TinyWeb Console for 320x240 LCD Display

[aperoap]

hello, i use your IMG v1pi on pi 3+. Is there a way to install TinyWeb Console for 320x240 LCD Display?

[jeffeb3]

Yes. There are two parts to the problem.

1. installing the LCD, installing the x server, and Configuring the pi to show it's display there.
2. Installing the pendant code, configuring cnc.js to run it, and configuring a web browser to show it.

Have you already tried 1? Is there a good screen and instructions you followed?

[aperoap]

I can not find the installation folder and cnc.js :)

[jeffeb3]

npm installed it in /usr/local/lib/node_modules/cncjs

If you want to add the -m option to add the pendant module, the startup command is in /etc/default/cncjs

[jeffeb3]

The default content in the /etc/default file is from here: https://github.com/jeffeb3/v1pi/blob/master/src/modules/cncjs/filesystem/root/etc/default/cncjs

And the command that installed cnc.js is here: https://github.com/jeffeb3/v1pi/blob/master/src/modules/cncjs/start_chroot_script#L24

If it works for you, I wouldn't mind trying it myself, and maybe including it in the next (TBD) version of the image. I'm assuming it's pretty small, so it's not too terrible to run all the time. I would just add the commands for installing the pendant code after the npm command in the start_chroot_script.

the server is started correctly, but the page gives an error.

do you have an idea what this may be?

how can i add the -m option in
/etc/default/cncjs
?

[jeffeb3]

You can add the -m to DAEMON_ARGS.

It should be port 5080 when that comes up.
