STM32 Basics Tutorial
Introduction
In this STM32 Basics Tutorial, you will learn to use GPIO, USB, SWD, UART, Timer and other peripherals of STM32 microcontroller. This tutorial is for beginners who are new to STM32 microcontroller. We will use STM32CubeMX to generate the code and arm-none-eabi-gcc to compile and stlink-tools or STM32CubeProgrammer to flash the code. See the installation.
For this tutorial, we are using STM32F407VGT6 microcontroller used in STM32F407VG-DISC1 board. You can use any other microcontroller as well. The basic concepts are same for all microcontrollers. Before we works on the microcontroller, we need to know about it.
