Barcode¶

Overview¶

This chapter explains how to operate the barcode reader function using AsReaderBarcodeDevice.
You can connect to the device, start and stop reading, and receive reading results.

Supported Devices¶

ASX-510R, ASX-520R, ASR-010D, ASR-020D,
ASR-022D, ASR-0230D, ASR-0231D, ASR-0240D,
ASR-M24D, ASR-025S

Used Classes and Protocols¶

List of Used Classes and Protocols¶
Name	Type	Description
`AsReaderBarcodeDevice`	Class	Main class for controlling the barcode reader
`AsreaderBarcodeDeviceDelegate`	Protocol	Delegate used to receive reading results and others

Initialization and Connection¶

AsReaderBarcodeDevice *device = [AsReaderBarcodeDevice sharedInstance];
device.delegateDevice = self;

delegateBarcode: Set this to receive barcode reading events.

Start and Stop Reading¶

[device startScan:0 readUntilInSec:0];   // Start reading
[device stopScan];                       // Stop reading

Receiving Reading Results¶

- (void)receivedBarcodeData:(NSData *)data {
    NSLog(@"Read barcode: %@", data);
}

Implement this as a method of the AsreaderBarcodeDeviceDelegate protocol.
