Virtually all goods sold in retail have 1-D codes carrying electronics product identification codes (EPC) according to various standards or 2-D codes formatted in form of QR codes typically used for marketing purposes.
Barcode scanners all use a laser diode to illuminate the code, and a laser-diode detector, or a CMOS camera module to read the data. These readers can be fixed at the point-of-sale or hand-held – either tethered or battery operated.
We offer 32-bit STM32L4/F4 microcontrollers capable of efficiently processing the optical signal data to quickly decode EPC barcodes or tags while still being able to control all the unit’s other peripherals together with efficient power management solutions.
