Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
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...
Sorry for asking an obvious question...LWIP documentation describes a udp_pcb as "Creates a new UDP pcb which can be used for UDP communication."https://lwip.fandom.com/wiki/Raw/UDPWhen connecting to multiple devices with an IP address each using UDP...
I'm using the example for ModbusF429TCP from a GitHub repo for Modbus and get the following error: undefined reference to 'netconn_set_sendtimeout' I'm unfortunately still very new to STM32 and that's why I'm slightly overwhelmed nowGitHub repo is Mo...
Hello everyone, I am using an internal RTC on STM32L431. After running for 23:59:59 seconds, the time changes to 24:00:00 instead of 00:00:00, and the week day has not been incremented. Why is this?
I am configuring USBD to turn the STM32F4 Discovery into a headphone, meaning it can play music through USB and transmit data from the PDM microphone to the computer. I have completed the music playback part, but I am now working on the recording par...
Hi everyone,I’m working on an STM32C0 setup where TIM1 CH1 (Pin A) and UART RX (Pin B) are physically shorted together, and I’ve encountered some unexpected interrupt behavior. Specifically, the UART RXNE interrupt always triggers before the TIM1 Cap...
I am using the STM32H7B3I-DK for my project. I am trying to integrate uSD card usage with a touchgfx program. I have gotten a simple write to a file working on a non rtos project; however, when I use it in my project with RTOS I keep getting a hard f...
I have followed How to create a file system on a SD card using STM32CubeIDE the best I can using the STM32H7B3I-DK. With this board I do not see the DMA tab under SDMMC1, so I have skipped that. I am failing the f_mount(). I am using a touchGFX proje...
Hello.I have a TIM3 configured to generate a PWM signal with frequency 1 MHz and duration 200 ns using CC1 channel. TIM3 also generates a DMA request on CC1.DMA1 is configured to transfer value 0xFFFF from AXI SRAM to SPI2_TXDR register, triggering t...
Hi,i am developing an embedded software based on the TCP Client example for CubeMX. During tests with large number of packets I have got an hard fault error. It seems that it happens on a re-transmit. The hard fault can be easy reproduced with origin...
Hi folks,I am facing one issue for external flash in memory map mode, I am using stm32U585 . I am unable to write/read/access external flash(NOR) while in memory mode. but in Indirect memory mode all actions are working.but in manual they have give...
