My STM32F302C8T6 only runs the program when the code is loaded. If I reset it or power up, it does not run.
Maybe is a hardware problem since the microcontroller is on a custom board I designed. The problem is the following: The microcontroller only runs the program the moment I load the code, if I reset it or power up the board after a power-off it does n...
Resolved! SMPS with/without LDO comparison
I'm trying to understand the benefits/tradeoffs of the "Direct SMPS supply" and "SMPS supplies LDO" options for the STM327H (red and blue options in the attached figure). Since the LDO adds an extra source of power loss, and the SMPS can supply all d...
Resolved! How to send commands from PC to Nulceo board over ST-Link USB interface (UART)?
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...
PCB (that has STM32F407 as MCU and USB CDC interface is running without error) is not recognized by PC( windows 10).
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...
STM32F767 number of decoupling capacitors
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 ...
How to find out the address of LED?
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 ...
USB HS and FS pin locking of STM32H745IIK mapping
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.
Resolved! Setting D2 and D3 as GPIO inputs on NUCLEO-G0B1RE and power cycling appears to be causing a permanent short circuit between D2 and D3. Can you give me any knowledge or insight about this?
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...
