Software reset issue

1. HAL_NVIC_SystemReset() does not work. it always stays at __NOP(), no reset  for(;;)                              /* wait until reset */ {  __NOP(); }2. Before I implemented ADC with DMA, the soft reset below works. But after implemented ADC with D...

When is it better for prefetch buffer to be enable and when is it better for it to be disable?

DMA memory to memory doesn't work

Hi guys im doing a simple 5 byte memory to memory dma transfer with timer update request.As stm32f407 reference manual said timer8 update is connected to dma2 stream 1.Here is the timer config by cube.And the dma cube config:I started the dma and exp...

STM32L432 and STM32H745 DAC in DMA mode has shifted data output

Hi, I have a problem with DAC output, same problem with STM32L4 and STM32H7. I have to continuously output a step wave (3 levels), for this purpose I use a Timer and DMA in circular mode to output an array of 3 values.The code is very simple, I use a...

Hi all, I am back with another problem!! I am using timer 2 in 103C8 controller for 0.1 Sec time delay. However, it is generating 5 times the calculated delay. My initialization code for this delay is given below. Timer interrupt is enabled.

htim2.Init.Prescaler = 1000;htim2.Init.CounterMode = TIM_COUNTERMODE_UP;htim2.Init.Period = 7200;htim2.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1;htim2.Init.AutoReloadPreload = TIM_AUTORELOAD_PRELOAD_ENABLE;However if I change the prescaler to 200, ...

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
