How to choose ADC clock frequency.

Hi, My project goal to digitize a sine wave of frequency 20KHz and voltage varying from 0V to 3.3V using ADC of STM32H743ZI. I am using NUCLEO-H743ZI2.My doubt is how to choose ADC clock frequency so that I would be able to digitize the signal with...

Resolved! What are the correct FLASH page numbers for STM32G0 dual bank devices? It looks like there's an inconsistency between the reference manual and the Nucleo FLASH examples included in the STM32G0 Cube G0 package.

In the datasheet (RM0444) for 512k dual bank devices, it looks like the last page of bank 1 is 127 and the first page of bank 2 is 256 (see section 3.3.1)The flash control register (see 3.7.5) says, the valid values for PNB is from 0 (page 0) to 0x17...

STM32H725 ADC3 DMA

I read the adc value using ADC3 + DMA using STM32H725.​ADC3 channel 0,1,10,11 are reading adc value. ​1) ADC3 + DMA1 : RAM 0x24000000 ~ 0x2401FFFF2) ADC3 + BDMA : Allocate an array to store adc values to SRAM4.In all experiments, the correct value do...

Resolved! Is it safe to use +5 volts for I2C with this MPU?

I'm using a Portenta H7 from Arduino. It hosts the STM32H747 microprocessor. I was wondering if it is safe to use +5 volts for I2C even though the MPU runs at +3.3 volts? To clarify, on how the Portenta H7 is wired up, I'm using the pins associated w...

Resolved! STM32L562CET6 won't enter EXTI callback function.

I am quiet new to STM32 programming and can't get the external interrupt to work.I started with the NUCLEO-L011K4 and wrote my programm without any issues. I switched to my own board (pdf included) and weren't able to get extrenal interrupts to work....
