Removing unused sensors from the STEVAL-BCN002V1B board
I'm working on a low powered bluetooth prototype that has several power constraints. I'm thinking of using the STEVAL-BCN002V1B design as a reference point and I excluded several unused sensors by my project requirements. Will the default firmware st...
Issues with echo cancelation with the (FP-AUD-SMARTMIC1) package.
Hello,I am evaluating the echo cancellation and beamforming functions using the package (FP-AUD-SMARTMIC1) that you propose on your site.(https://my.st.com/content/my_st_com/en/products/embedded-software/mcu-mpu-embedded-software/stm32-embedded-softw...
Best and quickest way to clear the LSM6DSL's FIFO when full.
We use the LSM6DSL chip's accelerometer without the gryo in FIFO mode 110b Continuous mode. (If the FIFO is full, the new sample overwrites the older one.) Every fixed period I read the FIFO1 & FIFO2 status bytes and read the number of unread words (...
How to output data to a serial monitor (Putty) instead of the Unicleo GUI
Hello all,I was wondering if there was a way to output the sensor values from the sensortile box to the serial monitor such as Putty. I wanted to use Processing3 along with the serial data to make my own graphical solution.I am aware that the Unicle...
How to get the recorded audio file from the sensortilebox?
I tried sending the raw data through mail from the mobile application st ble sensor but im unable to extract the audio, someone please help me how to store and export the audio through the microphone in the sensortile box
Using FP-SNS-ALLMEMS1 function pack and trying to take audio recordings at a sampling frequency of 4kHz.
I am a novice in firmware development so please forgive my lack of knowledge and experience with this system.I am trying to obtain audio data at a lower frequency. Right now I can create wav files with a sampling frequency of 8k, but I want to go low...
hi,I want to know about the calibration algorithms on algobuilder
I'am using X Nucleo IKS01A3 and working on algobuilder . when I finish the function blocks and see the graphs on GUI unicleo I get the same graphs for both calibrated and non calibrated accelerometer and gyroscope and magnetometer can you help to fin...
Injected conversion mode with 8 MEMS and DFSDM
Hello,I want to realise a project with the STM32 Nucleo F767ZI Development Board where i need to sample audio data from 8 MEMS Microphones. Since the board only features 4 DFSDM filters but 8 input channels i need to multixplex them. What i already k...
I am trying to using LDM6DSL just for it's linear acceleration sensor to detect movement. The values i receive from the sensor are fluctuating a lot even when the sensor is in a steady position?
I have only used the CTRL6_C(15h) and CTRL1_XL(10h) register to configure the linear acceleration sensor and I am reader the value from register 28h to 2Dh.void i2c_write(uint8_t imudevaddr, uint8_t* write_2_reg_addr_data,int No_of_bytes){ HAL_I2C_Ma...
