Summary of PIC16F84 BARCODE READER CIRCUIT
This article describes a PIC16F84-based barcode reader prototype using the NW-7 standard. The system scans 7-bit codes containing 0–9, $, :, /, +, and letters A–D, utilizing three black and white bars per character with start/stop markers.
Parts used in the PIC16F84 Barcode Reader:
- NW-7 standard barcode reader
- PIC16F84 microcontroller
- Hand scan prototype system
- Circuit schematic components
- PIC assembly source code
