Can you show your schematic? There shouldn't be anything connected to A5. And your oscilloscope screenshot doesn't even show a full bit. Can you set it to 10µs per division...

The library assumes that your device is a so called *bus-powered USB device*, i.e. it only gets power via USB. If so, your described behavior will not occur because the...

I guess it would be helpful to mention it. But I don't think there is a "standard" software. As far as I can tell, there are multiple different software versions...

The pre-packaged fonts should be used if: - PDF output is generated - The bill's character set is either EXTENDED_LATIN or FULL_UNICODE (see https://javadoc.io/static/net.codecrete.qrbill/qrbill-generator/3.3.1/net/codecrete/qrbill/generator/Bill.html#setCharacterSet(net.codecrete.qrbill.generator.SPSCharacterSet) I do not recommend using these...

The error message sounds as if you are using the `Codecrete.SwissQRBill.Core` instead of `Codecrete.SwissQRBill.Generator`. The former one does not include PNG generation. If this is not the case, then please...

Your case sound familiar. We've seen it before. If `Codecrete.SwissQRBill.Windows` is indirectly referenced (e.g. Application -> Class Library Project -> SwissQRBill package), then Visual Studio seems to optimize `Codecrete.SwissQRBill.Generator` or...

I've taken the case to extend the README. See https://github.com/manuelbl/SwissQRBill.NET?tab=readme-ov-file#png-generation. The better code to include might be `CanvasCreator.Register(new PNGCanvasFactory());`. It works with both `Codecrete.SwissQRBill.Generator` or `Codecrete.SwissQRBill.Windows`.

Thanks a lot for your PR. I'll have a closer look at it. So far, the library has been 1 to 1 translation of https://github.com/nayuki/QR-Code-generator. This would be a deviation....

Thanks you very much for your contribution. Given the small size of the code and the independence from any additional libraries, it might in fact be a good addition. I'll...

On macOS, this library relies on the operating system to get the serial number. So if macOS does not provide it, the library won't either. Does macOS (as seen in...
