Resolved! Problem programming the sensortile with Nucleo

I have recently got a brand new Sensortile and a nucleo L476RG. I checked if the tile was working by connecting the tile to the cradle expansion board (STLCX01V1) and using the bluetooth app from ST (STBLESensor). The system worked and I could view d...

Resolved! On the STWIN SensorTile Wireless Industrial Node, the standard en.fp-sns-datalog1_v1.2.0 firmware behaves differently if using the binary, rather than compiling the code in the STM32Cube IDE.

When I compile the code in the IDE and run it (with the acquisition json file set to activate for 5s, then idle for 10s, and repeat) It activates correctly the first time. However, when coming out of idle the second time, it produces an SD card erro...


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...

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...
