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...
Hey ST-Community,I’m working with an STM32H7S78-DK board and trying to get Ethernet running. TouchGFX and FreeRTOS are working fine, but I’m stuck with lwIP. The task starts, but DHCP never succeeds (the printed IP is always 0.0.0.0). I also tried w...
Hello I am trying to implement I²C slave on a STM32U385RGTxQ in non-blocking mode, on I2C2.To match I²C standard I tried to use the Address macthed interruption but the interruption is never trigged. I used the function HAL_I2C_EnableListen_IT(&hi2c2...
I am not able to erase a section of internal flash of the NUCLEO-H633RE.Using the debugger I see the Flash is all 0x00 before I try to erase. I verify that Flash is not locked i.e.if (*FLASH_NSCR && LOCK) { *FLASH_NSKEYR = 0x45670123; *FLASH_NSKEY...
English language:STM32H7 Ethernet + DMA + Cache Explained + LwIP (EN) One of the most common sources of confusion when working with STM32H7 microcontrollers and Ethernet (via LwIP + HAL ETH) is data cache (D-Cache) behavior.When using DMA (like Ether...
Hello, I am trying to setup TIM5 channel 1 to output a signal on its output pin. I generated the code using STM32CubeMX2. I am getting an assert failed during initialization.mx_system_init() calls mx_tim5_init() which calls HAL_TIM_OC_SetConfigChanne...
Hello, Using STM32F4 USB USB_OTG_HS, PCD_SPEED_FULL for USB Device CDC we are transmitting data to Host.After some minutes the transmission gets stuck. Although the TXFE IRQ is received, no XFRC IRQ happens and consequently TX state is not set back t...
Hi@all Curently i was using STM32F407VGTX but i found that there is no support of snmpv3 on this board so i decided to go for stm32H753ZI. Kindly please suggest that does this board supports snmpv3 or not and if not please suggest me the board that s...
Hello,I currently need to transfer ADC data from a nucleo-n657x0Q to a PC. I've configured the stm32n6 using ST's example on GitHub, but I still don't know how to use the `ux_device_class_cdc_acm_write` function to transfer the data.Can anyone guide ...
Hello Community, I am working on an STM32N657X0H3Q project and have successfully configured both USBX and X-CUBE-FREERTOS (v1.4.0) within the same Application runtime context using CubeMX. My goal is to implement a USB CDC Composite device. Since USB...
I am using STM32H7R7L8H with MX25L12833F external memory. I created a project with has bootloader, application and external memory loader.Before starting this project I opened another to test if I can read/write/erase MX25L12833F. By using XSPI in Qu...
