Using INAV Ground Station on Display Screens

I. Introduction

INAV ground control station (GCS) supports using a display to provide you with information about your aircraft and INAV status.
When the aircraft is armed, a message will be displayed. When disarmed, a summary page will be displayed: page cycling has been removed, and no other information is currently available.
Currently, the information on the display cannot be changed.

SSD1306 OLED Display Description

• Specifications: 128x64 resolution OLED display
• Features: Clearly visible in sunlight
  • Compact size
  • Extremely low power consumption
  • Very suitable for aircraft use
    There are many models of SSD1306 modules on the market with varying performance. Some models require additional modifications to work properly, so please choose carefully!

    Modification Steps
    Step 1: Fix I2C Acknowledgment Signal Issue
• Issue: From the factory, because the manufacturer did not bridge D1 and D2, the I2C acknowledgment signal (ACK) cannot be sent.
• Solution: Solder these two pins (near the screen entrance) together with solder. If this is not done, the screen will not display anything.
  Step 2: Disconnect and Capacitively Filter Pin 14

1. Use a blade to cut Pin 14 from the main board (requires physical removal).
2. Solder a 10nF or 100nF capacitor between Pin 30 and the disconnected Pin 14.
   Step 3: Add Resistor to Stabilize Signal

• Solder a 100K resistor between Pin 9 and the disconnected Pin 14.
  If Steps 2 and 3 are not performed:
  The screen may only work when the power is turned on in some cases, and will display random noise or distorted images.
  Hardware Connection
  Connect the following interfaces of the flight controller to the corresponding pins of the display:
• +5V → Power positive
• Ground → Power ground
• I2C SDA → Data line
• I2C SCL → Clock line
