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...

Continuous SPI transactions using DMA

A little background first. I'm use the STM32F412 in a custom design and not using STM32Cube packages.What I want to do is continuously transmit/receive a fixed number of bytes on a SPI interface (master) using DMA with no software interaction (i.e. n...
