Question Forward I2C signals to server K and OpenCPN
Posted by: Leigh - 10-02-2017, 07:17 AM - Forum: How do I...? - Replies (7)

Hi,

I did attach some questions to old threads on similar subjects but thought best to start new thread

I have a RPi3 with Sense hat (I already have it and will distance from RPi via a ribbon cable, to be kept down below and use VNC to Android tablet / phones)

I have the I2C signals in Openplotter - I can see them in 'Inspect'

But I have no idea how to get them to OpenCPN (I add them to Dash but empty) and server K

Do I have to 'forward' them to IMEA or something?

As you can see, I am a begginner in all of this

However, I do have some background in sensors etc even if it isn't my field, and can follow instructions or leads and learn Smile

Effectively, I have the signals, but cant use them

I have 0.8 and 0.10 on two different SD cards, but am using 0.8 as this has 'Inspect' and at least the heading has been passed to OpenCPN as it's value is displayed in the Dash and the boat position marker rotates as the sense hat does
(so perhaps I could use how heading has been done as a 'template' for the other signals to follow - if I knew where to look)

Thanks for you patience, hopefully

Leigh


  Version of OP documentation
Posted by: SkipperEarly - 10-01-2017, 03:38 AM - Forum: Documentation - Replies (1)

I keep looking at https://www.gitbook.com/book/sailoog/ope...on/details for the latest documentation.
It always states 0.9.0 as version on the bottom.

I suggest to add a version control line giving info such as 
- current version
- last update date

Thanks for attention


  OP dialog not remembered
Posted by: SkipperEarly - 10-01-2017, 03:25 AM - Forum: Feature Requests - Replies (1)

I noticed that when the user resizes the op dialog or the columnes that these positions get forgotten after closing.

Would be nice to have them remembered.


Question Scan Charts & Calibrate into OpenCPN ?
Posted by: Leigh - 09-30-2017, 06:45 PM - Forum: How do I...? - Replies (7)

Hi,

Love OP, but there are (I can find) no charts for OpenCPN for Lisbon and the R. Tejo (Targus) where I sail

What I have done for Pathaway is to scan my paper charts and then calibrate them using the tools on their website.

Is there a nice simple step by step for this for OpenCPN?
If not, some hints so that I can make one?

I much prefer Linux, but can also boot into Windows 10

Thanks

Leigh

  [SOLVED] Openplotter won't start after upgrade
Posted by: abarrow - 09-27-2017, 11:37 PM - Forum: Bug Reports - Replies (5)

I just upgraded my OP version 12 system after being away for a couple of months. It upgraded to version 15.

Now, Openplotter won't start. 

When I try running openplotter in a terminal window, I get this:

Code:
pi@openplotter:~ $ openplotter
Traceback (most recent call last):
 File "/home/pi/.config/openplotter/openplotter", line 3517, in <module>
   MainFrame().Show()
 File "/home/pi/.config/openplotter/openplotter", line 250, in __init__
   self.read_i2c()
 File "/home/pi/.config/openplotter/openplotter", line 1881, in read_i2c
   self.list_i2c.Append([str(c), name, address, magn_list[c], iii[0], str(iii[1]), str(iii[2])])
UnboundLocalError: local variable 'magn_list' referenced before assignment

title says it all.
i don't understand the value setting and convert in the SPI tab..???
could someone explain please..

  Time buffer in actions
Posted by: Luckbert - 09-26-2017, 05:21 AM - Forum: How do I...? - Replies (3)

Hello everybody,
I think I'm standing on the hose.
I would like to perform an action only if a trigger triggers a certain time.

Eg: A float switch is connected to GPIO. When he triggers, he shows a message "Swimmer front".
Now it could however be that the float switch triggered by vibrations without water.
My idea: Show only a message if the trigger (float switch) min 2 sec.

Greetings Jürgen


in German:
Hallo zusammen, 
Ich glaub ich stehe gerade auf dem Schlauch. 
Ich möchte eine Aktion nur ausführen wenn ein Auslöser eine bestimmte Zeit triggert. 

Z.B.: Ein Schwimmerschalter ist mit GPIO verbunden. Wenn er triggert zeigt er eine Meldung " Schwimmer vorn". 
Jetzt könnte es aber sein das der Schwimmerschalter durch Vibrationen ohne Wasser auslöst. 
Meine Idee: Zeige erst eine Meldung wenn der Trigger (Schwimmerschalter) min 2 sek besteht.

Grüße Jürgen


  Openplotter and Navigatrix
Posted by: topodom - 09-24-2017, 05:17 PM - Forum: General discussion - Replies (3)

Hi everyone,


First of all, congratulation to the team for the accomplished worked.
I ll install openplotter on my raspberry soon. In an other hand navigatrix is good also with very interrestinggs softwares. what is the link between the two projects ? is it sheduled to merge the both projects ? Or should i install the software of navigatrix on my raspberry by myself ?
Regards

got enough parts to start

[img][Image: th_IMG_20170922_055254.jpg][/img]

soldered in a 16 pin socket and wired up  mcp3008 and screw terminals.
[img][Image: th_IMG_20170922_055405.jpg][/img]

back side with 4 of the analog pins to the terminals. and ground plane
[img][Image: th_IMG_20170922_062702.jpg][/img]
   
MCP3008 VDD to Raspberry Pi 3.3V
MCP3008 VREF to Raspberry Pi 3.3V
MCP3008 AGND to Raspberry Pi GND
MCP3008 DGND to Raspberry Pi GND
MCP3008 CLK to Raspberry Pi SCLK
MCP3008 DOUT to Raspberry Pi MISO
MCP3008 DIN to Raspberry Pi MOSI
MCP3008 CS/SHDN to Raspberry Pi CE0

mpu they sent the wrong one again package said 9255 but its 9250. thats twice i got the wrong one sent to me Sad
[img][Image: th_IMG_20170922_064855.jpg][/img]

the bmp280's pins lined up with with the imu so i soldered them together.

[img][Image: th_IMG_20170922_171814.jpg][/img]

all data coming thru except humidity.

   

i hooked up a float switch to gpio 18 and a voltage sensor to spi mcp3008 to test all seem to be working

   


antenna cable and handheld VHF antenna.
[img][Image: th_IMG_20170922_062359.jpg][/img]

i ran into a problem with the mcp 3008  i need to pull the screw shield and check again with the multimeter.. SK is showing data but it should be 0 ..
i have four pins that i am testing with  1,4,5,7  pin 7 is the only one with data going to it "battery voltage sensor"and its wrong. when it is passed to the function in nodered to do the math to volts it shows 18v multimeter says 12.1v at the battery. when i checked the pins and ground there is a voltage of up to 2+ volts there should be 0 it's input not output.

i pulled the board tested all my connections several times everything is as it should be no shorts or grounding, the pins all connected to the correct places.???????

i dont understand the value setting in the SPI tab..??? maybe that's where the problem is..i cant seem to zero out raw data, it gives false data even with nothing going to it..
i had it working perfect with an arduino on the usb & firmata..
so if i want to go forward i guess ill go back to arduino analog for now...

   

that's it for now i will edit this post as i get more built..
