Can a pin that is configured as an external interrupt be also read?

Pretty much what the Q above says. Is it possible to do a HAL_GPIO_ReadPin on a pin that has been configured as an external interrupt?

What is the meaning of asserted in case of an interrupt in STM32L4 Series Microcontroller?

I am using NUCLEO-L4R5ZI-P devlopment board. I am trying to use USB OTG functionality. I used RM0432 for programming purpose.For e.g. I want to know about Session request protocol interrupt in which reference manual mention: "In device mode, this in...

Resolved! STM32F745 USB endpoint EPENA stuck CDC/MSC

I have an intermittent issue with a USB composite device on STM32F745 where an endpoint is failing to send data back to the PC and then the PC resets the connection.I've applied the interrupt disabling from https://community.st.com/s/question/0D50X00...

My question is can USB CDC be used to transfer text file from an SD card to PC the same way as we copy a file from a USB Flash drive?

I try to make a data logger, I'm using STM32F407 DISCOVERY and store the data into the SD. I have to use the USB port for communication between STM to PC for logging status. Eventually, after recording, I want to download the file the same way we cop...

STM32G030F6 I2C Bootloader V1.2

I am updating STM32G030F6 via the built-in ROM bootloader from another MCU. 2 issues:The i2c ROM bootloader slave address is actually 0x56, not 0x51 as written in AN2606. I discovered this on this ST community thread: https://community.st.com/s/quest...

Resolved! How can I back to use UBS-Link?

My stm32l4 discovery kit iot node b-l475e-iot01 stopped the connection via connector 8, I couldn't do it at all, so I used ST-LINK V2, I got communication, but I can't use the USB again, I didn't touch the hardware, absolutely nothing.

Resolved! How to check the UART Serial Buffer If They Are Available using HAL Library

I am using STM32F429 in my project which connects to an ATmega2560 thru UART. In arduino, there is a function Serial.Available() to check if the serial buffer is empty or not.Is there a function in STM32 that is similar to Serial.Available() in Ardui...

DFU Bootloader mode activation STM32F405

Hello,I tried to develop my first µC board inspired by the " adafruit feather STM32F405 express". For layout I used KiCad and the board is made by Chinese PCB manufacturer JLCPCB. To activate the DFU bootloader, the BOOT0 pin must be connected to 3.3...
