Resolved! Does Unicleo-GUI work with NUCLEO-F767ZI + X-NUCLEO-IKS4A1?

I plan to purchase NUCLEO-F767ZI & X-NUCLEO-IKS4A1 for my project. I just wonder whether the Unicleo-GUI works with the combination of NUCLEO-F767ZI + X-NUCLEO-IKS4A1.Your advice is highly appreciated. Qingshan

How to calculate Altitude from Pressure read from LPS22HB sensor ?

I'm using Hypsometric formula to Calculate Altitude by using Pressure & Temperature. ( Source Code used to read the sensor https://github.com/stm32duino/LPS22HB )The Pressure value & Temperature are not in Sync.. Temperature Increases irrespective of...

Resolved! Reading square wave signals

I am trying to read a square wave, or rather I am trying to detect when a square wave is falling using the Nucleo-F746ZG board. Using CMSIS v2, using STMCubeIDE 10.1The square wave comes from a flow sensor, and every time it goes from high to low an ...

How to connect X-NUCLEO-IKS01A3 to STM32 Nucleo-144 F767ZI can I use normal gpios or do I need to use ST Morpho connector only?

I bought X-NUCLEO-IKS01A3 and I have already an STM32 Nucleo-144 F767ZI board. Now I wanted to connect both so for that I went through the F767ZI user manual which i found the following table then I went through the X-NUCLEO-IKS01A3 document there I ...

Inferencing with Microphone

I have stm32f746 discovery board. I need to get input by microphone, and give it to my tensorflow model. I could find neither a plain documentation nor a video. Can you please inform me how to work with microphone on STM32?Thx for your responses.

Resolved! How to connect MKI197V1 to NUCLEO-F756ZGT via I2C but without an expansion board.

The problem is that the address of the device is unknown, I tried 0xD4, D5, D6, D7, A6 and many others, zero reaction.To check, I use the function:#define SENSOR_ADDRESS 0xD4if (HAL_I2C_IsDeviceReady(&hi2c1, SENSOR_ADDRESS, 2, 10) == HAL_OK) { HAL...

Hello ST Experts , I have a stm32f745 ,which creates a single file and writes a string array in SD card using FATFS, but now I want to create multiple files which appends the PDM2PCM middleware converted PCM buffer values. from the 3 MEMS acquired?

Certain things which are unclear are :1) When I increase the size of the PDM buffer and PCM buffer say to 2000 ,4096 to collect more samples for storing to convert them into a larger file into.wav or mp3 , I find no creation of the file in SD card .T...

using the Motion DI Library and getting hard fault at No source available for "quatErr2EulerErr() at 0x800671c"

Hi, have successfully used the library before on an L476, needed more processing power so porting the project to an F746, however, there is a hard fault when using the motion_DI library. breaking the fault don the error message is No source available...

Resolved! Hello ST Experts , I have a three VM3000 PDM mems interfaced to a STM32f745IETx controller , via I2S2, I2S1 lines and another in SAI2_SAIB block , how do I configure three such in programming while using PDM2PCM middleware , can anybody help me ?

The help will be greatly appreciated . I have to write this raw data extraction of PCM values in onto sdmmc sd card . And could anyone explain me how does the PDM2PCM functions for the mems than ST PDM microphones? I usually find examples of stm32 co...

Resolved! How to connect the LSM9DS1 to a STM32F769i Discovery board

I'm sure this is a very basic question, but I am trying to understand exactly how to hook up this sensor to the Discovery board. Do I do this via i2c connection? If so, is there a tutorial somewhere that explains what I need to do?
