"Tiago" is a known variant/maintainer of specific MultiWii firmware releases (often found on RC forums like RCGroups or MultiWii.com). "Menu v41" refers to the specific version of the GUI (Graphical User Interface) used to configure the flight controller. Here is a guide on how to use the Tiago Menu (MultiWii GUI) v41 .
1. System Requirements Before connecting, ensure you have the necessary drivers and software:
Drivers: You need the Silicon Labs CP210x or FTDI drivers (depending on your specific flight controller board) installed so your computer recognizes the USB port. Java: The GUI is a Java application. You must have the Java Runtime Environment (JRE) installed (Version 8 or newer is usually recommended for legacy MultiWii GUIs). The GUI File: You should have a folder containing MultiWiiConf.exe (Windows) or the shell script for Mac/Linux.
2. Connecting the Board
Connect your Flight Controller (FC) to your computer via USB. Wait for the USB sound; the FC should power up (LEDs will flash). Open the MultiWiiConf.exe application.
3. Initial Setup (The "Menu" Tabs) The GUI is organized into tabs. Here is the breakdown of the most critical sections in v41: A. Serial Port Selection (Top Right)
Look for the drop-down menu on the top right. Select the COM port associated with your board (e.g., COM3, COM4). Baud Rate: Ensure this is set to 115200 (standard for modern MultiWii). Click Connect . You should see text scrolling in the bottom console window saying "MultiWii V2.x". tiago menu v41
B. The "Setup" Tab (Main Dashboard)
3D View: This window shows the model of your quad/plane. Move the board physically; the model should mirror the movement instantly. Sensor Data: You will see the readings for Gyroscope, Accelerometer, Magnetometer, and Barometer.
Troubleshooting: If these values are stuck at 0 or 4095, your sensors are not detected, or the board is defective. You must have the Java Runtime Environment (JRE)
Calibrate Accelerometer:
Place the board perfectly flat on a table. Click the "CALIBRATE_ACC" button. The LED on the board will usually blink rapidly, then turn solid. The GUI values for Pitch and Roll should settle near 0.
