Components of embedded systems
- 2. Components of Embedded Systems
- 3. Microcontrollers An integrated circuit that executes a program -Microcontroller vs. microprocessor -Slower, 16MHz-500MHz -Less memory, fewer features
- 4. Microcontrollers • Connected to other hardware components • Sends commands and receives data
- 5. Microcontrollers Needs to be programmed -Write a program in a language, such as C -Place the program in the mctrlr memory
- 6. Programming Microcontrollers -Write code on a host machine-regular desktop or laptop -Programming the microcontroller-transferring the program from host to the microcontroller
- 7. Using a Programmer Programming hardware can be used to place program in the microcontroller memory
- 8. More on Components of Embedded Systems
- 9. Includes hardware needed for programming
- 10. • Used for any application • Many features included • Made to support DSP functions • Vector instructions • Cheaper but more limited • Rceive information from the environment
- 11. Provide simple information • Thermistor: reports temperature • Photoresistor: report light intensity
- 12. More complicated data • CMOS camera: captures images • Ethernet controller: enables network communication
- 13. Cause events to occur in the environment • Simple actuators -Light-emitting diodes (LEDs)-Small lights -LCD display-simple display
- 14. Complex Actuators • Servo motor: moves something • Ethernet controller: enables network communication
