Inav tutorial

Published by Mr. This kept swirling around in my head all night, so much so that I had to get up early and try to figure it out, to the point where I left my house 20 minutes late, oops! Still, I worked it out and confirmed it today on my Taranis and iNav setup for my S builds. The idea is that all the time the model is disarmed, no flight mode preference is sent to iNav, and it uses a default flight mode manual.

This does not effect the switches you use for arming or flight modes, just that instead of using Ch5 for arming and Ch6 for modes, for example, Ch5 would do both.

So simple, and frees up a channel. On the Taranis, arm the model and set the flight mode to Manual. Set the slider on the Arm mode so that it starts just before the position marker and ends at the far right hand side.

The Manual mode should start on the far left side and end just after the position marker. This setting means that the model will be armed for all flight modes, and when the model is disarmed it will be in manual mode.

The rest of the flight mods are set up as normal. Below I have added some images to help show the position markers for the different modes. This tutorial shows you how to get more out of your momentary switch. Its pretty simple to set up the momentary switch to do something, like reset a timer or read out your current altitude.

Few seconds and done. INAV not only has to know where bottom is. It also has to know where all other directions are, and how fast UAV is accelerating in those directions to be able to estimate its position.

For this, advanced, or 6 point accelerometer calibration is required. Order is not important with one exception: during first step, top of flight controller has to positioned up. This is impotrant: we are calibrating accelerometer, not whole UAV. Even is FC is mounted upside-down, during first step, FC has to to positioned upwards. Worth remembering: calibration values can be restored via CLI when flight controller firmware is updated.

It is hardware, not software dependent. Calibration should be executed when new hardware is used. Notify me of follow-up comments by email. Notify me of new posts by email. This site uses Akismet to reduce spam. Learn how your comment data is processed.

Is there a charge for the marine charts and maps? All additional charts are available via in-app purchase. What areas do the marine charts and maps include?

Paweł Spychalski

Are the marine charts and maps the latest editions? Yes, since they download directly from our official chart server. They can be updated at any time during the subscription period.

Are the marine charts and maps stored locally on my device? This means once they are downloaded an internet connection is not needed to use the charts or maps. How much storage space do the marine charts and maps take? Depends on how many charts and maps have been downloaded. Individual charts and maps can be deleted. Typical chart or map takes under 1 MB of storage. Does iNavX need a cell or Wi-Fi internet connection to use the marine charts or maps?

An internet connection is only needed to download selected charts and maps. Once charts and maps are downloaded they can be used at any time regardless of internet connectivity. Note: regular raster and vector charts download once and stay in memory with no further need of an Internet connection. Charts in memory do not expire but chart updates do cease once a subscription ends, and if device memory is reset or the device is replaced, it will require a chart subscription renewal.

What devices is iNavX compatible with? Does iNavX support the device compass? Course over ground can also be used.

I have more than one device, can iNavX be installed on all devices? Alternatively, when you sync any device with your PC or Mac, all apps purchased from the iTunes app store will be installed. This means you purchase an app once and install on all your devices across the same iOS or Android platform.

Does iNavX track my location? This functionality also works without cell service. What Location priority order does iNavX use? Does iNavX work in places where there is not marine chart or map coverage? There is a basic low scale world chart included and the instrument and waypoints functionality is not dependent on available or loaded charts. How much are iNavX updates?

Comparison Table. Does iNavX have analog graphics for instrument data? Yes, tap on any instrument value and an analog graphic is available speed, course, wind, satellites, route, depth. Targets are plotted on the chart with real-world scaling. This includes sending to MotionX and Google Earth apps. Is there a Full Screen mode in iNavX? Yes, with the tap of the screen the chart can be expanded to fill the entire view.

NOAA Charts backup to iCloud if iCloud backup is enabled on the users device, but no chart files are archived to a computer hard drive. What measurement units does iNavX support? Nautical miles, statute miles, kilometers, yards, and meters, true and magnetic bearings, degrees and fractional minutes and degrees minutes and seconds.Published by Mr.

This article is currently based on iNav 2. This document is currently a work in progress and not complete. I recommend checking with the iNav WiKi to check for missed steps. I will not be held responsible for any issues that occur. The first thing you need to do before setting up iNav is to find out the correct target for your flight controller.

To do this, open the iNav Configurator and plug in your flight controller. If iNav is not already installed, you should be taken straight to the CLI tab.

You will be presented with the current firmware version and target of the flight controller, for example. Next select the target from the top drop-down box, followed by the version that you would like to install. There are a couple of things I should mention with regards to updating, some depend on how big an update is being performed.

There are some stages that I gloss over, but they are covered in more detail later on this page. The first thing I always do before performing an update, no matter how big, is connect to iNav, go to the CLI tab, and enter either, for a minor upgrade:.

Another example of backups being useful would be if your flight controller dies, you can just set it up a new flight controller, perform the calibration, and write your backed up settings dump to it. Minor version updates, for example 1. The only difference is that after downloading the firmware from the internet, I will read the release notes to see if anything has changed that may effect the settings on the board. For example, in a past release, the developers changed the multiplier on the current sensor by a magnitude of 10, so previous settings of 12 would now bethis allowed these devices to be tuned more accurately.

