4. Installation
4.1 Schéma de brochage
Refer to the following diagram for the module's pin assignments to ensure correct wiring with your microcontroller.
Image: Detailed pinout for connecting the module to a microcontroller.
- CON (KEY 1): Confirm Button Interface
- ADD : IIC Data Interface for OLED Screen Communication
- SCL : IIC Clock Interface for OLED Screen Communication
- PSH: Key Interface of EC11 (Push-button switch)
- TRA, TRB: Phase A, Phase B of EC11 (Rotary encoder outputs)
- BAK (KEY 0): Bouton de retour
- GND : Ground Power
- CCV: Alimentation positive 3.3 V
4.2 Attaching the Rotary Knob
To use the rotary encoder, attach the provided knob to the encoder shaft. Ensure it is firmly seated for proper operation.

5. Mode d'emploi
5.1 Rotary Encoder Functionality
- Rotation: The EC11 rotary encoder provides incremental feedback when rotated clockwise or counter-clockwise. This can be used for menu navigation, value adjustment, or other continuous input.
- Bouton: The encoder shaft can be pressed down, acting as a push-button switch. This is typically used for selection or confirmation.
5.2 Dedicated Buttons
- Confirm Button (CON/KEY 1): Activates a selected option or confirms an action.
- Back Button (BAK/KEY 0): Navigates back in a menu or cancels an action.
5.3 OLED Display Usage
The 1.3 inch White OLED display communicates via the IIC (I2C) interface. It can be programmed to display text, graphics, and user interface elements. Libraries such as Adafruit_SH110X (as noted by a user review for SH110X driver) are commonly used for controlling SH1106-based OLED displays with microcontrollers like Arduino.

6. Entretien
- Veillez à ce que le module reste propre et exempt de poussière et d'humidité.
- Avoid exposing the OLED display to direct sunlight for extended periods to prevent screen degradation.
- Handle with care to prevent physical damage to the display or encoder components.
- Ensure proper power supply (3.3V) to avoid damage to the module.
7. Dépannage
- L'écran ne s'allume pas :
- Verify power connections (VCC and GND) are correct and providing 3.3V.
- Check IIC (SDA, SCL) connections for continuity and correct pin assignment.
- Ensure the correct display library (e.g., Adafruit_SH110X) is installed and initialized in your code.
- Confirm the IIC address of the OLED module. Common addresses are 0x3C or 0x3D.
- Rotary Encoder Not Responding:
- Check connections for TRA, TRB, and PSH pins to your microcontroller.
- Ensure your code correctly reads the encoder's state changes and button presses.
- Verify the knob is securely attached to the encoder shaft.
- Les boutons ne fonctionnent pas :
- Confirm the CON and BAK pins are correctly wired and configured as inputs in your code.
- Ensure pull-up resistors are enabled for the button pins if not externally provided.
