  Adjustable end-of-travel switches for tiller actuator
Posted by: ironman - Yesterday, 09:29 AM - Forum: General discussion - No Replies

Has anybody put end-of-travel switches in their tiller pilot? I got some microswitches now, but I am not sure yet how to put them in in such a way that I can adjust them. These switches have this long metal strip that I can bend a few times, but rather I'd have some adjustment screw for that. It all has to be tiny. If you have any (adjustable) implementation of end-of-travel switches, please share or describe for inspirational purposes.

Already off-topic, but a rudder angle indicator seems quite difficult to devise inside tiller pilot's lineair actuators. The traditional potentiometer is not practical here. Better would be some magnetic / optical mechanism that counts revolutions of the screw, possibly in combination with the end-of-travel switches. Any experience here?

I cannot get my head around how it is possible to make a PID control without knowing the exact position of the rudder. Without knowing it, you have to guess. But humans do that as well. With one of those big steering wheels, quite often you don't know either, unless someone marked the middle with a piece of tape. But to me that's not optimal, especially for a 'deaf, dumb and blind' autopilot.

  Latch Maximum Rudder Position
Posted by: wdee - 09-19-2019, 07:13 PM - Forum: Feature Requests - Replies (1)

It seems it would be valuable to latch the Maximum-Rudder-Deflection (Port and Starboard) achieved into Pypilot statistics-panel.

Also make it resetable.

This can be used to adjust AP servo-gains; providing a feedback mechanism of effectiveness.

  LCD not working after git update
Posted by: rmvdmrl - 09-19-2019, 01:54 PM - Forum: General discussion - Replies (2)

Hi Sean,

Perhaps I'm doing something totaly wrong but after updating the latest image version 28062019 today with Github (as i've seen you did the +/- 10 buttons) the display is stuck at the bootlogo. I do have the webinterface and I can see it is reading the IMU, i can do level calibration but can not switch the ap on. Have tried both git pull and git clone but with the same result. Hope you can have a look.

Greetings and thanks Rob

  Three questions about gains
Posted by: ironman - 09-17-2019, 01:51 PM - Forum: General discussion - Replies (2)

I'm in the gain tuning phase now, and I'm venturing into the uncertain realms beyond the easy-to-understand P and D gains.

First thing I have noticed that I cannot get ap.pilot.basic.Igain up. As a test, I've left a heading error build up for more than an hour now, but ap.heading_error_int stays zero and the 'bar' in the plugin gains screen does not go up. I'd expected it to be blue by now (see attached image). I checked the code and can't figure it out. What am I thinking wrong?

[Image: attachment.php?aid=540]

Second question is regarding ap.pilot.basic.R and ap.pilot.basic.Rtime. What are they and how can they be used?

Third question is about ap.pilot.basic.FF. Is this only useful with the autoroute plugin or NMEA APB (gps mode) heading changes, or does it also bump up reactiveness to manual (compass mode) heading changes?

  reboot hangs - configure bluetooth modems
Posted by: StoneCrab - 09-16-2019, 12:14 AM - Forum: Bug Reports - No Replies

I am trying to follow the "fix" for correcting the WiFi country not set issue.  The suggested solutions are not working but every step requires a reboot.  Once the operating system clears, and is restarting, it stops on reboot at a line that says:
"stopped configure bluetooth modems connected by UART"

It goes no further until I cut power and repower the Pi.

Exclamation OpenPlotter 2 roadmap
Posted by: Sailoog - 09-14-2019, 01:33 PM - Forum: General discussion - Replies (1)

OpenPlotter 2 is in alpha stage. Now OP consists of independent applications. For the first time, we open the door to the entire Debian family and even to other hardware. However, the most interesting applications remain exclusive for Raspberry.


