Hello everyoneI'm using a Nucleo board, specifically the L031K6. I'm used to sending UART messages from the board to the PC via the ST-Link USB interface. In this project I wanted to do the other direction going from the PC up to the card over the sa...
The STM32F407 is programmed with STMCube IDE and there is no error during initizalition of the functions; HAL_Init(), SystemClock_Init(); MX_USB_DEVICE_Init().As I expect that virtual com port will be opened while the PCB is plugged into my PC, unfor...
Hi all, I design PCB with STM32F767 in LQFP144 package. I know that design guidelines suggested adding a decoupling capacitor on each VDD pin but by layout (tracks density) I don't have space for capacitors on each VDD pin (elements on only one side ...
I'm studying a Modbus...And i wanna to check my code and I want to check the condition of pin PC13 (LED).How to find out the address of pin C13? If this line printf("Address of variable LED is: %p\r\n", &LED);say to me error "'LED' undeclared (first ...
Hello,I am working on STM32H745IIK controller.I am enabling the FS and HS USB configuration.The pin mapping that I enable is correct or wrong can you please guide me.I am sharing its pin mapping can you please just help to corrects its pin mapping.
My program sets D1, D2 and D3 up as identical GPIO inputs. All are pull-ups. Tests using STM32CubeIDE in debug shows both working perfectly and independently as the circuit is opened and closed to pull the input down and allowing it to pull up agai...
I've been working on programming a custom STM32F103 board for a couple of months, using SWD and an ST-LINK V2. For no apparent reason, since 3 days ago, I've been getting the error: "No STM32 target found!" It was literally working fine when I want t...
I have started to use stm32l432kc Nucleo board of 32 pins, I want to print some text using the SWD method but I don't know how to do it.Any pls guide me how to do it
