How accurate are your analog measurements, really?
With NECTO Studio and a few Click boards™, you can easily validate analog signal accuracy across multiple ADCs and DACs - directly from your embedded setup.
This project demonstrates how analog signal validation meets visualization - powered by STM32 and NECTO Studio.
Perfect for engineers, educators, and anyone exploring ADC/DAC calibration and signal accuracy testing in embedded environments.
The Idea: Validate Analog Accuracy in Practice
Our goal was to create a hands-on setup that compares DAC output and ADC readings in real-time. This makes it possible to measure how precisely your analog system converts, reads, and displays voltage values.
It’s a practical demonstration of how signal integrity and data acquisition accuracy can be validated using just a few Click boards.
This setup is ideal for:
- Sensor calibration and testing
- Industrial control validation
- Analog system diagnostics
- Educational demonstrations
Hardware Components Used
| Component | Description |
|---|---|
| Clicker 4 for STM32F7 | A powerful STM32F7-based development board - perfect for real-time data processing and display control. |
| DAC 12 Click | Provides precise analog output voltage using a 12-bit DAC - the source signal for accuracy comparison. |
| ADC 14 Click | Features the MAX11108A, a 12-bit ADC designed for fast, low-power, high-accuracy voltage measurements. |
| ADC 15 Click | Another ADC for cross-verification, providing a side-by-side measurement for improved accuracy analysis. |
| IPS Display 2 Click | Displays real-time ADC readings and DAC output values, giving a clear view of signal accuracy and variations. |
All components are easily connected via mikroBUS™ sockets - no soldering needed, just plug and experiment.
NECTO Studio: Streamlined Development and Debugging
We used NECTO Studio - the complete embedded development environment from MIKROE - to write, compile, and debug the firmware for this project.
NECTO Studio offers:
- Support for multiple MCU architectures (including STM32)
- Pre-built Click board™ libraries for fast setup
- Real-time debugging and project visualization
This makes analog validation and calibration projects easier than ever - even for complex hardware combinations.
How It Works: Analog Validation in Action
- The DAC 12 Click generates an analog voltage signal.
- This signal is fed into both ADC 14 Click and ADC 15 Click for measurement and comparison.
- Results are displayed in real time on the IPS Display 2 Click.
- The system runs on the Clicker 4 for STM32F7, programmed and debugged in NECTO Studio.
This setup helps engineers visualize voltage deviations, test ADC linearity, and ensure the accuracy of their analog front-end design.

ABOUT NECTO
NECTO Studio is a complete, cross-platform IDE for embedded applications providing everything necessary to start developing and prototyping, including Click board™ applications and GUIs for embedded devices. Rapid software development is easily achieved as developers do not need to consider low-level code, freeing them up to focus on the application logic itself. Switching MCUs or even entire platforms requires no redevelopment - simply change the board definition file, recompile, and your application runs perfectly.
ABOUT MIKROE
MIKROE is committed to changing the embedded electronics industry through the use of time-saving industry-standard hardware and software solutions. With unique concepts like Remote Access, One New Product/Day, Multi-Architectural IDE and most recently, the EmbeddedWiki™ platform with more than million ready-for-use projects, MIKROE combines its dev boards, compilers, smart displays, programmers/debuggers and 1850+ Click peripheral boards to dramatically cut development time. mikroBUS™; mikroSDK™; SiBRAIN™ and DISCON™ are open standards and mikroBUS only has been adopted by over 100 leading microcontroller companies and integrated on their development boards.
