Key Pin Functions
GPIO (General Purpose Input/Output): Most pins in STM32 microcontrollers serve as I/O for controlling and reading external devices. ADC (Analog-to-Digital Converter): Some pins have ADC capabilities to convert analog signals to digital form. SPI (Serial Peripheral Interface): Several pins are dedicated to SPI communication (MISO, MOSI, SCK, CS). USART (Universal Synchronous/Asynchronous Receiver/Transmitter): Pins for UART/USART communication. CAN (Controller Area Network): Some pins support CAN protocol communication. Timers: Several pins can serve as timer channels for generating precise timing or pulse-width modulation (PWM). External Interrupts (EXTI): Certain pins can trigger interrupts when specific external events occur. I2C (Inter-Integrated Circuit): Some pins serve as SCL (clock) and SDA (data) for I2C communication. Debug Interface: Some pins are used for programming and debugging via SWD (Serial Wire Debug) or JTAG.20 FAQs for STM32F412VGT6
