Barcode scanning

[tama]

Thanks, I've sorted out the screens. Now I have another problem. There is a text.csv on the flash drive. It is necessary to enter data from it into FIREBASE, I designate the data as //text.csv, but the program does not see them.

There is a text.csv on the flash drive

Do you refer to a USB Flash Drive?

You will need to use this @Taifun extension »

But this has nothing more to do with 'barcode scanning'...

Error 908. Android 14.
I want to read the tovar.csv file in the DOWNLOAD directory

[TIMAI2]

If your file tovar.csv, is not owned/created by your app, then you will need to use the SAF extension to read your file.

@TIMAI2 Thank you. I'm going to look for him.

Select list item: Attempt to get item number 2 of a list of length 1: ["No content provider: /Download/tovar.csv"]

the contents of tovar.csv

maybe SAF1 doesn't work with the CSV file

[TIMAI2]

You have to access the file either with the filePicker or with the SAF Open Document block, then return the contenturi to the SAF ReadFromFile block. You cannot use normal filepaths.

Consider uploading your spreadsheet to Google Sheets, and downloading it from there using the Spreadsheet component.

That would avoid all file permission hassles.

[Hello...Help me solve the issues: 1. A person pronounces a word and it is written in TINYDB, I decided it like this]

2.How can I play this recording from tinydb?
I would like the solution to be free

[TIMAI2]

1. Speechrecogniser Get text
2. When you have the text in the gotText event
   • check if the text is contained in the tinydb text
   • handles the output based upon whether this is true/false

The components cannot hear what is being played back in the device's internal audio.

How do you create a voice assistant?

Here's a minimal single purpose one:

This is a sample app you can study for speech recognition.

In your blocks you made these mistakes:

You expect a speech result immediately

You try to store a component in TinyDB

You didn't look in the component block pallette for the block with the speech recognition result

You didn't use the speech recognition event block

Thank you @ABG and @TIMAI2 . and how to make the car obey exactly the commands of the OWNER and therefore it is necessary to record the VOICE of the command of the OWNER of the car in TINYDB and then compare whose voice and if equal, the car turns on

That sounds like a job for AI.
