Stick

PPM Stick

General case

This is the case where the 1x ground unit (or BCS/PCS) sends commands directly to the 1x air unit.

Follow the steps below to perform a correct stick configuration on both units.

Ground unit

  1. Go to Input/Output menu \(\rightarrow\) Digital Input panel.

    Make sure that the following parameters have been configured:

    • Producer: CAP 0

      • Enabled

      • Select the pin to which the transmitter is connected (normally EQEP_A)

      • Edge detection: First rising edge

    • Consumer: PPM 0

    General case (Ground unit) - Digital Input configuration

  2. Go to Connections menu \(\rightarrow\) GPIO panel.

    Verify that the pin to which the transmitter is connected, in this case GPIO 16 (i.e., EQEP A), is set as input.

  3. Go to Stick menu \(\rightarrow\) Transmitter 0 panel \(\rightarrow\) PPM tab.

    Select the brand of transmitter that applies.

  4. Go to Stick menu \(\rightarrow\) Transmitter 0 panel \(\rightarrow\) Output tab.

    Click on Enable and on Remote to send the stick information to the air unit. Please check the recommended values for the configurable parameters described in the Ouput - Stick section of this manual.

    General case (Ground unit) - Output configuration

If all these settings are correct, users can check that ‘Stick PPM 0 not detected’ variable of the GND unit will be true.

../../_images/stick_ppm_detected.png

Stick PPM 0 not detected variable - True

Air unit

  1. Go to Stick menu \(\rightarrow\) Transmitter 0 panel \(\rightarrow\) PPM tab.

    Select the brand of transmitter that applies (make the same configuration as the ground unit).

  1. Go to Stick menu \(\rightarrow\) Transmitter 0 panel \(\rightarrow\) Output tab.

    Just click on Enable.

    General case (Air unit) - Output configuration

  2. Go to Block Programs menu \(\rightarrow\) Stick program \(\rightarrow\) Double click on the Stick block \(\rightarrow\) Edit sources.

    Note

    Normally the user has a Stick Program where the blocks that are related to the stick are implemented, however, the name of the user’s program may be different.

    Input the ground unit address to receive the stick information from that source and put it as the highest priority in the priority table. We recommend a Time Out of 0.4 s.

    ../../_images/stick_block.png

    General case (Air unit) - Stick block configuration

Then, if all is correct, users can check that ‘Stick not detected’ variable of the AIR unit will be true.

../../_images/stick_ok.png

Stick not detected variable - True

And that means that the communication between the GND and the AIR unit is correctly configured.

Simulation case (HIL)

In this case, the user is only using one Autopilot 1x.

So users will have to follow steps 1, 2 and 3 explained above for the ground unit, but also steps 2 and 3 of the air unit configuration. However, instead of entering the ground unit address, select the Local option.

On-board PPM receiver case

In this case, follow the steps below to configure the 1x air unit:

  1. Go to Input/Output menu \(\rightarrow\) Digital Input panel.

    Make sure that the following parameters have been configured:

    • Producer: CAP 0

      • Enabled

      • Select the pin to which the transmitter is connected (normally EQEP_A)

      • Edge detection: First rising edge

    • Consumer: PPM 0

  2. Go to Connections menu \(\rightarrow\) GPIO panel.

    Verify that the pin to which the transmitter is connected, in this case GPIO 16 (i.e., EQEP A), is set as input.

  3. Go to Stick menu \(\rightarrow\) Transmitter 0 panel \(\rightarrow\) PPM tab.

    Select the brand of transmitter that applies.

  4. Go to Stick menu \(\rightarrow\) Transmitter 0 panel \(\rightarrow\) Output tab.

    Just click on Enable.

If all these settings are correct, users can check that ‘Stick PPM 0 not detected’ variable of the AIR unit will be true.

../../_images/stick_ppm_detected.png

Stick PPM 0 not detected variable - True

  1. Go to Block Programs menu \(\rightarrow\) Stick program \(\rightarrow\) Double click on the Stick block \(\rightarrow\) Edit sources.

    Note

    Normally the user has a Stick Program where the blocks that are related to the stick are implemented, however, the name of the user’s program may be different.

    Input the address as Local to receive the stick information from that source and put it as the highest priority in the priority table. We recommend a Time Out of 0.4 s.

Then, if all is correct, users can check that ‘Stick not detected’ variable of the AIR unit will be true.

Stick not detected variable - True

And that means that the communication with the AIR unit is correctly configured.

Stick widget

Veronte Ops - Stick Widget

To configure the Stick widget of Veronte Ops as a control input of 1x, follow the next steps:

  1. Go to Block Programs menu \(\rightarrow\) Stick program \(\rightarrow\) Double click on the Stick block \(\rightarrow\) Edit sources.

    Note

    Normally the user has a Stick Program where the blocks that are related to the stick are implemented, however, the name of the user’s program may be different.

    Add a source with Address 2 (App 2) to receive the stick information from the stick widget (of Veronte Ops) and put it as the highest priority in the priority table. A Time Out of 0.4 s is recommended.

  2. Configure the Stick Widget in Veronte Ops. Please find an example of how to configure it in the Stick widget - Integration examples section of the Veronte Ops user manual.

USB joystick

Veronte software is able to detect USB devices such as joystick. The signals of these devices can be read and configured to send stick information to Veronte Autopilot 1x through the Stick widget of Veronte Ops.

To configure them:

  1. Connect the USB joystick to the computer.

  2. Go to Block Programs menu \(\rightarrow\) Stick program \(\rightarrow\) Double click on the Stick block \(\rightarrow\) Edit sources.

    Note

    Normally the user has a Stick Program where the blocks that are related to the stick are implemented, however, the name of the user’s program may be different.

    Add a source with Address 2 (App 2) to receive the stick information from the stick widget (of Veronte Ops) and put it as the highest priority in the priority table. A Time Out of 0.4 s is recommended.

  3. In Veronte Ops, configure the Stick Widget to be used with a USB joystick. Please find an example of how to configure it in the USB joystick - Integration examples section of the Veronte Ops user manual.

Note

It is also possible to convert USB joystick commands into PPM signals using the Veronte Stick Expander.

Virtual Stick

It is necessary to configure a Virtual Stick to process the stick information received from sources other than PPM (by CAN, Serial, ADC, etc.). This stick data must be stored in user variables, and once the virtual stick is configured, these will be processed as stick control signals.

To configure a virtual stick, follow the next steps:

  1. Go to Stick menu \(\rightarrow\) Virtual Stick panel \(\rightarrow\) Input Variable tab.

    • Enable the virtual stick

    • Enter an update period (0.02 s is recommended).

    • Add the variables containing the stick information in Input Variable field.

    • Select as Stick ok bit a user bit variable to indicate if the Virtual Stick configuration has been properly set.

  2. Go to Stick menu \(\rightarrow\) Virtual Stick panel \(\rightarrow\) Output tab.

    Just click on Enable.

    Note

    If all these settings are correct, users can check the variable previously set as Stick ok bit is true.

  3. Go to Block Programs menu \(\rightarrow\) Stick program \(\rightarrow\) Double click on the Stick block \(\rightarrow\) Edit sources.

    Note

    Normally the user has a Stick Program where the blocks that are related to the stick are implemented, however, the name of the user’s program may be different.

    Add a source with address Local to receive the stick information from the configured variables and put it as the highest priority in the priority table. A Time Out of 0.4 s is recommended.

    Then, if all is correct, users can check that Stick not detected variable is true, which means that the communication is correctly configured.
