More Navi info SD card ect.

Written by Ziggy March 11, 2012, 07:41:00 PM 5779 Views Print

Into the NaviCtrl you can place a Micro SD-Card in the size up to 2GB (in FAT16 formatted).
Here you can save the flight-route and other datas of the Kopter in KML-Format and GPS-Format.
The SD-Card will be plugged in as you can find under Connections into the NaviCtrl.
A detected and initialized Micro SD-Card you can see in the initialization of the NaviCtrl.

If you want to read or change the data on the Micro SD-card, it must be removed from the NaviCtrl and plugged into an appropriate card slot on the PC.

SETTINGS.INI

On the SD-Card from the NaviCtrl there will be automatically a file generated named Settings.ini with the following content:

KMLLOGGING = 500 (Interval (in ms) the logging of the KML-Datas. Default = 500.)
GPXLOGGING = 1000 (Interval (in ms) the logging of the GPX-Datas. Default = 1000.)
MAX_FLYING_ALT = 0 (Input of the max. flight-altitude. Default = 0. See INFO)
MAX_FLYING_RANGE = 0 (Input of the max. flight-radius. Default = 0. See INFO)
DESCEND_RANGE = 0 (Input of the safety-radius for the max flying range. Default = 0. See INFO)
GPS_SBAS_DGPS_ON = 1 (Switch on/off DGPS receiving. Default = 0.)
MIN_EVENT_TIME = 2 (Adjustable trigger. See: Delay Time)
GPSAUTOCONFIG = 1 (1 = the NC writes its own GPS-Configuration (temporary) into the MKGPS. Default = 1.)

INFO
Important settings for license user!

MAX_FLYING_ALT Here you can enter a maximum altitude which is required for i.e. a special license for the commercial use.
If the Kopter reaches that set up altitude mnessage 29 "ERR:Max Altitude" appears over the telemetry display.
If you do not react to this message and you climb further up, 10mtr. above the set up max. altitude the Kopter will switch automatically to the set emergency-throttle/gas Link and sink.
After reaching the regular set up altitude again the Kopter will switch automatically back from emergency-throttle/gas to normal operation.

User without a license get also after reaching the max. altitude the same message but they are able to climb further up.

More informations about this you will find here: Max.Altitude - Example

MAX_FLYING_RANGE Here you can enter a max. flight-radius which is required for the special license and commercial use.
INFO: This value should be smaller as the under "DESCEND_RANGE" entered radius!!!
If the Kopter reaches this radius GPS will be automatically activated. The Kopter will be flown back automatically over the function "ComingHome" into the set up flight-radius.
Here you will see an appropriate message over the telemetry display.

DESCEND_RANGE Here byou can enter a max. flight-radius which is required for the special license and commercial use.
If the Kopter is leaving this radius it will turn automatically with 80% hovering-throttle/gas into a descent flight.
INFO:
The Kopter should not reach that radius with a small set up "MAX_FLYING_RANGE" under normal circumstances.

For user without a license is the setting "DESCEND_RANGE" with no function.

TIP: To change those values you should insert and open the SD-Card directly in ab appropriate slot on your PC. Here you can do the adjustment with an editor.
TIP: License User should activate in the Settings "Miscellaneous (Misc)" the function "SD card missing".
(For your convenient information: In France, i.e., with the beginning of 2012 are those settings now obligation for commercial user and the Kopter MUST come down if it is out of a 150mtr. radius!)

Attention

1. If you need to change those datas please do not use Logging-times under 500ms - that can affect the navigation and lead to failures!

2. After an Update of the NaviCtrl please clear the SETTINGS.INI on the SD-Card.
The new Software will set a new file with the needed values.

stored data - folder "LOG"

During flight the Kopter will create once a folder "LOG" and save some informations (for each flight) on the micro-SD-card in a .KML and a .GPX file.

These are:

ele
time
sat
Altimeter
Variometer
Course
Groundspeed
VerticalSpeed
FlightTime
Voltage
Current
Capacity
RCQuality
RCRSSI
Compass
NickAngle
RollAngle
NCFlag
ErrorCode
TargetBearing
TargetDistance
RCSticks
GPSSticks
Actual Waypoint
Value of the WP-Event
Nick- and Roll-Servo-Value

You can take a look on this informations with the programm "GPX-Viewer" or "MK_GPX (Link)

Presentation of the flight data in Google Earth

In Google Earth you can display and see the saved flight-datas of the Kopter. In the actual Google Earth Version (>6.1) you can display the flight-route
by loading the .KML or the .GPX-file.

Tipp
If you open a .KML file with "Google Earth" and see only red stripes, you have to edit the .KML file.
Here in this file you can change the coordinates like you see here:

Example:
- Wrong: +7.1234567,+53.1234567, 0.000
- Right: +7.1234567,+53.1234567,0.000

(The flight-route will be also displayed in the height if you set up in the properties of the file the Height to Relativ to ground.)

Parameter

The practice has shown that the default parameters (settings) are already sufficient for almost all MikroKopter.
Who wants to do a little bit fine-tuning that can be done in the settings. You can do that in the tabs NaviCtrl and NaviCtrl2.

Debug-Interface

To the Debug-Interface the MK-USB will be hooked up there. Here you can set up the NaviCtrl, download new software or you can get failure information over the KopterTool.

For the data transfer between the Kopter and the PC you can use also a Bluetooth-Module or a Wi232-Module.
The module will be hooked up also to the Debug-Interface of the NaviCtrl. A second module (Bluetooth or Wi232) to receive the datas will be connected to the MK-USB.

Upgrading software

Connect the NaviCtrl over the 10- and 6pole connection plug with the FlightCtrl (see MK-Tower)
Connect the MK-USB to the Debug-Interface of the NaviCtrl - DO NOT place the jumper on the MK-USB.
Now switch ON the Kopter.
Start the KopterTool and click in the Terminal Window (Button Firmware Update and Terminal) on Update Software (serial). Then choose the .hex-file.
The Update-sequence starts and should be done after approx. 1-2 minutes. At the end you can see debug-datas in the Terminal.

Further information for the Update (also if an update fails) you can get here: SoftwareUpdate

INFO

For updating the software you should always use the MK-USB.
If you use for the data-transfer a Wi232 Module or a Bluetooth Module the update can be faulty!

INFO

To flash the bootloader is not necessary and also not possible.
If the processor is defect you can buy a new one with the appropriate bootloader in the Shop.

Error Codes

If you use the GPS-System (NaviCtrl + Compass + MKPGS) on your Kopter and you calibrate the Gyros, you can see for a short time "error 6" + "error 3" in your Telemetry-Display.
This is normal. Because the connection between FlightCtrl and NaviCtrl is briefly interrupted when you calibrate the Gyros .

For all other Failure codes you can find here some Tipps to resolve it: ErrorCodes
