Pin Function Overview:

GPIO (General Purpose Input/Output): Many pins support standard digital input/output functions. These are often used for user interface s like buttons, LEDs, or other simple components. Analog-to-Digital Converter (ADC): Certain pins can function as inputs for an ADC, allowing the microcontroller to read analog signals. Pulse Width Modulation (PWM): Some pins support PWM functions, used for controlling motors, lights, etc. Serial Communication (USART, SPI, I2C): Many pins are associated with serial communication protocols for communication with other devices like sensors, displays, etc. Timers: Many pins are associated with timer functions for creating delays, measuring time intervals, or generating PWM signals. External Interrupts (EXTI): Pins like PA0-PA7 are associated with external interrupts that can trigger actions in response to an external signal. JTAG/SWD: Pins like PC14, PC15 are used for debugging and programming via JTAG or Serial Wire Debug (SWD).
