(1) cannot run at 84Mhz, it will stuck at Error Handler RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE; RCC_OscInitStruct.HSEState = RCC_HSE_ON; RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON; RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_H...
I have few questions on STM32H745 dual core cortex M7 and cortex M4.i. What is the booting sequence when both the cores are enabled at the same time? Is there any application notes available in details.ii. How both the cores uses the same resource (R...
Hi everyone,I am using STM32G070 Nucleo board and work with I2C and use DMA to reload TXDR or read out RXDR. I built up a master that shall also be able to receive from other masters. Everything works fine so far. Now I want to limit the number of by...
Hi,i'm needing to save the date and time on RTC backup register constantly (like once every second) in order to restore the saved time if the MCU was reseted, but im not sure if this registers could be written so constantly.
I would like to change the pin configuration from GPIO Input to INPUT_CAPTURE_MODE_Channel in the code (dynamically). How to achieve this ?I'm using STM32F103CBT6.Please Help. Thank you.
I was reading related to stm32F07 devices application notes and datasheets for ADC input suggestions. AN4899 rev 2 (pg 22)DS6329 rev18 (pg 101)In order to prevent negative and positive current injection, they say:It is recommended to add a Schottky d...
Hey everyone, I am new to STM hardware and software... Recently got a development board from a third party that's based around the aforementioned microcontroller. From what I gather you can start building on STM projects from STM32CubeMX, however I c...
Uart ConfigurationUart Receive CodeHello,I am working on a project with STM32L4S9 mcu and I am trying to receive data via uart from a GPS module (ublox CAM m8) which is continuously sending data. The problem is that when I am trying to debug with bre...
I am using STM32H757I-Eval Board for our study, I created the project for STM32H757 SDRAM interface. While configuring the SDRAM through FMC. I configured SDRAM1 with Bank 2. After that found that the pin configuration generated by the code genera...
Hello,i tried to implement a I2C slave device on a STM32L486.It is working, but sometimes (after a few seconds, minutes or even hours) it freezes/blocks the SCL line. So the master device (also a STM32) generates a error.I have no glue what happens h...
