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...

Using onboard eMMC as mass storage device available over USB?

I'm trying to use an STM32H745I-DISCO to log values from a sensor, append the values on a .txt file on the onboard eMMC, and have the text file accessible when plugging in the board over usb (so using the board as a usb device). In other words, I wan...

Why on different 'STM' boards I get different data?

Why does "httpd_post_receive_data" function makes two cycles to convey the data? It is on STM32F407VG board not a 'NUCLEO'.And the same code on the 'NUCLEO-F207ZG' board makes one cycles, without cutting data?

Ethernet with Azure RTOS on STM32H743ZI2

Hi there,i recently started a new project with a Nucelo-H743ZI2 development board.Previously i have worked with FreeRTOS, but i now i want to migrate to Azure RTOS.My problem:I can not get the ethernet interface to work.It seems like there is no soft...

How to put my TLS certificate from Azure to my software

Hello everyone, I have a custom board based on X-CUBE-AZURE, connecting and sending data to a our own Azure Server. When connecting a device we get security alerts from Azure, telling that we do not use a TLS certificate validation. I have found in m...
