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...
I encountered this error when I was trying to flash my custom board with fresh stm32F070C6T6. I used st link v2 for debugging. I updated the firmware of st link v2 right before debugging. NRST floating, BOOT0 connected to 3V3 -> failed (in any mode)N...
Hi, According to mb1363 for the H755 Nucleo, in order to change from the default SMPS to internal LDO supply, to enable 480 MHz clock, I need to change C54/C58 from 100 nF to 2.2 uF. However it appears that there are no capacitors installed on my boa...
I am unable to obtain ADC values and would like some advice.Here is the source code project.https://github.com/katsumat/STM32CubeIDE/tree/main/workspace_1.16.1/ADCCalibration PA0 is connected to GND, PA1 to Vdd, and PA3 to the output of a variable re...
When I tried to compile a new project using the latest firmware lib function (in keil MDK-ARM uVision), I got these warnings:whether compiling my own project or the template project.It seems like stm32f4xx.h has a lot of incompatible redefinitions? H...
