Why You Need Microcontroller Development?

Microcontroller development is essential for creating custom, embedded, low-cost, low-power, real-time, and rapidly prototyped electronic solutions for various applications. It enables engineers to design intelligent devices that automate processes, control systems, and interact with the physical world efficiently.

Microcontroller Development Process

Microcontroller Development Tasks

Define Development Tasks

Analyze and understand the overall requirements of the microcontroller development project. Consider factors such as system environment, reliability requirements, maintainability, and product cost to establish feasible performance indicators.

Software and Hardware Functions

Partition Software and Hardware Functions

A microcontroller system consists of both software and hardware components. In some applications, certain functions can be achieved either through hardware or software. Hardware usage can enhance system real-time performance and reliability, while software implementation can reduce system costs and simplify hardware structure. Therefore, it is necessary to comprehensively analyze these factors and reasonably allocate the proportion of hardware and software tasks.

Microcontroller and Components

Select Desired Microcontroller and Other Key Components

Based on the hardware design tasks, choose a microcontroller and other key components that meet system requirements and offer cost-effectiveness. These components may include A/D and D/A converters, sensors, amplifiers, etc., which should meet system accuracy, speed, and reliability requirements.

Microcontroller Hardware Design

Hardware Design

Using software like Protel, design the circuit schematic of the application system based on the overall design requirements and selected microcontroller and key components.

Microcontroller Software Design

Software Design

Building on the overall system and hardware design, determine the program structure of the software system, divide functional modules, and then proceed with program design for each module.

Microcontroller Simulation

Simulation and Debugging

After completing software and hardware design, integrate and debug both components. To avoid resource wastage, utilize software such as Keil C51 and Proteus for system simulation before producing actual circuit boards. Any issues identified can be promptly addressed.

MCU System Debugging

System Debugging

After completing system simulation, use drawing software like Protel to create the PCB (Printed Circuit Board) layout based on the circuit schematic. Then, hand over the PCB layout to relevant manufacturers for board production. Once the circuit boards are received, to facilitate component replacement and circuit modification, solder the required chip sockets onto the circuit board first. Next, use a programmer to write the program into the microcontroller.
Insert the microcontroller and other chips into their respective sockets, power up the system, and connect other input and output devices. Proceed with system debugging until successful.

Physical Board for Users

Testing, Modification, and User Trials

Upon successful testing and verification, hand over the system to users for trials. Address any actual issues that arise during the trial phase and make necessary modifications for system refinement. Once testing is satisfactory, the system development is complete.

Microcontroller Development Languages


Assembly language

Assembly language is a low-level (low-level) programming language that is closely related to hardware. It maps directly to machine language, allowing programmers to directly control hardware resources.


C language

C language is the most commonly used development language for microcontrollers. It is also a high-level programming language and has good portability and readability. For microcontrollers, embedded C is usually used for development.


C++ language

C++ is an object-oriented programming language based on C language. Although it is relatively rarely used in the field of microcontrollers, some modern microcontrollers have begun to support C++.

Python language

Although Python is not commonly used for traditional microcontroller programming, some microcontrollers such as MicroPython and CircuitPython support the Python language, making development simpler.
