Ask questions and find answers on STM32 hardware set-ups, including schematic-related challenges, debugging probes, power configurations, and more.
I have attached herewith the first iteration of the schematic for my custom stm32 board utilizing the H753ZIT6 MCU.I would like to clear few doubts regarding 1) In the nucleo schematic for the same, STM has used F7 MCU for their ST Link interface, sh...
I used STM32CubeMX to set up a Nucleo board (STM32F411RE) to communicate via I2C with a ADXL345 accelerometer.- RCC & clock settings at default- SDA on PB9 and SCL on PB8- I2C Fast Mode- targeted MDK-ARM toolchain- generated code In `main.c` added th...
Hello, I am using EVLSPIN32G4 and when connect it to my PC via USB I get a device connection error. After performing the following steps, a problem occurs when connecting USB (J8).1. Connecting through J9 pin of EVLSPIN32G4 with STM32 ST-LINK Utilit...
Hi, Can't find the source code for the STM32H7S78-DK preloaded TouchGFX Demo, Where could I find this? Thank you,
Hi, I am going to run a simple external Interrupt excercise on Nucleo-G0B1RE. The push button (PC13) works correctly but the ISR is not working on this pin! The sample code is attached. What is the problem with the Interrupt? #include "main.h" void...
Hello everyone and thank you for taking the time to read my post. The problem I'm encountering is regarding the configuration of MCO.I configured MCOSEL and MCOPRE to use PLLRCLK with a 1 prescaler value. The PLLR clock is configured with a frequency...
We just purchased one STM32U5G9J-DK1 from Digikey. We try to replace the LCD module on it with our own selected display with one MIPI lane. Thus, we are designing a interface board so that it can mate with CN2. And since we are also using a touch scr...
Hello,I'm interested in Power Line Communication and the X-NUCLEO-PLM01A1.I would like to confirm before purchasing. What is the role of the PLM connector (CN1)?Is it a PLC line? If so, is the Lab DC Supply Inout Connector (CN2) just a power supply?...
Hello i m would to learn how to debug the h743, h753, f407, and f410 nucleo board using the STLINK-V3 module, i know the H743 Nucleo board has a build-in stlink, but i just wanna learn to use this STLINK-V3 before my custom design board is ready. Can...
Hello ST Community,I'm encountering difficulties while attempting to connect and debug my STM32 microcontroller, and I'm seeking guidance from the community. I have erased the full chip flash memory and uploaded my code but suddenly I start getting t...
