Enhancing Barcode Scanner Design
Advantages of an Integrated Solution Based on a 32-bit MicrocontrollerBarcode scanners have become such a ubiquitous technology that it is easy to take the complexity of their underlying designs for granted. Barcode scanners require multiple discrete integrated circuits and an array of passive and active circuitry to provide the functionality and reliability that end users have come to expect. Many barcode scanners generally use an optical sensor, such as a charge-coupled device (CCD), which outputs an analog representation of what is “visible” to the sensor to an analog-to-digital
