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...
Hello,I'm working on a project which includes: W25Q32 (NOR Flash), File system and USB MSC + CDC on STM32U0 series MCU - STM32U073RCT6.Till now, I've implemented these:- SPI setup and communication with the NOR Flash (W25Q32)- For the file-system par...
Hi all,I have a strange issue that I can't wrap my head around.I have an eMMC chip connected to a STM32U5G9The .IOC file is all standard: with the clock config as follows: However, when I start a debugging session I get stuck in the init function lik...
Hi all,I'm working on an STM32-based system using FreeRTOS, LWIP (static IP), and the Eclipse Paho MQTTClient C library.Problem Summary:MQTT connection is successfully established (MQTTConnect() OK).All SUBSCRIBE operations return SUBACK, everything ...
Hello,I have been playing about with the LTDC_Paint example and have managed to produce screens using my own images.I would now like to start my own project using the STMH750B-DK incorporating the elements of the LTDC_Paint example.I am struggling t...

hi, am using stm32u585iot dev board i need all power code stop and shutdown and standby code for that board?
Hello everyone, I've designed a custom board with STM32H723ZG, previously based on STM32F767ZG. When I connect board with ST Link V2 prog through SWDIO, SWDCLK and GND, I get response that no target has been detected. I'm currently using ST-Link Util...
I'm programming a STM32H503CBUx Timer3. NVIC settings are such that the count down event is trapped in void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef* htim)This is a global interrupt routine that takes care for other timer interrupts as well a...
I am using the USB CDC driver code provided by ST in stm32cubeide, and am trying to figure out a proper minimum heap size. I have found various slightly conflicting answers, but the consensus seems to be that 512 bytes is not enough.In the same appli...
Hi, I am running firmware for USBX MSC device. The example project "Ux_Device_MSC" on demo board STM32U575I-EV. MSC device is enumerated on computer and FATS file system is used. It can transfer file from computer to storage on STM32U575I-EV. I am...
