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...
NUCLEO-G491RE Break at address "0xfffffffe" during FLASH erase
Hello everybody,I'm having big troubles attempting to erase flash memory of my NUCLEO-G491RE. The message I'm getting after calling "HAL_FLASHEx_Erase" function is "Break at address "0xfffffffe" with no debug information available, or outside of prog...
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...

TIMER PWM mode driving stepper motor how to soft start or acceleration time?
i am driving STEPPER MOTOR using TIMER in PWM mode use interrupt for counting PULSES now how can i accelerate motor slowly(acceleration time 200ms) then running at set speed?acceleration time(ex 200ms) is variable how can i do it? Can iuse dma for ve...
16-bit ADC collects samall ADC siganal used by STM32H743 problems
Hi, I use 16-bit ADC to collect small-value ac signals, and then use USART to transmit them to the computer for reading. The following figures are the result I read. The amplitudes of the two signals are respectively 20mVpp and 100mVpp, and we can ...
