I'm just learning to read and use schematics and I found that while physically the MCU (STM32F407VG on my STM32F4 Discovery board) is marked U4 as the part number on the PCB, the schematic (Section "STM32Fx" of "MB997-F407VGT6-D01_Schematic.pdf") sho...

I was trying to write a simple UART driver using polling method to run on my Nucleo-F303RE. I tried 2 different approaches:I wrote the function intpolldriver() to write an integer value between UART4 and UART5 in the main.c, called it in main() and c...

I am new to STM32CubeIDE and I was trying to write a simple UART driver using polling method. I was successful when I wrote the function in the main.c and compiled the code. So, I wanted to make an API of the same function and moved the function to s...

What exactly is the difference between Nucleo boards Nucleo-F303RE, Nucleo-F411RE and Nucleo-F446RE? To me, the data brief seems to suggest that they are the same. Can someone point out the difference? Is it okay if I buy any of these according to th...
