GUI - controls

Controls and communication

Comm port

Select the communications port for the OSD

Baud Rate

Unless specified the default baudrate is 115200

The default for Mavlink based systems (APM/PIXHAWK) is 57600

FONT Tools

Edit Font

Editor for currently loaded font file

Write Font

Uploads fontfile from the GUI into the OSD

Load Font

Browse for an alternative font file to load into the GUI

OSD Controls

Read

Reads values from OSD into the GUI

Write

Updates the OSD with values set in the GUI (excludes screen layouts)

Restarts the OSD - recommended after saving changes

---

GUI - configuration options

Voltage

Display Voltage - select if you wish to display voltage on OSD

Use FC main voltage - select this if you wish to use the Flight controllers voltage. If not selected, it will use the OSD voltage from the hardware pins connection (default).

Voltage adjust - use this to adjust the displayed voltage to match the actual battery voltage. Note if voltage is taken from the flight controller this adjustment is not applicable.

Battery cells - set this to the correct number of battery cells. It is only used for the battery capacity status icon.

Voltage alarm - set this to the voltage at which you require the battery voltage to start to flash.

Amperage

Display Amps - select this if you wish to display the instantaneous Amps draw

Display mAh - select this if you wish to display the cumulative mAh consumed during flight

If neither FC or Virtual are selected, the OSD will use analogue input on OSD

Use virtual sensor - select this instead of default hardware sensor to use a software estimation of calibrated current draw against throttle position.

Use FC Amperage - select this instead of deafault hardware sensor to Amerage values from Flight Controller .

Amps adjust - use this to adjust the Amps drawn value. It is recommended to adjust for accuracy against an Ampmeter around 50%

Zero adjust - use this to adjust the Amps drawn when the copter is idle
throttle with a Multicopter

x100 mAh Alarm - use this to set alarm warning for bat capacity. 10 = 1000mah

Amp Alarm - use this to set alarm warning for Current draw

CAL Button - use this if you have a HW current sensor to set correct values

!!NOTE !! - remember to select 5v reference if using analog RSSI

!! NOTE !! See guide for how to calibrate

RSSI

Display RSSI - select this if you wish to display RSSI on the OSD.

If neither FC or PWM are selected, the OSD will use ANALOGUE RSSI from a RX directly connected to the OSD

Use FC - select this if you wish to to use the RSSI value from the Flight Controller instead of the OSD. The FC must configured to support this

Use PWM - select this if you wish to use the PWM RSSI value from a RX connected directly to the OSD

To use an RC channel, select "Use PWM" and configure RCRSSI in config.h

RSSI alarm - set this to the value at which you require the RSSI value to start to flash

SET (Min) - click this to calibrate RSSI minimum value with TX turned off

SET (Max) - click this to calibrate RSSI maximum value with TX turned on

!!NOTE !! - remember to select 5v reference if using analog RSSI

!! NOTE !! See guide for how to calibrate

Reference Voltage

You must select this if you wish to use > 4s

You must select this if you wish to use HW current sensor or Analogue RSSI

!!NOTE!! This requires a smooth power supply to the OSD when enabled

Display Callsign

You must select this if you wish to use callsign display

Enter the callsign in the Box. Use UPPER CASE and NUMERIC only

Further configuration options are available in config.h

Other

Select Metric or Imperial units for display and measurements

Select NTSC or PAL to match your Camera

Display Throttle value - shows throttle value

Throttle display type - shows PWM throttle value or %

Battery Health icon - shows battery icon as a fuel gauge

Reset stats after arm - enable this only if you want to show measurements over a single flight instead of whilst battery connected

Display

Display Flight mode - shows ACRO/HORIZON/RTH/HOLD icon

- Sensors active - also shows sensors if enabled - acc/baro/mag

Display Gimbal - shows icon when gimbal is activated

Display Vario - shows climb / descend rate

Display Altitude - shows the altitude from prime altitude source BARO is used else GPS

Display Timer - displays flight / on timer

HUD

Display Horizon Bar - shows horizon indicator

- HB - shows additional horizon elevation indicators

Display Sidebars - shows vertical HUD sidebars

- SB scrolling - sidebars scroll in direction of change for altitude and speed

- SB direction - indicator arrows for alternative indicator of direction of change for altitude and speed

GPS settings

Display GPS - enables sats / direction to home arrow,/ Distance / Speed

- GPS co-ords - displays GPS co-ords

- GPS altitude - display GPS altitude

- Angle to home - displays angle to home in degrees relative to direction heading

- MAPMode 0 - disabled

- MAPMode 1 - map center = aircraft, relative home position displayed on map

- MAPMode 2 - map center = home, relative aircraft position displayed on map

- MAPMode 3 - advanced hybrid combination of mapmodes 2 and 3

Compass

Display Compass - displays compass / heading indicator

Display Heading - displays heading in -180 +180 degrees

- Heading 360 - displays heading in alternative 0-360 degrees

Alarms

Distance Alarm - use this to set alarm warning for max altitude. Value is 100

Altitude Alarm - use this to set alarm warning for max altitude. Value is 10

Speed Alarm - use this to set alarm warning for max speed

Timer Alarm - use this to set alarm warning for timer (in minutes)

LAYOUT

Using FC OSD switch - choose to enable screen switching by FC OSD switch function

Using RC channel - choose to enable screen switching by a RC channel

OSD ch - in RC channel mode specifies channel used to switch screen

---

GUI - configurable screen layouts

Understanding the concept of how it works

Any 3 can be uploaded to OSD

Use the layout editor to create a layout that is available to the OSD to use

Fields can be enabled or disabled

Fields can be moved around

The layout defines the fields available to view

GUI tab switches or OSD menu can be used to optionally turn on/off fields available. Turning off disables field on OSD layouts irrespective of the layout settings

Controls and what they do

UP/DOWN/LEFT/RIGHT

Click buttons to move the selected field

TOGGLE

Enables/disables the field on the selected layout. Current status displayed

TX LOW/MID/HIGH channel control

Will be enabled when using RC channel enabled in Layout tab

Layout assigned to Low / Mid High switch setting

Layouts can be changed using drop down arrow

Approximate simulated layout can be displayed by selecting the radio button associated with the TX switch position

OSD SWITCH control

Will be enabled when using FC OSW SW enabled in Layout tab

Layout assigned to normal / OSD Switch setting

Layouts can be changed using drop down arrow

Approximate simulated layout can be displayed by selecting the radio button associated with the TX switch position

WRITE to OSD

Click this to upload to layouts and settings to OSD

SAVE Layout

Click this to save any edits made to HUD layouts

SAVE settings to file

Saves the HUD layouts to file for backup

LOAD settings from file

Loads HUD layouts from a previously backed up file

Enable SWITCHES

Click this to set all display switches on - useful when OSD disconnected and to assist in planning layouts

NOTE - when complete, select EXIT to avoid saving switch settings

---

GUI - FC emulator

Use this to simulate a MSP class flight controller connected to your OSD (Betaflight, Cleanflight, iNav etc.)

Primarily used for OSD development

---

OSD - accessing the built in OSD menu

To access the inbuilt OSD menu, with the FC DISARMED:

THROTTLE MIDDLE

YAW RIGHT

PITCH FULL

To navigate the OSD:

PITCH/ROLL sticks are used to navigate

YAW stick is used to adjust / change values

---

OSD - additional configuration settings

config.h
Further settings are available in config.h due to :

memory constraints to leave enabled permanently

rarely used

not yet moved to the GUI

def.h Advanced settings are available in def.h.

Primarily for developers
