Hi,I am experiencing issues with UART single-wire (half-duplex) communication on an STM32H723. The UART handler reports error code 4 (frame error). I have tried a wide range of configuration settings without success.The same setup works correctly on ...
Hi STM Community,I’m currently working with the NUCLEO-G491RE board and need some guidance regarding DFU (Device Firmware Update) mode.According to the documentation, CN2 is marked as the DFU connector. Based on that, I have soldered 4 pins on CN2. I...
In the UM2407 Rev 5 (Nucleo-H753ZI user manual) on page 29/54, section 7.6.6 there is a warning:USB Micro-AB connector (CN13) cannot power the Nucleo144 board. To avoid damaging the STM32H7, it is mandatory to power the Nucleo-144 before connecting a...
Hello STM Community,I currently have a NUCLEO-U575ZI-Q board and the X-NUCLEO-IKS4A1 motion MEMS and environmental sensor expansion board. I’m looking to add BLE functionality and was considering the X-NUCLEO-WB05KN1.Before proceeding, I’d like to as...
I am using an STM32H755ZQ device and unable to start a debug session using STM32CubeIDE + ST-LINK (SWD).The system uses two STM32 controllers, where firmware is flashed to one controller and data is shared/communicated to the second controller.Debug ...
Hello,I’m working on a project with the NUCLEO-H753ZI board and need to connect multiple devices. I’d like to know:1. How many GPIO pins are 5 V-tolerant for digital input?2. How many GPIO pins are available for general use, both 3.3 V-only and 5 V-t...
Hello STM Community,I am facing a GPIO output issue on the STM32 NUCLEO-WL55JC2 board and would like some clarification.Test case:I am using the following line of code to set a GPIO pin HIGH: HAL_GPIO_WritePin(GPIOA, GPIO_PIN_0, GPIO_PIN_SET); // ...
Hello,I want to use the STLink-V3PWR and OpenOCD in SWD mode. I can just use hla_swd as transport and not SWD otherwise I will get the error "Debug adapter doesn't support 'swd' transport". Is there no possibility to use SWD?BR
Hello everyone, I've finished my project with STM32WBA55 and now I'm going to design a small circuit board. I'm using Altium Designer. I can't access the CAD files for Nucleo WBA55. Can you help me? I don't understand if St.com has changed or is no ...
I have ordered NUCLEO-G491R to test STANDBY mode power consumption. The power consumption measurements are taken via the PPK2 from Nordic.https://www.nordicsemi.com/Products/Development-hardware/Power-Profiler-Kit-2The steps:1. Take STM32CubeMX examp...
