Internal Training: You can customize internal training according to the needs of the enterprise.

Authentication Method:
Understand the competency model before training.
Ability evaluation after training:
  • Online Examination
  • Ability Analysis, give learning suggestions
    • The qualified person shall be issued a certificate as proof of vocational skill qualification
    The idea of code layering, the design of portable code, the skills of code decoupling, the abstraction of the hardware layer, the simulation of hardware on the PC, the abstraction of the business layer, the simulation of the business layer on the PC, the automated testing of the business layer on the PC, the writing of architecture design documents, the writing of interface description documents, etc.
    This course is not only an introduction to embedded architecture design skills, but also introduces testability and maintainability design into the design. The end result is that the developed embedded software can be simulated and run on a PC and automated testing.
     
    Training Goal

    • Embedded software developed by programmers is highly portable and maintainable.
    • Automate the testing of embedded software and reduce inefficient regression testing.
    • Let designers write design documents that guide developers' work, rather than just for archiving.
    • Let's start with the work around us. Point out that most of the software is "Italy pasta" type code.
    • Derive solutions - software architecture design, continuous code optimization, and automated testing.

    Training Target： Software Architects, Software Designers, Programmers who develop embedded products.
    Student Foundation:Familiar with C language; Knowledge of at least one embedded microprocessor.
    Teaching Method: Customized Course + Case Explanation + Group Discussion, 60% Case Explanation, 40% practice exercise
    Training Content: 2 Days
