How can I calculate and set blanking window width of COMP1?

I have an SM32H723 NUCLEO-144 board. I successfully implemented COMP1. It works, but I have some bouncing at the rising and falling edges (100Hz signal). I found a COMP_OutputBlanking example for NUCLEO-H7A3ZI-Q (No blanking example for NUCLEO-H723ZG...

STM32L151RC6, I'm not clear what TIMx_IN1, TIMx_IN2, TIMx_IN3 and TIMx_IN3 alternate functions 14 (CPRI) are

Working on a STM32L151RC6, I'm not clear what TIMx_IN1, TIMx_IN2, TIMx_IN3 and TIMx_IN3 are (datasheet, alternate function 14, CPRI).Belongs to Analog Comparators or Timers?As far as I figured out, if I select AFIO14, the GPIO pad will be connected t...

Does stm32g4 up-down counting mode support external events?

Hello, if configure stm32g4 in up-down counting mode, does it support external events,such as external pin event or analog comparator events?for example ,rising edge of analog comparator event set TA1 output in up count directionand the same event re...

For a three phase system, I want to stop the pwm of channel 1 using comparator 1, channel 2 using comparator 2, channel 3 using comparator 3. The current of each leg is being fed to concerned comparator. I can't find any method to do that.

Three comparators are fed with three currents of each leg. we want to stop the PWM of concerned leg whenever the current goes beyond the set value of DAC.

STM32L4: COMP1 and COMP2 as TIM1 BREAK2 input sources.

Hi,I am using STM32L476 MCU. I have COMP1 and COMP2 configured in window mode. That's working fine. I would like to have COMP1 and COMP2 as break input sources for TIM1 BRKIN2. Test #1: if I set COMP1 as break input source, that works:LL_TIM_EnableBr...

This is on the STM32L053R8T6 Nucleo Board. Is there an error on COMP1&2 working in Window Mode?

This issue had been brought up almost a year back, and there looks like there has not been a fix to the libraries?So basically, after code generation with STM32CubeMX, under MX_COMP1_Init, hcomp1.Init.WindowMode = COMP_WINDOWMODE_COMP1_INPUT_PLUS_COM...

Resolved! Multiple ADC channels on STM32L072xx

I am using STM32L072xx module and I would like to use ADC4, ADC5 and ADC 17 (Vrefint) at the same time. But I want to use ADC4 with DMA of buffer size 500 or more. It is not necessary to store ADC5 & ADC17 in DMA.Can I use DMA only for ADC 4 and dump...

When giving a Comparator a continuous signal and a sine (or sawtooth) the output isn't a clean PWM

Hello,I am trying to use a NUCLEO - STM32G474RE to dirve a buck converter in current mode. For this I need to use a comparator, and when I test it the outcome isn't what I expected. To verify its normal behaviour, I chose Vref/2 as INM and I plugged ...

Why do STM32L433 comparators wake up the device from Sleep mode but not Stop mode, using Vrefint as the reference voltage?

Resolved! STM32L0xx Comparator2

Hi everyone,I am using comparator 2 to capture a signal of duration 3-5usec. But observed that, I am able to trigger the comparator only when the duration of the signal is >5usec. I was wondering if there is any delay introduced by Vrefint in STM32L0...
