program counter is hitting WWDG_IRQHandler without enabling the Watchdog. what could be the problem/ cause for this

Hi,please find the attached register values of WWDG register on Reset positionRegards,Sudheer

Forcing Capture-Compare-Register to clear [STM32H7]

I'm trying to count the number transition during the time another process is taking place. Don't need frequency, just the counts.So I've enabled TIM8CH3 for capture-compare, and have verified that CCR3 does change when there are transitions on th...

Interrupt mapping to NVIC ISR vector

I was looking at the ARM M7 reference manual, and it shows an empty NVIC ISR vector from 0x40 to 0x3fc. When I look at the file startup_stm32h725xx.s it defines specific interrupts mapped to the ISR vector. Are these hard mapped by the EXTI block an...

STM32F767 ZI, Trouble understanding how HAL_I2C_MASTER transmit works. Trying to send 32 bit adc data over I2C

So I am trying to send an ADC value that I receiving on the board over I2C to another device. I have adc_Value as a 32 bit one since the ADC read function on HAL is 32 bits. I want to send this over i2c. Currently I have this.  HAL_ADC_Start(&hadc1);...

Hello! I want to trigger with timer the ADC to convert with interrupt or DMA but my program stops at the adress 0xfff4ea. I did all the settings and I introduced the callback function in main. I think it's a problem with this callback. What is wrong?

What is the maximum baud rate for STM32F439ZI-Nucleo144 when using USART?

I am using 115200 bits/s for now and was wondering if I can increase that. If yes, how much can I go until? I checked the datasheet for this board and nothing was mentioned about the baud rate.

trace_printf using OS_USE_TRACE_SEMIHOSTING_DEBUG works fine with Eclipse and STM32F405, but not with STM32F446 and System Workbench

I have two electronic products that use OS_USE_TRACE_SEMIHOSTING_DEBUG:   Microcontroller  IDE 1. STM32F405     Eclipse 2. STM32F446     System WorkbenchI use ST-LINK/V2 to debug both of them and...
