EVE Knob Control Demo in action!

In this project we are going to play with a magnetic sensor, a generic servo, and a Matrix Orbital EVE2 SPI TFT to show position with an on-screen gauge. We wanted to test our new Scoodo EVE2 Shield, play with our 3D printer to make the knob and test the speed of the EVE2-35G SPI TFT on-screen updates with a gauge.

Hardware

  • EVE2 SPI TFT 320x240
  • Arduino Uno
  • AS5048A-TS Magnetic Position Sensor
  • Power Adapter (optional)
  • Generic Servo

Software

  • Arduino IDE

EXPANDED TECHNICAL DETAILS

High-Performance Industrial UI Hub

This advanced project integrates a high-resolution graphical display with industrial feedback sensors for precise mechanical monitoring.

  • BT81x (EVE2) Graphics Core: Uses the Matrix Orbital EVE2 display, which offloads all graphical rendering from the Arduino. This allows for complex animations and high-frame-rate gauges without slowing down the motor control.
  • AMS Magnetic Position Matrix: The Arduino interfaces with a high-precision AMS magnetic encoder to monitor the exact position of a servo-driven shaft with 12-bit resolution.

Interaction

  • Closed-Loop GUI Verification: The TFT display provides a "Real-Time Angle Gauge." The Arduino captures the magnetic sensor data and instantly updates the EVE2's graphical needle, providing the user with a reliable visual of the mechanical state.
