Nucleo-L432KC program not starting

Hello, I'm new on this forum.Last time I bought Nucleo-L432KC board. I have very strange issue with flashing binary. I created simple project in STM32CubeMX for blinking LED every 1 second. I use this command to flash:st-flash --reset write blink.bin...

I am having difficulty receiving data on USART2. It is receiving one character when I use HAL_UART_Receive_IT interrupts. I am trying to receive some characters from ADUCM360 USART.

I can see transmitting characters from ADUCM360 to STM32.But it does not capture the incoming characters from STM32 using interrupts. Any help on this very much appreciated. Thank you

LCD display freezes when Tamper Button is pressed on Evaluation Board

Hello,I am using an STM32H7B3I-EVAL board to test some FDCAN and ADC code that I have written. The goal of the code is to do the following:When the tamper button is pressed, send an interrupt that send a message on the CANbusUsing a CAN receive inter...

Full FW compatibility between STM32H743XI and STM32H753XI

Hello,We're currently using the STM32H743XI for a project, but I we need to switch the STM32H753 for supply reasons.From what I could tell, switching to the STM32H753 should be 100% binary compatible, but I'd like to make sure.Is there any document ...

I want to implement IAP program using UART6 on stm32f205.

I am using IAP program of stm32f207 for the same, but it is not working. Please suggest me for the implementation.

STM32H745-DISCO Oscilloscope Demostration not working

I downloaded the software pack from Github STM32CubeH7/Projects/STM32H745I-DISCO/, and followed the instructions in UM2222 manual.I can connect st link com port. But no data is shown on the oscilloscope window.

I am trying to read 3 ADC channels via DMA. One weird thing happen: if I use a breakpoint on the line of the readings, I get the correct values from the ADC. If I don't use a breakpoint, the values are always 0 or random. Can you help me ?

I tried using delays, but they don't solve the problem. Data are retrieved using HAL_ADC_Start_DMA(&hadc1, value, DATA_LENGTH) HAL_ADC_Stop_DMA(&hadc1);here below my intialization and function:void MX_ADC1_Init(void){    ADC_ChannelConfTypeDef sConf...

How Can reset M7 core using M4 core during run time?

LSE Gain margin

Hi,I am using a crystal from AN2867 (ECX-.327-CDX-1293). I'm having trouble starting LSE on stm32g474 mcu.When I calculate gain Margin, I reach 1.24. The expression in the application note also tells us to be careful that the oscillator transconducta...
