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...
I have a bunch of following warnings:c:/programs/ARMtools/EmbeddedBSPs/arm-eabi/com.sysprogs.arm.stm32/STM32F1xxxx/STM32F1xx_HAL_Driver/Inc/stm32f1xx_ll_gpio.h: In function 'void LL_GPIO_SetPinMode(GPIO_TypeDef*, uint32_t, uint32_t)': c:/programs/ARM...
Hello everyone,I am using SPI2 of STM32F103RCT6 to communicate with an AT45DB641E DataFlash device. I am trying to understand why the effective SPI data rate is significantly lower than what I expect based on the configured SPI clock.Hardware setupMC...
I would like to use the single USB internal PHY on the STM32H735 to connect to a 2 port hub chip (like the Microchip USB2422) so that I can connect to both a USB stick for firmware upgrades as well as a cellular module. I started connecting everythi...
Hi, I got stuck in the HardFault_Handler every time after editing some code. I'm using FreeRTOS in c++ combination with classes. First I thought this would be a memory issue. After increasing configTOTAL_HEAP_SIZE and configMINIMAL_STACK_SIZE, I was ...
Hi there !I use thi function and work perfectly . But if i try to read the HAL_StatusTypeDef i don't understand why return HAL_OK even if i wrote a wrong address why ???? if i use void HAL_I2C_ErrorCallback(I2C_HandleTypeDef *hi2c) this work wit...
Hi, I am compiling the STM32U0 HAL library and I get errors like this one:/Users/kiwanda/techniek/swexternals/STM32/HAL/Libraries/STM32U0xx_HAL_Driver/Inc/stm32u0xx_ll_comp.h: In function 'uint32_t LL_COMP_GetCommonWindowMode(const COMP_Common_TypeDe...
Hello everyone, I’m looking for some help getting an Ethernet TCP server running using LwIP with FreeRTOS on an STM32. Current status: Hardware: NUCLEO-H723ZG Stack: LwIP + FreeRTOS Development Environment: STM32CubeMX and STM32CubeIDE TCP client/m...
I am trying to create a simple UDP server using the NUCLEO-H743ZI2 board. I will port this to a similar microcontroller in the same family (STM32H750B) once I get it working. I am able to build the example code from this repository: https://github.co...
I have designed a custom board based on the STM32F767ZI MCU. To enable Ethernet connectivity, I integrated the KSZ8081RND PHY, along with the necessary magnetics and an RJ45 connector. You can find the full schematics in the attached PDF.On the hardw...
Hi, HAL_LIN_SendBreak seems to be blocking CPU, is there a way to bring UART TX pin down then wait for timer and bring it up? I have done it making GPIO pin GPIO_MODE_OUTPUT_PP then back to GPIO_MODE_AF_PP but init after takes long time. I was wonder...
