Responding to: Frank Jin's previous message
How many 8051 core CPUs will you use in your POS project?

I'd start with the below with an eye on possibly reducing by one or two. A handful of sub $1 LPCs are a lot easier to handle that a $10 processor trying to do it all


one for
barcode scanning

one for
price lookup

one for
accumulate total bill
control the cash drawer
calculate change from tendered amount


one for
credit card authorisation

one for
receipt printing
displays for both customer & checkout operator

one for
interface to weighing scale

one for
calculate price for weighed goods

What kind of communication protocols are you planning to use? IIC

Erik
