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...

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...
Resolved! How DMA works when is triggered with events?
Hello guys.Im a little confused about dma functionality.My question is that if dma controller can start a peripheral or it just can move data from the peripheral to memory.For example when using adc with dma:Is it dma that start the conversion and mo...
Resolved! STM32 for medical use.
We need STM32 MCU types for use in medical instruments. Does ST have Medical grade STM32 MCU's? It must be recommended for new design with long life time.
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
Resolved! Can the STM32L4 transmit and receive USART over DMA?
Hello, I am inquiring about USART communication using DMA. I am following github.com/MaJerle/stm32-usart-uart-dma-rx-tx tutorial using the low level drivers for a STM32L432. I have reception working with no troubles and I believe my interrupts are be...
