Resolved! I am using the STEVAL-STWINKT 1B having downloaded the latest STM32CubeFunctionPack_DATALOG1_V1.3.0 as verified by the Device List of the ST BLE Sensor v 4.14.4(76) The app shows an error of "Board scanning timed out" in playing the Example Apps.
The device is recognized by the smartphone, but is unable to pair with it even though the ST BLE Sensor recognizes and does connect and download its configuration and provide battery level. It indicates that it is logging DAT files to the SD card and...
Hi Team, I want to learn the i2c features and functions while using STM32F4 Discovery kit based on STM32F411VE and communication with LSM303DLHC. I want to know if there is any deault register selected in LSM303DLHC when no register value is mentioned.
In this for the i2c communication I am planning to use LSM303DLHC for undersatnding the i2c communication and the protocols. I want to learn more about the driver API like i2c_init(), i2c_read(), i2c_read_with_no_register etc.. Kindly suggest me a wa...
Linux Driver for MP23DB01HP PDM Digital Microphone
I'm looking for instructions on interfacing MP23DB01HP Microphone to Cortex-A7 on STM32MP157 through I2S bus.The application note AN5027 is a good starting point but does not mention how to integrate with Linux on Cortex-A7.I've modified the devcie t...
Housing for inclinometer using MEMS, that leads to low deviation over a temperature range from -10°C to 40°C?
(1) Are there best practice examples available?(2) Can I glue the top side of the MEMS to a steel surface? I expect lower temperature deformation than when fixed with the PCB. Or does the steel surface deform the MEMS in the mentioned temperature rag...
H3LIS331: SPI read response is always 0x00
Hello, I am attempting to communicate using SPI with an H3LIS331 accelerometer. The H3LIS331 is on a custom board that originally had a LIS3DSH on it. The LIS3DSH had been working without a problem, but we were looking to expand the acceleration scal...
LIS2DS12 sampling frequency madness
I was using an ISM303DAC as an accelerometer and everything was fine. Unfortunately, the chip was discontinued, and I had to immediately replace it with LIS2DS12 because all of the accelerometer register configurations were the same. I didn't have to...
