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...
Dear ST Support Team,I am currently working with the STM32N657X0H3 microcontroller.We are attempting to use the internal 4.2 MB continuous SRAM (starting at address 0x34000000) as the framebuffer for LTDC.The procedure followed is:• Writing pixel dat...
Hello ST team,I am using Nucleo H753zi board, and I wanted to use X-CUBE-MEMSMIC1 expansion for sound source localization.I have already designed simple PCB to use MEMs microphone and connect it to H7 board's ADC. I want to understand how I can progr...
When I calling NVIC_SystemReset() in the os task, the system will enter into hard fault handler error, so I have to call NVIC_SystemReset() again in the HardFault_Handler() to reset the system, so what is the proper way to call NVIC_SystemReset() in ...
The STRD/LDRD instructions store and load a 64-bit value. Internally, they are broken up into 2x 32-bit accesses.Since the element size is a word and not a double-word, they are not atomic in the same way that a uint32_t is atomic. Questions are:Is t...
We are using the NUCLEO-H753ZI family of boards with the specific MCU being STM32H753ZIT6. We were following this tutorial: https://community.st.com/t5/stm32-mcus/how-to-create-a-project-for-stm32h7-with-ethernet-and-lwip-stack/ta-p/49308/page/2/show...
I am wishing to write two floating point values to flash memory at time. I understand it is best to write 64 bits at a time, hence my writing two floats at once. This question is about using a union to structure the data. This code won't compile for...
Hi everyone,i am using the stm32g0b1cet6 controller. in which I am working with flash memory. I am using the FLASH_WaitForLastOperation function. In that function, one flash SR register's CFGBSY bit is not reset, and due to that all other flash write...
I am able to receive UDP unicast packets on the Nucleo-h563ZI using the netconn API, however I cannot receive broadcast UDP packets (global or subnet). I have attached my lwiopts.h for reference along with the relevant discovery service code below. N...
Hi all,I am implementing a protocol over I2C that requires the STM32 part to act as peripheral and respond to host data reads. I get two types of read transactions: random access, where the controller sends the peripheral address with the WRITE bit s...
Hello,I am working on a UVC (USB Video Class) project using a Nucleo-H755ZI-Q board and Azure RTOS USBX.I have successfully tested the ux_device_video (FS) example on the board. Now, I am trying to migrate this example to High Speed (HS) using an ext...
