Hi everyone, I have some question about DMIC and PDM to PCM audio output.My Board is STM32H735-dk board, and scenario is below:Using on board MP34DT01TR-M DMIC through PDM interface to SAI4 input PDM data (16kHz input, 1 channel)PDM data to PCM data ...
Hi there,I am trying to read and write to an SD card using SDMMC2 from the M4 core on an STM32H755, using an NucleoH755-ZI and a custom SD card shield. The shield connections are simple, short traces, and as follows:SDMMC2_CK -> PD6SDMMC2_CMD -> PA0S...
I am able to successfully load the GenericMQTT project to STM32F769 discovery board. However, Up on selecting "Clear Connection" for the MQTT communication. The program is asking for CA certification. I believe CA certification is not required for Cl...
Hi,We are using the IAR compiler and Cube generated project on STM32L4+ for a new project we intend to code in C++.Because C++ runs constructors of static objects before the main() function at an undetermined order the program hangs. I need to make s...
Hello everyone,I want to make an USB microphone using the STM32CubeIDE. After I configured the USB connection with STM32CubeMX, I wanted to modify the USB device library to make it work in the other direction (from device to host). Therefore I modifi...
Hi,I ported my project from F4 V1.26.2 to V1.27.0 and found an issue related to file corruption on the sd card after transferring the file through Ethernet (by FileZilla FTP). The weird point is transferred file size is correct but the file contents...
I have a USB device in HOST only mode using the CDC middleware to receive data from a barcode scanner set in RS232 mode. This is working accept for the enormous amount of (spurious) host channels interrupt USB_OTG_GINTSTS_HCINT. When I monitor the nu...
Hello,Could you share any examples of I2C communication implementation between STM32 MCU and sensor using Low-Layer (LL) API? I am using STM32L011 MCU and trying to read temperature values from temperature & humidity sensor HDC2080. I found a library...
