Control LED light

hey thereI have a project where I need to control light of a LED and dim it. usually we use TIMER PWM GENERATION. for example in CubeMX I set a pin to TIMx CHy and by choosing "PWM Generating CHy" I can easily control LED light using PWM signal.but i...

How do i migrate a code from STM32l4 to STM32U5, is there a way to do that????

RTC smooth calibration and verification?

Hi,I m using the smooth calibrationtim1 is using an external clock 1Hz from signal generator and channel 1 is working in output compare mode generating interrupt every 32 seconds, tim2 is using LSE and channel 1 is in input capture mode.When the inte...

STM32F4 Gated Timer with TIM2_CH3

I want to count the 'high time' of a signal on TIM2_CH3. I simply want to count up TIM2 by using internal clock, but gating it with TIM2_CH3. I don't care about interrupts; I only want to use the counter value to access how much 'activity' has occurr...

one Timer PWM, 2 LEDs

Hey thereI want to use one and only one Timer to generate PWM signal to control 2 LED lights. assume that PWM generated is only attached to one the LEDs. how can I make both of LEDs shine or dim with only one PWM?thanks in advance for any help and hi...
