Barcode Emulation

Enables ordinary LEDs to transmit barcode data – The Barcode Emulation reference design allows an ordinary LED to transmit barcode data. The LED is driven such that it transmits pulses that can be read by a checkout scanner.

Applications processor connectivity – The barcode reference emulator is designed to connect to an applications processor and offload these functions commonly found in smart phones and other mobile products via I2C or SPI.

Low power design that maximizes battery life – The design is based on the iCE40 device families, which have been designed from the ground up for low power, maximizing battery life and minimizing power consumption.
