Study Notes
Introduction to Microcontrollers
- Microcontrollers are small, integrated circuits that contain a processor, memory, and input/output (I/O) peripherals
- They are designed to control specific applications, such as appliances, industrial machinery, and consumer electronics.
- Microprocessors are general-purpose processors that can handle complex tasks, while microcontrollers are designed for specific purposes and have limited capabilities.
- The 8051 microcontroller is a popular and widely used microcontroller architecture
- The 8051 has a number of pins that allow it to interact with external devices. The pins can be configured as inputs or outputs, and they support various communication protocols.
- The 8051 has internal memory for storing instructions and data. It can be used to access external memory for larger capacity.
- Basic programming skills are essential to utilize the 8051's functionality.
8051 Architecture
- The 8051 microcontroller architecture consists of an oscillator and a clock.
- The Program Counter (PC) holds the address of the next instruction to be executed
- The Data Pointer (DPTR) holds the address of data in memory.
- Registers are used for temporary storage of data, while the Stack is used for storing data during subroutine calls.
- The Special Function Registers (SFRs) control various features of the 8051, such as the timers, interrupts, and serial port.
- The 8051's memory is organized into different memory locations.
- The 8051 has input/output ports for interacting with external devices, such as sensors and actuators.
- The 8051 has counters and timers to track events over time.
- Serial data can be transmitted and received through dedicated serial input/output channels
- The 8051 has interrupts to respond to asynchronous events quickly.
