What is Embedded Systems Development?

Embedded systems development refers to the process of developing software and firmware that runs on computers called embedded systems which are dedicated to particular functions within a mechanical or electrical system. In contrast to general-purpose computers that can run any software, an embedded system is designed to execute a predetermined set of functions, often with strict constraints on physical size, power, cost, and reliability.

Key Characteristics

• Specialized Functionality: Intended for a dedicated function (like controlling a washing machine, car engine, or keeping track of patient vitals).
• Hardware-Software Integration: Its software suffers from a tight-coupling of the software with the hardware, and it fulfills the platform requirements, usually running on very limited resource device, microcontroller (MCU) or microprocessor (MPU).
• Time-Constrained Operation: Implicitly or explicitly, many embedded systems feature inputs or events that must be responded to within a specific amount of time.
• Resource Limited: More efficient than other applications, for they run usually in less memory, process power, and energy.
• Reliable and stable: Typically, serve functions in which failures are not allowed (e.g. automotive safety, medical devices).

Lets go through a typical workflow through yet another overused embedded system IDE (STM32CubeIDE, Keil µVision or MPLAB X):

Install the IDE and Toolchain

1: Download the IDE from official website.

• Install any necessary toolchains, for example ARM GCC, MPLAB XC.
• If required, install drivers for your developmental board.

2. Create a New Project

Launch IDE and Click on File -> New Project.

Microcontroller or Development board selection

Give the name and location of the project.

3. Configure Project Settings

Pick Wrong Device Family And Part Number

Configures clock, peripherals and middleware

STM32CubeIDE: Configure pins and peripherals with graphical configuration tool

4. Write Your Code

Open your main source file (most likely main. c or main. cpp).

Enter or paste the embedded C/C++ code there.

Include some header files or libraries needed.

5. Build the Project

Press the Build or Compile button.

Error messages or warnings will pop up on the output window.

If you have any problems, repair it and reconstruct it, as desired.

6. Flash the Code to the Device

Attach your development board using USB or programmer

Select the correct debug/programming interface.

Click on Download / Flash to upload the code.

7. Debug and Test

Place breakpoints into your code if required.

Start a debug session.

You may have to debug your code in either IME (Step, run, watch variables, etc …) to see what the issue is.
