Power Supply: VDD: Supplies positive voltage to the microcontroller. VSS: Ground pin for the microcontroller. VCAP1 and VCAP2: These pins are used for stabilizing the internal voltage regulator and are often connected to a small capacitor. GPIO Pins (PA0-PA7, PB0-PB5, PC0-PC4, PD0-PD4): These pins are configured as General-Purpose I/O (GPIO), meaning they can be configured as inputs or outputs based on the user’s application. These pins can also be assigned special functions such as analog inputs (ADC), Timer inputs/outputs, and Communication peripherals (SPI, I2C, USART). Communication Pins: USART Pins (PA3, PD0, PD1): Used for serial communication via Universal Synchronous Asynchronous Receiver Transmitter (USART). SPI Pins (PA5, PA6, PA7): These pins are used for communication with other devices via the Serial Peripheral Interface (SPI). I2C Pins (PB1, PB2): Used for I2C communication, enabling communication with multiple peripherals using just two wires (SCL for clock and SDA for data). Analog Pins: PA0, PA1, PA2, PC0, PC1: These pins can be used as Analog-to-Digital Converter (ADC) inputs, which allows the microcontroller to read analog signals. Timers: Timer 2, Timer 3, and Timer 4 Pins (PB3, PB4, PB5, PC2, PC3, PC4, PD2, PD3, PD4): These pins are used for PWM output or as timer inputs for measuring external events, controlling motors, or generating precise time delays. Reset and Boot Pins: RESET and NRST: Used to reset the microcontroller manually. BOOT0: Determines whether the microcontroller boots from the flash memory or the system bootloader.Frequently Asked Questions (FAQs)
