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...
rm0456 describes CKDIV belonging to the FDCAN register structure, However the actual header in the cmsis_device_u5 repo make it a member of the FDCAN_Config_TypeDef. This is missleading! Probably FDCAN_Config_TypeDef. is some structure found in the...
Hello,I use a STM32F777 with FreeRTOS and LwIP. I also run a display control with TouchGFX and partial framebuffer via SPI. I have configured the Ethernet and LwIP as shown in the following link: https://community.st.com/t5/stm32-mcus/implementing-a-...
When connecting via USB to a STM32 board in DFU mode, it is possible to read a serial number from the instance path.However, in runtime, the serial number exposed via USB must be programed by the user... It would be nice then if ST provided the algor...
Post edited by ST moderator to be inline with the community rules for the code sharing. In next time please use </> button to paste your code. Please read this post: How to insert source code. HI ALL: In my project, I use AWD1 to monitor ADC3_CHN...
Hello,I'm using STM32H75x and NOR flash e.g. IS29GL064. I get the NOR demo running but I'd like to do modifications in order to get rid of all the polling stuff.According to the demo, the FMC is configured like this hnor1.Init.NSBank = FMC_NORSRAM_B...
Hello everyone,I'm currently working on a custom board with an STM32H735AGI6, and I'm trying to create the external loader for the MX25LM51245g NOR flash on it. I use the OCTOSPI1 for the communication. I first created a basic project using STM32Cube...
Hi,I am working with an STM32 microcontroller (STM32 C0 & STM32H5 series) and want to implement Modbus communication without using FreeRTOS . Most examples I found are based on FreeRTOS, but I need to handle Modbus protocol in a non-RTOS environment....
Hello, I'm having problems with a simple task: receive blocks of data from UART. The blocks are sequences of 1-300 bytes, that are receiveid with a 1 second interval. The value is stored in one buffer of 350 bytes.When I send a big block of 270 bytes...
Hello all,There might be a possible bug in HAL_UART_DeInit(). When calling HAL_UART_DeInit() when it is already initialized could lead to CPU starvation. Assume that an interrupt fires after calling __HAL_UART_DISABLE(huart); and before huart->Instan...
Hello, I have managed to generate a IP through the LWIP in the STM32 IDE and establish a connection via Ethernet, although now when I upload the files from hasseb/stm32h7_atsame70_ptpd: IEEE 1588 PTP daemon for STM32H7 and ATSAME70 (github.com) I se...
