  Need Help hooking up transducer (DST800)
Posted by: terestron - 02-18-2020, 06:46 PM - Forum: General discussion - Replies (5)

I have a DST800 Triducer (NMEA 0183) and I am trying to hook it up to my OP V2.  I bought a USB to RS422 adapter.  I hooked up the wires correctly (R+ and R-).  The Recieve LED flashes RED and I have 13V to Transducer.  OP sees it in the serial tab.  I connected it to serial K via the AUTO at 38400 Baud.  In OPEN CPN i added it under connections. But it added it as 4800 baud.  but I am getting no response to temp, depth, or speed.

BTW, I am doing this all in my office before I install.  It is a RPI V3b+, Serial GPS works fine.

I not well versed in this.  I must be missing something.  

Can any one help?

  mpu broken 3 times?
Posted by: sideluxe - 02-18-2020, 10:47 AM - Forum: General discussion - Replies (5)

Hi threre, 

after a long time without getting the project forward i wanted to update to the newest build and software.
Last year the pypilot started working slowly but had some space for improvement on my boat.

2 things i dont understand actually are

1.  after updating via git everything seems to work but after a reboot my display hangs on pypiolt 0.12 and the keypad is not working using the autopilot via web control or plugin is still possble

2.  yesterday all my mpus stopped working, heading is still displayed, but when turning the heading changes to a new direction and then goes back to the old heading before turning.
i tried 3 different mpu as well as pypilot 0.9, 0.12, 0.15 all the same
python has gyro and heading values but heading changes as above when tunring the mpu.

i dont know where to search next, because i dont think all mpus are dead. could this be a defective pi zero too?

Any suggestions would be fine.

Thank you all

  Pypilot on motorboat
Posted by: hakahl - 02-18-2020, 05:47 AM - Forum: General discussion - Replies (1)

Marine newbie here.

Planning to buy a boat and as a open source/computer nerd I quickly found Openplotter and Pypilot. Pypilot seems to be developed on a/for sailboats and most (all?) installations are on sailboats. Are there any motorboat users out there?  How is it working? I guess it is way more complicated to calculate courses for a sailboat. Would that make the autopilot too complex for a small (~20 ft) motorboat?

  Moitessier 2.0.7 stable
Posted by: SkipperEarly - 02-17-2020, 08:27 AM - Forum: Feature Requests - Replies (3)

I like the quick check for temperature and pressure but miss the same for gps.

The LED is only start blinking when a fix has been achieved but it would be nice to provide some gps-check which shows the satellites in view etc. and give some warning if the antenna strength is not sufficient.

PS: Btw the pressure-check does not show since the last update to 2.0.7 - before it did

  Open a message window (Pop-up)
Posted by: Luckbert - 02-16-2020, 02:17 PM - Forum: Node Red - Replies (5)

Hello, everybody, 
I have installed several float switches. In old OP versions there was a tab called "Actions". 
With that everything was very simple. 
Now it seems to me that the solution is in Node-Red.
I want a window to open and a sound to be played when the float is released. 
The sound is not the problem, but what do I have to do to open a message window.
Greetings Jürgen

  MOB-Button in node-red
Posted by: Luckbert - 02-16-2020, 02:07 PM - Forum: Node Red - No Replies

Hello, everybody, 
I would like to realize the following. I want to connect a push button to GPIO. When pressing this button a MOB marker or simple marker should be set in OpenCPN. 
There is the possibility to solve this with a key combination. Unfortunately I failed to trigger a key combination in nodered. 
I have solved it via 


tried. Unfortunately without success. Anybody got any ideas?

Greetings Jürgen

  tinypilot on RPI3
Posted by: Ola_H - 02-16-2020, 07:36 AM - Forum: General discussion - Replies (8)


I try to run the tiny pilot image on a RPI3B. Doesn't work, doesn't start. Files on SD seems readable and so on. 
Whats wrong? Any modifications that needs to be made before running on a RPI3B?

best wishes

  Adding device name to Serial list
Posted by: plotter23523 - 02-15-2020, 01:25 PM - Forum: Feature Requests - No Replies


A feature request for the Serial application.

When running 'sudo lsusb' in the terminal, you'll see a list of devices, together with the name.

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 046d:c05b Logitech, Inc. M-U0004 810-001317 [B110 Optical USB Mouse]
Bus 001 Device 003: ID 1546:01a7 U-Blox AG [u-blox 7]
Bus 001 Device 002: ID 2109:3431 VIA Labs, Inc. Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

As we can connect multiple USB devices, like AIS and GPS, wouldn't it be possible to show also the name, instead of just the IDs?

It would make it so much easier to select the correct device.

Best regards,
