barcodes, filtering a number signal with a gate and delay.

January 24, 2013 | 2:31 pm

I’ve created a patch that uses a barcode scanner to trigger audio files, But I have a problem with the signal path.

The number in the forth box (the second number box) outputs a number between 48-57, which is what I want. But before the final number is reached several other numbers flash up, for a fraction of a second before. I want to send the signal through a delay/gate so that the only final number reaches the the number box just before the signal is sent out to the audio triggers.

I realise I have not worded this very well, but any input would very much be appreciated!

Hey, I like your idea. I’m looking for a barcode reader app that would scan the barcode on a ready meal and then play a pre-recorded video of the cooking instructions. And I am doing this because I want to help someone with a learning dissability. And I think your project will make it better.

luluuu,
thank you for your sharing:

this is a barcode reader guide, and looks good.
and I also find a barcode scanner there, it contains more info, including barcode reader guide.

Hi, Clintonzz.
I am using another manual barcode SDK in stead of the one you mentioned above. I wonder do you have some recommendation about the ones which can be customized by users according to our own favors? Thanks in advance.
