STM32 MCUs Products

Hi, I need to stop a PWM sometimes and in these cases both the low and the high side Pin should be pulled to low. Is it possible to do that?

I am working with a STM32G474 and I want to use a PWM with 390kHz for a boost converter. I generate a PWM with the HRTIM WaveformOutputStart. Using WaveformOutputStop pulls the LPWM to low, but the HPWM remains on high.

Hey there,I want to recieve two SPI signals sharing the same Enable Line, e.g. having exactly the same speed. I record them using the HAL_SPI_Receive_DMA function and count how many times SPI1 and SPI2 filled there respective Buffers. When using HSI ...

Reflash target while connected with X-NUCLEO-LPM01A

Hello,I have a STM32L432 Nucleo32 and want to analyze its power consumption with the X-NUCLEO-LPM01A.I've read that there is the need to open connections to the STLink interface of the target.After that procedure, is there any possibility to reflash ...

Getting a reading from STM32 ADC when connecting a pull-up input pin to GND

Using CubeIDE and a STM32F4 board I'm trying to start an ADC conversion and make one of the two LEDs blink depending on the ADC value - if the value is smaller than a certain limit then one LED should blink and the other stay off, but if the ADC valu...
