasheet of LSM9DS1 (DocID025715 Rev 3) at page# 30/72 according to table-20, the bit number 1 of slave address (SAD) depends on SA1 but I couldn't find what SA1 is any where in the document. While in page# 11/72 according to tab...
According to STMicroelectronics guide on github STMems_Android_Sensor_HAL_Input I'm unable to find device.mk file from <AOSP_DIR>/device/<vendor>/<board>/device.mk.Should i need to make this file at this location ?If yes then what are required to wri...
Dear sirI can use an Apple phone to read sensor data and date time but cannot write new interval time and new date time of RTC? Does Apple phone support NFC to write date?BR,Phil Huang
