Re: Touch screen for NanoDLP

Would someone more knowledgeable care to look at my mods to the nextion 2.4" touchscreen? 

https://github.com/sgraber/TouchScreen-For-NanoDLP

Based on what I can tell, I have modified it appropriately, but none of the 4 buttons I placed in the home.js file work.  They show up on the Nextion screen and I can press them, but they don't call the proper URLs, which are /button/press/0 and /button/press/1.  Thank you!!!

Re: Touch screen for NanoDLP

Hello, it's not the name software listen to but the id of the button. So you have to change

this.addListener("click_c0", () => this.nanoDLP.command("/button/press/0"));
this.addListener("click_c1", () => this.nanoDLP.command("/button/press/1"));
this.addListener("click_c2", () => this.nanoDLP.command("/printer/off"));
this.addListener("click_c3", () => this.nanoDLP.command("printer/restart"));

To

this.addListener("click_b4", () => this.nanoDLP.command("/button/press/0"));
this.addListener("click_b5", () => this.nanoDLP.command("/button/press/1"));
this.addListener("click_b6", () => this.nanoDLP.command("/printer/off"));
this.addListener("click_b7", () => this.nanoDLP.command("/printer/restart"));

Re: Touch screen for NanoDLP

juliendelnatte: 

Take a look at "2.4_LittleRP.HMI", which is the one I modified for my LittleRP resin printer.  If you look at home.js, you will see four new buttons with objnames c0, c1, c2, and c3. 

I then reference them as I did in the following two files:

https://github.com/sgraber/TouchScreen- … es/home.js

https://github.com/sgraber/TouchScreen- … es/home.js

The /button/press/0 event calls an M8 gcode which disables my stepper.  The /button/press/1 event calls M9 gcode which enables the stepper.  Pressing either of those buttons do nothing to my stepper motor at all.  If I log into http://localhost/ I can click the button on the webpage that calls these two urls and they work.

I'm at a loss why it's not working.

Re: Touch screen for NanoDLP

It's what I said, I looked at your HMI and your code. It's not the name of the component is sent to the program but the ID. and the event is "click_b"+id. So I sent you the fix

Oh my goodness.  Is that it?  It uses the id instead of objname?   /me smacks his head

Re: Touch screen for NanoDLP

The output.log in Nextion folder says:
error opening port  /dev/ttyAMA0 retry in 2 seconds
The cmdline.txt reads as follows:
dwc_otg.lpm_enable=0 console=tty1 root=PARTUUID=20bc60e1-02 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait

I'm stuck with the same problem on a RPi2B and a Nextion Basic 3.5". I'm running v2. I think I tried all solution I saw online, but I can't find the issue.

I initially thought it was a permission/serial port issue, but after some checking I just realized  it's should not.

/home/pi/nextion/output.log:

{ nextion: { port: '/dev/ttyAMA0', sleep: 30 },
  pushbullet: { apiKey: null } } { apiKey: null }
connect to port /dev/ttyAMA0
list [ { comName: '/dev/ttyAMA0',
    manufacturer: undefined,
    serialNumber: undefined,
    pnpId: undefined,
    vendorId: undefined,
    productId: undefined } ]
connected

On startup I have a root process running "node /home/pi/nextion/bin/index.js". Not sure if it should be root. I tested as user pi running the same process from command line and got the same output [connected].

Any hints? Is there any command I can try to send through minicom to completely exclude any  communication-related problem? Like the command display is expecting to move to the main screen.

Re: Touch screen for NanoDLP

Thanks you all for information,

I have a 5" display and it's now working, but with a lot of bugs, such us:
wrong image size on preview
when a printing start from browser it don't display the current printing process
etc...

have some one fixed the bugs?
I'm not expert but maybe I can fix by myself, can someone show me where I can do this?

thanks a lot

I'm stuck with the same problem on a RPi2B and a Nextion Basic 3.5". I'm running v2. I think I tried all solution I saw online, but I can't find the issue.

I initially thought it was a permission/serial port issue, but after some checking I just realized  it's should not.

I did find the problem. I just did not realized you need to change the url in config.json when using non-standard web interface port. 

{
  "url":"http://localhost",
  ....

to

{
  "url":"http://localhost:PORT",
  ...

where PORT equals to your port number.
I am writing back in case someone else could find the same problem.
It might be nice to add this info in the README for other users, just in case. Or otherwise any kind of debug info when program cannot connect to the interface. I had been messing around a lot with the serial settings, thinking it was a pi serial configuration problem. Killing node process and running it from console with

DEBUG=* node /home/pi/nextion/bin/index.js

I could notice that program hang after successfully sending the first commands (sleep=0,bkcmd=3,etc) but there was no debug info like "cannot connect to url". It might be helpful to debug configuration.
PS: Thanks again for the great work!
