Hi everyone,I want to use my evaluation board's RTC Backup Registers to store some info when not powered. In order to do that i want to connect an CR2032 battery to the Vbat pin of the controller. Below is the part of the schematics of the board show...
Hello, Please help me.I'm a beginner to designing stm32 hardware designs. I need to program my STM32F413VGT3 microcontroller using SWD(Serial wire debugger). Also I need to use SWO option. I designed a circuit for this.1. I want to know about can I u...
I have been trying to get a PWM output from PE9 by following some example online. However no PWM output at PE9 pin. The desires PWM frequency is 20kHz and duty cycle is 50%. Any suggestion what is the problem ?. Thanks.
I wrote a code for stm32h745, masking the M4 core, and debugged it for two weeks without any problems per se, but yesterday, I realized that I could download the code, but in debug, I noticed that the data in RAM changes, and I didn't make any change...
Hi, I was looking at the GPIO on the STLink3 PWR and trying to find some logic analyzer but i dont find any. Someone know if that gpio are able to do logic analyzer and if yes, a software to do that ? Thanks in advance,
Hello ST Community. I have a STM32H755ZI-Q Nucleo board that I seemed to have blown up the STM32 part. I suspect this because the board is getting an overcurrent condition. But have some questions so I can better understand what may have caused this....
Hi, My board is acting strange. - When I use the USB to power the board (jumper JP3 on U5V) the led LD5 turns red ( the board draws more than 500mA). So I power the board with external power supply (5V and JP3 on E5V) but even if i'm able to flash th...
Hello, I have designed a circuit using the STM32F747XIH6, but I am unable to connect and flash the code using ST-Link. I have checked all the connections, and the NRST pin has a pull-up resistor and measures 3.3V. The 25MHz clock signal appears corre...
I just received a NUCLEO-H503RB dev board, and while attempting to use the GPIO_IOToggle example program to test out the board, I could not run the debugger due to the error "ST-Link not detected." I went back to my NUCLEO-H7S3L8 board, it now receiv...
I'm using an ST-Link V2 to stream (over ITM) code coverage data from an STM32G4 via GDB Server on a PC.This works fine most of the time (for many days), but the data stream sometimes drops some of the data. Adding a delay between calls to ITM_SendCha...
