Problem with ADC2 self-calibration in dual mode

Hello ST experts,Recently, I was developing a project with STM32H750I microcontroller, I faced a problem with ADC self-calibration HAL function (HAL_ADCEx_Calibration_Start)!I configured ADC1 and ADC2 in dual simultaneous mode + DMA + Timer with sync...

STM32G0 Minimum EXTI Pulse Width

Hi Folks,I'm working with an STM32G0B1MCT6. In my application I need to be able to react to pulses with a width of about 5 ns. It seems the only way I could pull this off is with the rising edge detection in the EXTI controller, or some additional ex...

I2C Bootloader Slave address

Hi,I’m working on the STM32G491 series. In my current project, the STM32 is configured as an I2C slave and communicates with another processor over I2C.When entering bootloader mode for flashing, the STM32 responds with the slave address 0x5F, which ...

Can I2C pins be in different ports?

Hi,I’m currently implementing I2C in slave mode using the STM32G491 series. Due to pin constraints, we’re considering using SCL and SDA pins from different GPIO ports—for example, SCL from port PA and SDA from port PC. Is it acceptable to assign I2C ...

Resolved! Possible risks of voltage drop in VDD of STM32F3

Hi !I am evaluating the risks associated with STM32F3, where I am speculating a case where the voltage drops in VDD for few microseconds. For an example, let us assume the voltage drops from 3.3V to 3.0V for few microseconds. This occurs every x ms (...
