I2C with 5 MHz - possible?

If I understand STM32H7xx datasheet, I2C peripherals support up to 1 MHz (FM, FM+), 'officially'.I would need an I2C with 5 MHz SCL clock.I tried and have 'overclocked' I2C with 2 MHz which works fine.Based on the clock configuration (e.g. a 50 MHz P...

STM32H743 interfacing with STUSB1602

HelloI need to interface a STM32H743 with a STUSB1602. I want to port STM32F072_MB1303_DRP_SRCING_DEVICE example to my STM32H743 and use it to control 5x STUSB1602. It seem like this example uses RTOS- Has anyone successful done this or can they reco...

STM32G0 - internal flash read operation returns always 0

HelloI have a const variable located in the internal flash memory. When I directly access this variable in flash, the read operation returns always 0 (even when the content of that location in flash is not 0). When I change the code to first copy the...

Using Nucleo 429ZI and implanting a simple SPI code , There are no signals on the SCK Mosi pins when sending data on SPI1

I am using SPI1 as a Master full duplex , and checking in the Nucleo 429 zi   PA5   ------> SPI1_SCKThere is no clock , I using a scope and testing PA5 pin on the Nucleo 429 zi I attach the code , its very short code Here is the link to the pin descr...

STM32H7 Eval board ADC accuracy

Hello everyone,I am currently trying to get the ADC on the STM32H745ZIQ to work like it should according to the AN *Getting started with the STM32H7 Series MCU 16-bit ADC - Application note.On page 3 the spectrum is shown along with the measurement s...

Hello, I created a simple ADC project for the STM32F302R8, for polling operation it works, when I add an interrupt, the value is not read. I attach the code and ask for any suggestions.

#include <stdint.h>#include <stdio.h>#include "stm32f302x8.h"void delay1(void);volatile uint32_t value;int main(void){   RCC->AHBENR = 1U<<28;   RCC->AHBENR |= 1U<<17;   GPIOA->MODER |= (1U<<8); //ADC1_IN5   GPIOA->MODER |= (1U<<9);   ADC1_COMMON->CC...

Read Parallel CMOS ADC using Nucleo-H743ZI2

HI thereI am do a continues read an of ADC a parallel binary data https://datasheets.maximintegrated.com/en/ds/MAX2771.pdf at the speed from 4-16MSPS with nucleo-H743ZI2. The binary data is sent through 2 ADCs where each has a specific channel I(I0,I...
