Hello Everyone,I am currently using LPUART2 for communication between an MCU (STM32U031) and an MPU (Application Processor).Configuration parameters:Baud rate: 9600Stop bits: 1Parity: NoneData bits: 8Description:Data exchange between MCU and MPU work...
Hi everyone,I am using the X-NUCLEO-GNSS1A1 (Teseo-LIV3F) with a NUCLEO-H753ZI board.The UART2 interrupt is working correctly, verified by "[GNSS_RX] UART RX Callback triggered",but the GNSS module does not send any "$GPGGA" or NMEA sentences.Only bi...
Hi,we have an STM32H735G-DK eval board with product identification DK32H735G$AT3 but can not find the differences to older DK32H735G$AT2andDK32H735G$AT1product versions in the user manual:https://www.st.com/resource/en/user_manual/um2679-discovery-ki...
I would like to test UART Bootloader on my NUCLEO-C092RC.System Bootloader mode can be selected pressing the BOOT (B3) pushbutton while resetting the STM32C092 mcu through RESET (B2) pushbutton and without the ST-Link interference removing JP2, JP4, ...
Title edited to be clear that this is on a NUCLEO-F303ZE board.Hello all.I'm trying to write a simple message via UART to Putty using stm32f303ze microcontroller. I'm using USART2, via ST-link. All the configurations have been confirmed (baud rate, C...
Hello ST Community team,on the MB2046 schematic, there is a button called B3 or Boot mode pin:But the UM3353 (chapter 7.9) mention only B1 and B2:Could you please correct this on the coming doc revisions.Best Regards.II
I am working with STM32H747I -DISCO board I am using CubeMx version 6.15, firmware: H7_V1.12.2, Freertos CMSIS2 - V10.3.1configuration 1 : Generating from touchgfx and configuring Eth other all parameters commented in code (Touchgfx parameters).Here ...
Hello, I’m trying to perform ADC measurements with the STM32H563ZIT. I’ve shared my configuration settings from the .ioc file below. The ADC reading fluctuates by about ±40. When I short the ADC pin to GND, the reading varies between 0 and 30 instead...
Hello,as a first time user of STm32CubeIDE, I wanted to toggle a few IOs with a serial output.I used the JTAG port to connect to the STM32 and program it BUT after the first programing, I can't connect to it anymore.....Here is the pinout that I used...
In the default configuration, the SMPS on the development board is disabled. As such the VDDA18PMU appears to be floating. According to the spec sheet, it says that the pin MUST be tied to Vss when the SMPS in not used. Is there an internal pull d...
