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...
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...
Hi ST Team,I’m working with an STM32F303VET6 and need help with EEPROM emulation. I’m looking for guidance on the correct Flash setup, example code for read/write, and best practices for reliability.Any ready examples or tips for integrating this int...
Hi,Im new to STM and trying to use ADC with DMA in circular mode but the value of my ADC remains at 0. I also tested it with Polling, which works.ICache and DCache : Enable void menu_adc(void) uint32_t adc_buffer[1]; uint16_t adc0; uint8_t flag...
Hello everyone,I'm a beginner in embedded systems and I'm trying to flash my LVGL UI resources to the external QSPI flash (a W25Q64) on an STM32H743IIT6 using OpenOCD. I'm running into some issues with OpenOCD detecting the flash.Here is what I have ...
