Hardwares :   STM32F103C8Tx , ST-LinkV2  STM32CubeIDE  Pinout&Configuration :  In the System/Core settings, only Debug = Serial Wire is selected, while in the RCC, High Speed Clock(HSE) = Crystal/Ceramic Resonator is selected. The PC13 pin on the microprocessor can be selected GPIO_Output and given LED or any other different name as the Label name. Clock Configuration settings can be made as follows : In the Project Manager  section, only theproject is given a name, STM32CubeID is selected as the Toolchain/IDE. After this step go to the Code Generator section on the left side and select second option from the top " Copy only the necessary library files ". Now it will generate the code when saved with CTRL+S keys. Or you can also generate the code using the " Device Configuration Tool Code Generation " button with a yellow icon in the upper-left menu bar.Now our main.c file will be formed. We'll write several codes here :  We will write the code that will a
