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 β’ Connected to other hardware components β’ 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. β’ Used for any application β’ Many features included β’ Made to support DSP functions β’ Vector instructions β’ Cheaper but more limited β’ Rceive information from the environment
- 11. Provide simple information β’ Thermistor: reports temperature β’ Photoresistor: report light intensity
- 12. More complicated data β’ CMOS camera: captures images β’ Ethernet controller: enables network communication
- 13. Cause events to occur in the environment β’ Simple actuators -Light-emitting diodes (LEDs)-Small lights -LCD display-simple display
- 14. Complex Actuators β’ Servo motor: moves something β’ Ethernet controller: enables network communication
