STM32 MCUs Products

FFT magnitude calculation messes up the rest of the parts.

I use the CMSIS-DSP library to calculate the Fourier transform, but when I want to calculate the magnitude, I run into a problem. This affects other data (a struct variables )and makes them 0 in the end, the whole program collapses. I don't understa...

[STM32F303] ADC1 watchdog high Threshold limited at min 3500???

Why is there such a limit? As good as this watchdog is, this limit makes it kind of useless. Its it a typo? It worked with 3300 though, when altereing the generated code.

i am designing our stm32l476 board and want to make sure beforehand that i can use Vref refference voltage in the AD conversion or not. i think internal ADC use is available while vbuf+ is conbined with vdda in 64pin package. am i right?

Why does STM32 sometimes hardfault on reboot (thumb vs arm instruction)

STM32L496 micro is hard faulting when power is cycled, but only on some builds of firmware, others are ok. I've been able to track it down to a specific path in the assembly, what looks like is happening is a vector table address is loaded into R3 wi...

Capture egdedirection on input capture with dma

Hello,i am using the STM32F410CBUx and want to detect rising and falling edges with the Timer 5.I get these values with the help of the DMA because the signal edges are close together and i need accurate meassurments. The edges occure all in a short ...

How to use an external signal to trigger ADC on H755ZI?

 Hello,As the title says, I need to use the ADC's external trigger designator pin to trigger the transition. I have done the necessary steps on Cubemx but my code still cannot work.Looking forward to hearing from the forum.Thanks,HAILV /* USER CODE E...

Timer setup to measure the time between 2 events using Input Capture

Hello all,On and STM32F722 I am measuring the speed of an object that is passing between 2 photogates using external interrupts.I would like to automate the time measure using Input Capture direct mode on channel 3 and 4 of timer 4, however I do not ...
