Microcontrollers and Embedded Systems
-
Introduction to Microcontrollers
- Microcontrollers are compact integrated circuits designed to execute specific tasks within an embedded system.
- They consist of a CPU, memory (RAM, ROM), input/output ports, and various peripherals on a single chip.
-
Components of Microcontrollers
- Central Processing Unit (CPU): Executes instructions and performs calculations.
- Memory (RAM and ROM): Stores data and program instructions.
- Input/Output Ports: Connects microcontroller to external devices.
- Peripherals: Additional components such as timers, analog-to-digital converters, etc.
-
Embedded Systems
- Embedded systems are specialized computer systems designed to perform dedicated functions within a larger system.
- They are found in everyday devices like smartphones, home appliances, automotive systems, etc.
-
Applications of Microcontrollers and Embedded Systems
