LCD Display

[fsnew]

Hi, you are very kind. You are encouraging me in proceeding on my attempts. So, if i'I am right, I would not need an LCD or hat device to operate a keypad and I am trying to check through the steps you kindly listed above. However I have to solve some problems related to the lack of connection to the pypilot server in browser remote mode. I would report below some outputs in order to check which are my essential issues.
ps. I have installed pypilot as a plugin through Openplotter settings and not from github. Is it a fundamental difference?
Many thanks for your kind assistance. 

No worries, I like it when people don't give up. You are right in saying that you can operate a keypad without and LCD or hat device. If you have installed pypilot through openplotter, though, you are likely to have a very old version *). Better leave the 'plugin' in openplotter, but install a fresh pypilot from github over it by following the steps given here. Read the workbook over again; it was intended to take one by the hand.

When you see this :

Code:

failed to run web server: [Errno 98] Address already in use: ('0.0.0.0', 33333)

it means that pypilot_hat is already running. Apart from that, I cannot see major issues.

*) Openplotter provides a(n older) version of pypilot, but adds a few wrapper scripts to it, so pypilot adopts the openplotter look and feel. Pypilot, though, is developed at a much faster pace than the openplotter wrappers are kept up, so the two might be a bit out of sync.

Hi! Good news for me. Following your detailed instructions and after a lot of attempts I have been able to do my pypilot arrangment working. So now,  after having installed pypilot git on a combined raspi+openplotter software I am able:

1) To control the pypilot through localhost 33333 by a keypad switch;
2) To launch pypilot on the terminal by pypilot_hat service;
3) to open pypilot desk by the pypilot_control service on the terminal and localhost 8080;
4) On OpenCPN  I have been able to add a GPS -Usb  device that works as it should.

 I am proceeding in my project to add a  Nokia or jlx12864 LCD display recently bought in order to use the pypilot base code by Sean. 
My question is:

a) As now I can launch pypilot on terminal ( and it works ) what happens if I add the pypilot Openplotter and OpenCPN plugins? Could I be sure that the pypilot function and relative control desk ( both Openplotter and OpenCPN) would work without launching pypilot_hat on the terminal?

b) Is it possible on the start of my Raspberry to have quickly available, without any other command , the OpenCPN output on a LCD display interfaced through the micro HDMI port to the RASPI? My aim is to control the autopilot through an external keypad only and to see the navigation status over the OpenCPN chartplotter at the start of the Raspberry without the necessity to open by hands any windows on the Raspberry. 

I am very grateful for helping me.
Best regards
