Barcode decoding for a dumb wand scanner

Help Anyone Please

I need to integrate a dumb wand through C language, with an 8051 microcontroller to display the price of barcodes that are scanned. Any ideas on code and any circuitry needed?

Many thanks

that depend on you wand. Some of them are either serial or PS/2.
Serial will require a MAX 232 serial interface, PS/2 will require some kind of clocking signal from the microprocessor.
To show the price, you will need a serial or parallel LCD module, parallel use to be cheaper (about $20), serial more expensive (about $50).

I have searched for this code MS119 without look. I have no idea how you will guess the signal encoding of the wand.

MSH 119 from opticon what i really need it for is a code written in C to allow integartion with an 8051 to allow scanned items price to be displayed and keep a running total cheers would greatly appreciate it

Well, sounds like you need to hire a microcontroller developer. Maybe rentacoder.com

yeah i have red +5v green TTL and screen GND.. that not a bother but im in need of code to see when code is scanned what price is produced i.e £1.99 e.t.c stored in my database (internal in 8051)... i only have to have a small ammount of products to show an understanding not a whizz kid
cheers for the help so far
