HI，I use the G0 serials firstly. I have welded 8 model machines,but I found some similar problems. For exampleOn the NO1 board, I used the pin PF1 be output.The problem is that the voltage of the MCU's reset pin is not High toVDD。So the mcu keeps r...
I am working with the NUCLEO-L552ZE-Q and have made a very simple test circuit to test an open drain output signal. I have the pin configured as an open drain output with no pull up or pull down with the signal pulled up to 3.3V through a 1K resistor...
HelloI am planning to start a Hardware MIDI Control Surface design that incorporates a large quantity of rotary encoders, so I am searching for a prototype / evaluation board that has the most potential for GPIO_EXTI (external / attached interrupts)....
Hello, I have three GPIOs output configured. I'm having some strangeness on two of these that I don't quite understand.I'm using a nucleo STM32L432KC, and I have some custom circuitry attached to the GPIOs (detailed below)The situation I am experi...
My program sets D1, D2 and D3 up as identical GPIO inputs. All are pull-ups. Tests using STM32CubeIDE in debug shows both working perfectly and independently as the circuit is opened and closed to pull the input down and allowing it to pull up agai...
Hi,We are planing to use stm32g4 higher end micro controller 128 pins(107 GPIO). We had faced issue for pin shortage.We want to know JTAG, Oscillator we can use as multi functionality (Ex - Debug as well as GPIO or etc...) functionality ?Pins:PA15 - ...
Hi everyone, I am confuse about I2C pull-up resistors. I use 4 I2C sensors. I am not sure is it true that pull-up resistors count. I use every sensors for pull-up resistors. If I use just one I2C port (I mean one port for all sensors) is it enough?
Currently I only set the MODER register to 0 and set the outputs to 0 with the BRR register since I don't need further configurations. I allready use other PINs with the same configuration and they work. I read that this should work, but on my HW it ...
Hello! I need to know how GPIO speed control is implemented. Unfortunately, no information was found in the documentation. All that is known is that the signal front is growing faster or slower, but why? I need some hardware schematic or diagram etc....
Hi, I am using the STM32 Nucleo F446RE board. I have accidentely changed the PA13 pin, which is assigned to the debugger to a GPIO output pin, which resulted in my debugger not working and now I can't load any new code on the STM. How do I change bac...
