WP-Event

With a Waypoint-Event, the NC can trigger an output of the FC (digital output or Servo) on a Waypoint Position.

auto distance trigger

If the Option in the FC is used "Auto trigger every x meter", that WP-Event value is also used - in that case the value of the Waypoint will be fix set to 6

WP-Event Value on the Waypoint

When the MK is flying Waypoints, and it reaches the Waypoint, the Value "WP-Event" will be sent to the FlightControl.

In the points between the waypoints, the value is zero.

duration of the WP-Event

The duration of the active WP-Event value is the duration of the Waypoint-Waiting time.

Also there is a setting on the SD-card of the NC (SETTINGS.INI), that sets the minimul time:

• MIN_EVENT_TIME = 2 (Default is 2 seconds)
• that can be used if wou don't want to wait on the waypoints, but the WP-Event must be active a longer time

Assign an output on the FC

There are two possibilities.

• Channel assignment
• Output pattern timing on digital Output 1

Option 1: Channel assignment

• You can use the WP-Event as an Channel input and assign it to a Poti
• This Poti can be used for a Servo Output for example
• So, the Servo would move into a specific position on the waypoint and will stay in that position as long as the WP-Event value is active

Option 2: Output pattern timing

• You can directly assign it to the output as timing for the blinking pattern
• The Option "combine with WP-Event" must be selected
• If you also assign a Swich there (Poti6 in this picture), that switch would dominate the output:

  • Switch in 'on' Position (100%) -> the output is in active ON state and not affected by the WP-Event

  • Switch in 'of' Position (0%) -> the output is in active OFF state and not affected by the WP-Event

  • Switch in 'middle' position -> the output timing is set by the WP-Event value (for example WP-Event = 6 means, the ouput pattern will have a timing of 0.06sec per bit)

showing the WP-Events in the logfile

• The WP-Event value is recorded in the logfile.

• you can show it with the SimpleGpxViewer

Testing the WP-Event value

There is a "hidden feature" fo a test purpose of the WP-Event (in your case the field with the name of that parameter would remain empty - please don't care)

You can simulate the WP-Event-Value on your desk without flying on the field.

• in the MAP-Window of the KopterTool make a right-click on the word "Mode"

• a small window will appear there you can select an ID and a value

  • use the ID 6 with a Parameter -> that will simulate a singe WP-Event; just as if the WP-Duration (and the Setting on the SD-card) would be zero

  • use the ID 7 with a parameter -> the WP event will be active until you would send the value "0" or zse the ID 6 to clear that simulated WP-Event value

please don't use the other IDs - they have different options for testing purpose

Example

• We want to trigger a camera by a mechanical servo or a ShutterCable 4 times on the waypoint

• We want to use the blinking pattern
• We want to simulate that on the ground

settings FC

Simulate the WP-Event

• connect a

  • mechanical servo on the ServoOutput 3 of the FC

  • a ShutterCable to OUT1 of the FC

• Use the ID6 to simulate the WP-Event with different values
• See what happens to the Servo

Notes:

• If the waypoint duration in flight is longer than the Blinking pattern needs for one turn, the blinking pattern starts again from the beginning.
• If you just want one singe turn, choose the Waypoint time (and MIN-Time-Setting on the SD-Card) short enough
• Example1: select only the first bit of the blinking pattern and set the WP-Event value to "100" - the Output will be only active for one seconds (in the next 7 seconds the blinking pattern will output just the LOW-Signal without affect)
• Example2: select 11001100 of the blinking pattern and set the WP-Event value to "50" - the Output will be active for one second - waits a second and will be again active for 1 second
