Peripheral Interfaces
General – Purpose Input/Output (GPIO): The device has GPIO pins that can be configured as either inputs or outputs. These pins can interface with external components such as buttons, LEDs, sensors, and actuators. The GPIO allows the microcontroller to interact with the physical world and receive or send digital signals.
Analog – to – Digital Converter (ADC): It includes an ADC for converting analog signals from sensors (like temperature sensors or potentiometers) into digital values. The ADC has a certain resolution and sampling rate, allowing for accurate conversion of the analog input into a digital format that can be processed by the CPU.
Digital – to – Analog Converter (DAC) (if available): Some versions may have a DAC, which converts digital signals into analog format. This is useful for generating analog output signals, such as audio signals or control voltages for analog devices.
Serial Communication Interfaces: The microcontroller supports multiple serial communication protocols. These include UART (Universal Asynchronous Receiver/Transmitter), SPI (Serial Peripheral Interface), and I2C (Inter – Integrated Circuit). These interfaces enable the microcontroller to communicate with other devices such as sensors, displays, and other microcontrollers.
