Double (or float) division does not work

Hi,on STM32H7 I want to divide 25600/1000 - I get always result = 25. Why? What I do wrong?double freq; int odr=25600;   freq = (double) (odr)/1000;Thank you

I am trying to simply turn PA0 HI on an STM32F030F4P6 using Cube IDE. No matter what I do, if I try to write to any GPIO registers (including using the auto generated Inits), I get a Hard Fault. Nothing solves it :(

STM32G0x1 Alternate Functions Clarification

I am designing a board and would like to use the 32 bit timer (TIM2) in encoder mode. Per the block diagram in RM0444:the inputs to the encoder interface are T1FP1 and TI2FP2, which originate from TIM2_CH1 and TIM2_CH2 (highlighted in yellow). It a...

How to stop and then re-start one-shot timer?

I am working on the STM32L4S9AII6 MCU. I have timer 6 configured in 1 shot count up mode. Interrupt is enabled. How do I stop a one-shot timer that is already running? I've tried a bunch of things but no matter what I do I can't get the timer to work...

X-NUCLEO-IDB05A2 not working, stuck on SPI_Reset on STM32F746ZG

Hi all, hope all is well. I've been trying to learn the STM32 by creating a project for myself, and I am stuck on the bluetooth portion of things. I have watched videos, read documentation, etc, and I just don't know where I'm going wrong. I've been ...

For low power, is LL better than HAL?

spi5 will not do less then 8 multiplier.

I set up my spi5 as follows hspi5.Init.Mode = SPI_MODE_MASTER; hspi5.Init.Direction = SPI_DIRECTION_2LINES; hspi5.Init.DataSize = SPI_DATASIZE_8BIT; hspi5.Init.CLKPolarity = SPI_POLARITY_LOW; hspi5.Init.CLKPhase = SPI_PHASE_2EDGE; hspi5.Ini...

I am using STM32L443 processor. When the processor is locked, I reset the processor with NRST with external wdg. The processor is not reset although WDG is working properly.

I checked WDG. The system is working properly. If there is no reset, it resets when I disable the WDG signal. In case of deadlock, I pull to GND myself, but it still does not reset. The only solution is to cut off all energy.
