barcode length

Hi STeven

I was trying out the barcode module, printing codes and reading them. I find that two digit codes are not read, while 3 and up, are?

So I can easily read '516', but '56' shows nothing.
Codes tried were Code 39 and Code 128.

Are two digit barcodes, as a rule, not allowed?

I assume you mean something like the attached?

If so, the code for those is slightly different as there is a 01 in the middle. If you can post examples we can probably adapt the EAN or UPC to accept that format. Shouldn't be much different than the current format.

Hi STeven

Sorry, I thought I had attached files. The thing is, I thought a two digit code would be a lot shorter than a three, and easier for the camera to see from a distance, but they are of similar length in 'Code 39'

So not to worry, I will use three digits. I was only wondering if I was doing something wrong, or what the reason is for the three digit minimum.

Regards
Roland
