example with HMI and python code

[javed222]

Hello Can you provide a small example using this library in projects with text, buttons etc? Thanks

[yozik04]

For buttons you will use TOUCH event. That will give you required data to figure out what button was pressed. Text update commands are also in the code example on the repos's main page.

Thank you very much!

Please, Can you create a TOUCH event on the code example on the repos's main page?

Would be usefully for me!

Thanks for your response

Thank you yozik04!! Was very useful, you new example!! Only have one question more All is right if the text are in one page, But If have two pages? The client for set text, didn’t had a page_id definition await client.set('field1.txt', val) Please inform me how I must to do Thanks

[yozik04]

Please look up in nextion protocol. Probably “page-id.component-id” also works

[javed222]

Thanks

I have two pages: “tablero” and “settings” and this code:

await client.set('tablero.temp.txt', Xtemp) await client.set('tablero.hume.txt', Xtemp) await client.set('tablero.rocio.txt', Xdp)

If run the client, with nextion display on page “tablero” all is right, but if change to page “settings” on nextion, to settings the following error occur: nextion.exceptions.CommandFailed: Variable name invalid for command: tablero.temp.txt="23.0"

I think that the problem is set text on two o more pages

[yozik04]

Firstly try setting these values in emulator. This will help you find the right path.
