Reset state of certain GPIOs in STM32G431x has unknown behaviour(s)

Hi everyone,I am currently migrating from STM32F303x to STM32G431x microcontroller (48-pin package) and started testing the GPIOs in reset state, without any firmware on-board. Also, there are no external HW circuitries connected to the pins (I meant...

I am getting hardfault when trying to change bank mode from single to dual in STM32F765 by making nDBANK = 0 from FLASH_OPTCR register.

Hello there,While I am trying to switch to dual bank mode (by making nDBANK =0) from default(single bank) mode of internal flash with STM32F765 controller, landing up in hardfault.After resetting from hardfault when trying to read nDBANK bit from FAL...

F411 How to Generate 1 micro second interrupt

I am using F411. The sample code in F411 package can generate timer interrupt in terms of millisecond. I tried to play with some of the parameters like Prescaler, etc, but I could not make any difference. Can anyone give some advice on the relations ...

Hello everyone; I need canbus output for the gps project I am working on. Is there a library for nmea0183 messages and canbus? I'm sorry for my bad english.

Causes HardFault Handler while data accessing through Recording mechanism

I am sending some variable's address through UART then reading and getting those data from UART, often my program stucks into hardfault handler to avoid that in handler i just added __NVIC_SystemReset(); Is there any other way to avoid Hardfault han...

Im using the STM32L432 and I need to transmit data to a Raspberry Pi over I²c. In my project the STM32 is a slave and the Raspberry Pi is the master.

I am able to send & receive 1 integer over the I²c bus but I'm stuck how I can send more integers in 1 commando. Can someone help me please?#include "main.h" #include "string.h" #include "stdio.h"   I2C_HandleTypeDef hi2c1; UART_HandleTypeDef huart2;...

I try to adjust the period of my timer to a certain value on the moment a button generates an interrupt.
