Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Hi, I am trying to setup USB CDC as virtual COM port on STM32L151. I just enabled it through cubeMX and connected the wires. Windows keep saying device not recognized.I just did the exact same thing with STM32G431. An empty project with just USB CDC ...
Hi Everyone,I'm upgrading our firmware from STM32L432kb with 128k flash memory to STM32L432KC with 256k flash memory. both micro controllers are exactly the same except for the flash memory size difference. To accommodate this change I changed my co...
Hello everyone.This is more of a general RTOS question regarding the approach of task management. I've got everything pretty much working but im certain there is a better solution than mine. I'm using FreeRTOS with the CMSIS v2 wrapper.Background:The...
IssueDebugging is functional when employing the IDE; however, when utilizing the Command Line Interface approach, it invariably remains in a state of connection anticipation.CMD:ST-LINK_gdbserver -d -v -t -cp /opt/ST/STM32CubeCLT/STM32CubeProgrammer...
I am using STM32H735AGI with freertos + lwip + no dcacheI have an udp echo server on the device and a udp echo client in python that runs on the pcThe client sends messages with a length of 3 TCP_MSSIn the following logs the first number is the tick...
Hi,I'm using USB mass storage to receive and store the data to external SPI flash ROM. I hope the SPI interface can be using semaphore method, but when I used osSemaphoreWait function in STORAGE_Write_FS function it might cause the device to timeout ...
I am performing audio acquisition from 4 MP34DT01-M microphones using SAI interface and pdm2pcm library on STM32H743.My first question is about the types of variables used in the PDM and PCM buffers. I am storing data from 4 microphones in 32-bit slo...
Hi,I am working using FDCAN as Classic CAN 2.0B, in STM32U575-EV kit.I am facing issue with FDCAN filtering with Classic Mask mode. There is two cases of filter configuration explained below, in first case it is working as expected but in second case...
When I am trying to create a new project for STM32C011 series microcontroller, STM32 cube IDE not showing it in microcontroller selection list.Do i need to install support/package for STM32C0 series, to create workspace for the STM32C0 workspace.Tha...
I have a question about DMA in the STM32L432 (and presumably similar more most STM32L4* devices). The background is that I'm trying to set up timer #2 driving a DAC, and have the DAC grab new data from a circular buffer via DMA.In the RM0394 referenc...
