STM32 MCUs Embedded software

I have some questions about PDM2PCM library settings.

I tried to use the PDM2PCM library in the STM32L432.I have some questions about PDM2PCM library.1.The values set by an output buffer in the function PDM_Filter().We must use values in the output buffer (= PCM data stream) as uint or int ?2.I am not a...

Sensor Tile Box does not go to DFU mode from Bootloader mode. How can the DFU mode be obtained again?

After uploading the BLEFOTA.dfu file using Dfuse Demo utility, the SensorTileBox is not going into DFU mode anymore. Instead it shows that STM32 is in BOOTLOADER mode as shown in picture. Now, I cannot seem to plug it into DFU mode, the one by discon...

USB HID device processing of reports is delayed..

I am running on a STM32F405 with Cube V1.23.0.I have an HID (actually PID in and out endpoints) device using interrupt transfer for both the out and in messages. This is a High Speed device using the ULPI interface.The out messages has a report type...

Mount FATFS on STM32H735G-DK's external HyperRam chip

Hi,​I'm interested in mounting a dual drive fatfs on the ​STM32H735G-DK's external memory chips connected to the octospi interface (512M NOR flash MX25LM51245GXDI00, 128M HyperRam S70KL1281DABHI023) I'm not familiar with HyperRam and I'm wondering is...

STM32F767zIT6 to PC communication via a USB interface

I am new to STM32 and I have a custom board with STM32F767. I need to receive CAN messages through one of the CAN interfaces and transmit it through the USB interface to a GUI on the PC and also receive CAN formatted messages from the GUI via the USB...

Implement AWS stack to STM32F4

Dear ST experts,I have an STM32F4 board and I plan to connect it to the AWS IoT cloud via a BG96 cellular module. I have found a very similar sample of STSW-STWINCELL and I am trying to transplant the code from STM32L4+ to my STM32F405 MCU. However, ...

bug in CAN HAL on STM32F1 and dual can configuration

Difficulties pinging the STM32H7 which uses LwIP and FreeRTOS. STM32H7 can send the UDP packet to the server but the server cannot send UDP packet to the STM32H7. I cannot ping the STM32H7, what could be the cause here?

Hello everyone,I'm trying to set up the LwIP and FreeRTOS on the STM32H7.Currently I can send UDP packet from the client (STM32H7) to the server (PC),but I cannot ping the STM32H7.There is the main.c in the attachment and the lwipopts, ethernetif and...

Should I have to modify any of the code w/in CDC_standalone from the STM32F469I_Eval/Applications/USB_Device for it to work on an STM32F479?

STM32F723E-DISCO: USB_CoreReset HAL_TIMEOUT waiting for USB_OTG_GRSTCTL_AHBIDL.

I have used STM32CubeIDE to generate init code based on the STM32F723E-DISCO board. I have tried configurations with both FS and HS PHYs enabled and just the HS PHY, both times in Device Only modeIn each case when the HS USB is initialized (MX_USB_O...
