How to generate N pulses at F frequency 50% duty cycle using timer?

I want to generate N numbers of pulses at F frequency and 50% duty cycle for that application what is my timers mode setting is best? (PWM , OC)after N pulse timer stop its out puthow can do it?

Input Capture frequency detection is off

I have been working on a configuration which will allow me to detect the frequency of an external square wave, and then divide the periiod of the signal into smaller segments for executing code. I didn't mean to post this yet, just wanted to save as ...

Is can STM32H750VBT use SDRAM?? It has FMC but cubeMX doesn't have that option, but datasheet told about SDRAM. If I want external RAM of STM32H750VBT then I use PSRAM???

Using two time bases, SysTick and general-purpose timer

I am using a STM32G431RB MCU and the STM32Cube_FW_G4_V1.5.0 package for motion control. In addition to the usual SysTick 1ms time base a second, faster time base is needed to run control loops. I plan to use a general-purpose timer (e.g. TIM2) to imp...

Hi, I am currently trying to understand the FMAC and I have some questions

I found AN5305 and the presentation on the ST website but it doesn't fully answer my questions:How long does it take to calculate a result? Is it one clock cycle for each multiplication and addition?Is it possible to configure the FMAC so that it can...
