Hello,Configuring the I2S on CubeMX on STM32G431, for which I've connected a microphone in PDM, I want a sampling frequency of 48KHz@16bit.Typically, this requires a PDM frequency of 3.072MHz and a decimation of 64.I wonder why I need to tell CubeMX ...

Hello, I'm testing the STM3240G-eval with the USB host MTP. The goal is to retrieve the photo from a canon EOS 100.The camera uses PTP protocol.As the demonstration code read .wav file, I wrote a wav file to the root of the SD card. The digital came...

Yes, I've received some informations (and the solution) from the FAE but haven't had time to post it here yet... See errata sheet ES0394 - Rev 15 2.3.1 RF system wake-up clock set to HSE/1024 cannot be changed In fact, in my client firmware the RF cl...

Hi @STTwo-32,Thank you for your answer.I checked FLASH->ACR->EMPTY and it is 0x0 after the OTA update and after the NVIC_SystemReset() which seems normal because the address 0x08000 0000 is never read as 0xFFFF FFFF. This location is used by the OTA ...

If I change the "object format code" by PTP_OFC_Association I can get the directories list on the SD card.At least the Canon answers/understands some requests...I tried with Object format code between 0x3000 and 0x3810 without success.May be the Cano...

Unfortunately it seems that you can only preview images/videos but not the file list on the camera itself...

Yes may be...But I already changed this line with the JPEG filter and I added a jpeg image on the root of the SD card (if the STM32 can't read in /DCIM/... subdirectory):USBH_MTP_GetObjectHandles(&hUSBHost, 0, PTP_OFC_EXIF_JPEG, 0xFFFFFFFF, &WavHandl...
