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...
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...
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...
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...
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...
hi, i want read read and write data from external QSPI flash S25FL512.i posted code from below st linkhttps://www.st.com/content/st_com/en/support/learning/stm32-education/stm32-moocs/external_QSPI_loader.html QSPI_READ and QSPI_write function exec...
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...
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 ...
