What exactly is the role of an embedded systems designer? To answer that question, we need to first know what embedded systems are. In simple terms, embedded systems can be defined as a system that is a combination of computer memory, processor, input/output peripheral devices that have some specific purpose.
An embedded engineer works largely on hardware, their role ranges from coding and testing to debugging mainly hardware but to some extent they work on software as well. One of the basic requirements of an Embedded systems designer or engineer is that one should be thorough with the subject.
An embedded systems engineer should not only have knowledge about hardware terminologies, but an embedded systems engineer is indispensable if they have knowledge in both hardware and linking it to the software.
Some of the technical knowledge that an embedded systems engineer should have are:
- Good understanding of electronic components.
- Ability to solve complex problem statements of the real world.
- Great expertise in programming language including data structures(C, C++, Embedded C).
- Great expertise & understanding of circuit design, functionality, logic flow involved in the system.
- Understanding of Computer Architecture, RAM/ROM memories/ and other peripheral devices.
- Ability to read Datasheet, Reference book for developing software.
- Understanding of Microcontroller and microprocessor: A sound knowledge about how to interface microcontroller and microprocessor with the different peripherals.
- Should know how to analyze schematics and have some knowledge about PCB designing (though it is not mandatory but will always give you an edge over others).
- Should have knowledge about hardware circuit design.
- Good command in writing code for various protocols like UART, I2C, SPI, RS232, etc.
- Understanding of debugging, testing and verification.
- Ready to adapt to new technologies.
