The Betaflight OSD (On-Display screen Show) is a strong function that means that you can view crucial flight info straight in your FPV feed. This tutorial will information you thru the steps to arrange and configure the OSD in Betaflight, function the OSD menu, and supply helpful CLI instructions for widespread OSD factor setups.
What’s Betaflight OSD?
Betaflight OSD is a function that overlays flight knowledge comparable to battery voltage, flight time, RSSI, and extra onto your FPV video feed. This function is extremely helpful for monitoring the efficiency and standing of your drone whereas flying. You may even use it as a menu to alter your drone’s settings together with PID, charges, filters, VTX channel and extra.
This tutorial focuses on OSD for analog FPV techniques. In case you are utilizing the DJI FPV System, take a look at this tutorial on easy methods to set it up: https://oscarliang.com/dji-fpv-system-setup/#betaflight-osd-setup.
{Hardware} Necessities
Most Betaflight flight controllers (FC) assist OSD for analog FPV techniques, with just a few exceptions which might be designed particularly for HD digital FPV techniques. This needs to be said within the FC specs.
For an FC to assist OSD in analog FPV system, it will need to have an built-in OSD chip (AT7456E). HD digital techniques don’t require this chip for OSD performance.
Wiring
Join your FPV digital camera and video transmitter to the flight controller. The digital camera sign goes to the “Vin” (video enter) pad on the FC, whereas the VTX sign connects to the “Vout” (video output) pad.
Betaflight Configurations
Enabling OSD Characteristic
Obtain and Set up Betaflight Configurator: https://oscarliang.com/download-betaflight-configurator/. Plug your flight controller into your pc utilizing a USB cable. Open Betaflight Configurator and click on on the Join button.
Within the Betaflight Configurator, go to the Configuration tab and allow the “OSD” function. That’s it—your OSD is now activated.
OSD Tab Interface
Navigate to the OSD tab in Betaflight Configurator. That is the place you configure which parts seem in your FPV feed.
On the left, you’ll see an inventory of OSD parts. Merely activate or off the weather you need to show on the display.
You’ll discover three checkboxes for every factor, these correspond to the three obtainable OSD profiles which you can change between throughout flight. This lets you use fully totally different OSD layouts and parts at any time by flipping a change in your radio. If you happen to don’t want a number of OSD profiles, set “Preview for” to OSD Profile 1, and “Energetic OSD Profile” to OSD Profile 1 as nicely. Then, test the primary field for the factor you need to show.
Configuring OSD Components
Click on on a component from the left-hand menu so as to add it to the preview display, then drag it to your required location.
My ceaselessly used parts embody:
- Battery Voltage: Shows the battery voltage, so when to land and keep away from over-discharging your LiPo.
- Battery Common Cell Voltage: Robotically calculates the voltage per cell, simplifying monitoring (e.g., 16.0V for a 4S battery will show as 4.0V).
- Timer2: That is your flight time, it shows how lengthy the drone has been armed. That is totally different from “Timer1,” which reveals powered-on time.
- Warning: A must have. Shows messages if something is unsuitable with the quad, aiding in troubleshooting.
- Battery Present Draw: Reveals amp attract actual time. It requires a present sensor.
- Battery Present mAh Drawn: Reveals how a lot battery has been consumed. It requires a present sensor.
- Hyperlink High quality
- RSSI dBm Worth: Preferable over RSSI which is a share worth.
- Throttle Place
- VTX Channel: Helpful for confirming the channel in use.
Suggestions for OSD Placement:
- Keep away from Litter: Attempt to not overcrowd your display with an excessive amount of info. Deal with the necessities to maintain your FPV feed clear and readable.
- Use Logical Placement: Place your crucial OSD parts in places the place they’re simply readable with out obstructing your view.
OSD Settings
On the appropriate facet of the OSD tab, you’ll discover varied OSD-related choices, most of which could be left at default. Nonetheless, listed below are some key settings to contemplate:
- Video Format: Select Auto, PAL, NTSC, or HD relying in your digital camera/FPV system. For analog, I like to recommend setting it to “Auto” so it detects the right video format for you. For DJI, Walksnail and HDZero, set this to HD.
- Alarms: Set limits for RSSI, battery capability, flight time, and altitude. When these limits are reached, the info will flash on-screen as a warning.
Working the OSD Menu
Betaflight OSD not solely shows flight info but additionally means that you can entry a configuration menu straight out of your goggles. This menu helps you to modify varied settings of the drone with out connecting to a pc, together with PID settings, charges, VTX energy/channel, and extra. This function is helpful for fine-tuning your quadcopter within the discipline. Be aware that not all choices in Betaflight Configurator can be found within the OSD menu, so that you would possibly nonetheless want your pc or an Android app for full configuration.
To entry the OSD menu, disarm your drone and use your transmitter sticks (mode 2):
- Throttle heart
- Yaw left
- Pitch ahead
Your throttle ought to stay at round heart throughout menu navigation.
Navigating the OSD Menu:
- Pitch Up/Down: Transfer up and down the menu objects.
- Roll Proper: Enter a menu merchandise.
- Roll Left: Return or exit.
- Roll: Change parameter values.
- Yaw Proper: Rapidly save and exit.
- Yaw Left: Return to the final menu.
After making changes, save your settings by going again to the principle menu and choosing “Save & Reboot.”
Altering Betaflight OSD Font
You may change the OSD font by clicking the “Font Supervisor” button situated on the backside proper of the OSD tab. Choose a font preset (I like to recommend “Daring”) and click on “Add Font.”
On this window, you can too add a customized brand, which can seem once you plug within the battery.
Remember that when you’ve uploaded a brand new font, it gained’t present within the preview window, however it’ll show accurately in your goggles.
FAQ and Suggestions
- Q: I’m getting a core temperature warning. Ought to I be involved?
- A: This will occur when the drone is sitting on the bench for too lengthy with out correct cooling. It’s often a non-issue, and you’ll disable this warning within the OSD tab below “Warnings”.
- Q: I’m getting an RSSI warning. Ought to I be involved?
- A: Make sure you’ve set the right RSSI alarm worth. By default, it’s set to -60 which is simply too excessive for ExpressLRS. Alter it to match your system’s sensitivity limits. For instance, for ExpressLRS 250Hz, the sensitivity restrict is -108dBm, so I usually set the warning to be round -93dBm (-15dBm hyperlink margin). You may set this in CLI:
set osd_rssi_dbm_alarm = -93. Extra information right here: https://oscarliang.com/lq-rssi/#What-is-RSSI
