Re: Touch screen for NanoDLP

My Nextion was connected and talking to the Pi but now it's not.
The only thing changed was unplugging the Logitech USB keyboard receiver.

I upgraded to the newer version but it did not change anything.

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

Any clues guys?

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.
