STM32 MCUs Products

I'm using NucleoF401RE. The issue is that GPIO Read pin is always SET. There is nothing connected to board. No pull-up resister connected. When i try to debug, HAL_GPIO_ReadPin always returns Pin_Status as SET.

Code isn't complex, hence i don't understand what could be the problem.char pin_status;pin_status=HAL_GPIO_ReadPin(SENSOR_H1_GPIO_Port,SENSOR_H1_Pin);

copy float's binary content into uint32_t

Hello,I am trying to copy the content of a float variable with memcpy into uint32_t variable. unfortunately the binary content changes after copying. it should be 0xfff00000, like in the float variable. Does anyone know why this happens and how can I...

SPI Clock goes low when Cable Select does

Hello, I am interfacing with a peripheral where code exists for Arduino, but using it as reference for STM32. The SPI mode is 3. The Arduino code works, so I am attempting to reproduce it's methods for communication. An issue I am seeing is tha...

While setting up the clock, if I set PLLM as 8 and PLLN as 360 , it gives same result as when I set PLLM as 4 and PLLN as 180, so what difference does it makes.