Any changes that may effect my settings, I make note of and correct after flashing the firmware. With major version updates, I do things differently. Usually major version updates change the way things work, and older settings may cause issues. Compare the 2 dumps and the differences should be highlighted. Go through the differences between the two dumps and make a decision on whether or not to copy the old value from your previous installation to the new.

If you want to use your old values, insert the value into the new dump file. You should very much treat this as a new install, and test everything thoroughly.

Perform the calibration and write previously backed up settings dump for that version to the flight controller. The first thing I do in the initial config is to calibrate the accelerometer.Published by Mr. I decided to set up my iNav slightly differently to how most people seem to, when perusing the tutorials on YouTube.

Most people just assign multiple switches, each to its own channel, which me seems to be a a waste of channels and b makes things more complicated in iNav. Before people argue that there are 16 channels on SBUS, so what does it matter if we use multiple switches over multiple channels.

The answer is speed and reliability. The Taranis only sends out 8 channels per transmission, therefore if you have more than 8 channels, it takes 2 transmissions to get all the data to the receiver. Of course you can use whatever switches you want, just translate them across. My switch positions are:. You can use whatever switch combinations you like for whichever modes you like; you could even expand to use another switch and add more modes.

The only thing you need to be aware of is that some modes need to work together, for example Altitude Hold needs Angle to be active, so these mode need to be next to each other, this way in iNav we can leave Angle on for Angle and any mode next to it. All iNav parts will need to be completed in the iNav Flight Configurator application.

Our first task is to add a mix for the flight modes on the Taranis. This is the only channel that will communicate the flight mode via SBUS. I set mine to channel 5. All we are doing is testing the position of the switch V1 based on the value V2 returned by it. The confusing part with the front facing switches is that a positive value is returned in the down position, and a negative value in the up position.

The next step is to add the second switch.

Five Flight Modes using One Radio Channel

This step is optional, but it makes sense to me that we are using the switches to change flight modes in iNav, so I also want it to change the flight modes on the Taranis. At the very least, we will get visual feedback on the Taranis its self as to which mode we are in.

One thing to be aware of, the flight modes are 0 indexed, whereas the Logical Switches are indexed from 1.

inav tutorial

In other words, subtract 1 from the Logical Switch number to get the Flight Mode number or add 1 to the Flight Mode number to get the Logical Switch number. I have set my flight modes up as follows:. If you choose not to use flight modes, just use the Logical Switch number in the Special Functions. This is where the actual magic happens. We use the Flight Mode or Logical Switch if you chose not to set up the Flight Modes to set the output for the channel and provide spoken feedback if you wish.

I created custom audio files to read out the flight modes. Remove your props before setting this up, as you will need to plug in your flight pack to power the receiver.

This is correct in iNav version 1. Open iNav Configurator, plug in your flight pack, connect the flight controller to the USB port and click connect. In the above image, I have removed a few flight modes so that we can see what is happening on one screen.

It works in the same way that it would with multiple switches, except you are only dealing with 1 channel. This tutorial shows you how to get more out of your momentary switch.

Majority of them are driven by Betaflight. And this is fine.

Sometimes, pilots would like to try how it feels like to have a full navigation and GPS support.

INAV 2. The list of changes is long, those are the most important ones.

INAV is not perfect. You make a sharp turn, artificial horizon goes nuts and it takes some time for it settles down. Kind of irritating. In this video, I will try to explain what is AHI drift, why it happens and how to fight with it.

And admit that we do not yet know how to fix it for good. There is, or rather was, a small problem tho: Iterm. When P and FF components of the controller are not tuned, Iterm might do crazy things that will surface themselves when you release the stick: airplane might either roll-back or do a follow-through. Today a very popular topic: how to setup INAV on a flying wing — level intermediate. Let's take a look at:. In this episode of INAV Blackbox Analysis, we have something quite common again: everything works well in Acro or Angle mode, but as soon as the pilot enabled PosHold, problems start to appear.

What is async gyro and why it is useful to have it, you can read here. In short worlds: data from gyroscope is read and filtered faster than PID controller updates motor and servo output. Async gyro should not be enabled when gyro and control loop frequency are the same. For example, 1kHz gyro and 1kHz control loop would give worse results than 1kHz synchronous processing. Appropriate options are available only with INAV 1.

In this mode, gyro sampling and filtering is decoupled from PID main loop and executed separately. Gyro task frequency should be kept above Control Loop Frequency. In this mode, Gyroscope sampling and filtering, Accelerometer sampling and filtering, Attitude computation and PID control loop are decoupled and run as separate tasks.

Warning Accelerometer accuracy might be lowered if task frequency is too low. Attitude task frequency should be kept below Accelerometer task frequency. Verify gyro, acc, attitude and PID tasks frequencies. Also verify if you have i2c overclocking enabled. I had all that except of the IC2 overclocking. Oneshot and a F4 flightcontroller.

Should i use async gyro? Im using inav 1. No racing. Only had 2 flights so far, but flys amazing. Why does inav in profiles for a heavy quad with 10 inch props and optional gps assisted recommend asynch gyro? You recomend async none for gps assisted.