You can test it installing the latest Raspbian. Since we do not need the recommended software, we recommend just Raspbian Buster with desktop. Then, open a terminal and install the dependencies:

sudo apt update
sudo apt install python-configparser python3-wxgtk4.0 python3-ujson whois

and finally you have to install openplotter-settings, the main application. Go to the repository and download the latest deb package:

After download the deb file, you can install it with double click or typing this in a terminal:

sudo dpkg -i openplotter-settings_x.x.x-xxx.deb

To open OpenPlotter 2 and start playing with it go to the Main menu->Others->OpenPlotter settings. You must install the rest of applications from the list in OpenPlotter Settings.


Alpha Stage
  • OpenPlotter Settings
  • OpenCPN installer
  • Signal K installer
  • Xygrib
  • Network
  • I2C Sensors
  • OpenPlotter Apps Template
  • Pypilot (development)
  • Moitessier HAT (development)
  • Serial Devices Management (development)
  • CAN Devices Management (development)
  • OpenPlotter-Gen (img and NOOBS files)
Beta Stage
  • 1W sensors
  • Actions
  • Dashboards
  • Kplex
  • Signal K filters
Release Candidate
  • Translations
  • OpenPlotter-Gen (img and NOOBS files)
OpenPlotter v2 image and NOOBS release
  • Using this new structure we will be able to add new applications without waiting for a new major release (OpenPlotter 3).
  • Basic: we will have the usual img and NOOBS files for Raspberry Pi.
  • Intermediate: you will be able to install OpenPlotter on any computer running any Debian based OS like Ubuntu, Mint...
  • Advanced: OpenPlotter-Gen is a super-script to build OpenPlotter images and NOOBS files from scratch. You will be able to create OpenPlotter flavors easily.
Helping us

We have developed an application openplotter-myapp which is a template with the basic structure of an OpenPlotter app with comments to make easier developing your own app or help us with any pending app. If you have python skills and want to help, contact us to coordinate.

Please reply to this post your questions, feature requests and bug reports...

  Openplotter 2 with touchscreen
Posted by: mgrouch - 09-14-2019, 12:43 AM - Forum: General discussion - No Replies


I’m not sure if that general issue with touchscreen support in Linux or OpenCPN issue
on Linux. I can’t make openplotter even decently usable with a touchscreen.
No 2 finger zoom. I took same screen (it supports multitouch, argonaut m7 gen2)
and it worked with windows 10. I could zoom with 2 fingers, etc. 
with raspberry pi 4 and openplotter 2 I can’t even measure distance between points
It keeps adding more and more points with no way to remove them. 
I guess because there is no double click emulation?
Anything user input related from a touch screen is mostly unusable. 
I can’t use search plugin to search a chart because there is no way to type. 
Should be there a on-screen keyboard?
View only functions seem work. But the point of having a touch screen 
should be ability to do some user interactions. For me all I could do on a touch screen is move 
mouse pointer around and do right clicks. 
What am I missing in set up? Or I should just look into windows 10
with opencpn on it for a cockpit touchscreen?


  charts for kentucky lake?
Posted by: saltylanguage - 09-13-2019, 03:38 PM - Forum: General discussion - Replies (2)

Hi, I just got openplotter working in my boat but cannot find charts for Kentucky lake (where I am at right now) or the surrounding rivers. I am making my way down to Mobile bay and would like charts for the trip. Is there any way to load them or did I miss them? Thanks Robert

  opencpn pypilot plugin, autopilot_route via git for OP2?
Posted by: rastam4n - 09-12-2019, 05:47 PM - Forum: General discussion - Replies (2)

I tried to update the plugin for opencpn  and install autopilot_route on my RPi4... got some errors, guessing its not ready for that?

maybe there is a separate git for that?

  Mast-Top Camera?
Posted by: sjgharib - 09-12-2019, 12:08 PM - Forum: General discussion - Replies (4)

An idea struck me:

When anchored out, depending on visibility conditions, a good practice is to scan the horizon periodically based on how far you can see.

I know you could turn on your radar (if you have it), but I was thinking with the latest high res digital camera technology and image stitching software, it would be relatively easy to mount a number of small cameras on the mast-top and then be able to take periodic pictures (or a live video feed).

Would that be of interest to people, provided the hardware is lightweight and low profile?
