Description
Experience Level: Expert
I am looking to hire someone to design a circuit for me and be able to just provide the circuit schematics as well as code needed for the IC's involved. What I need to do is design a circuit that can communicate via a serial DB9 connector with a slot machine. It would need to be able to read what is coming in on the serial cable as well as transmit responses via the cable. It would also involve a database that would need to be stored on some kind of non-volatile memory that will be able to be read and written to. I would like this to be a SIMM or DIMM chip like a computer would use for RAM with a battery backup so it is not volatile. The basic program would need to be able to accept and interpret a barcode transmitted to the circuit, compare that barcode to the database, and if the barcode is in the database it would return the value associated with this barcode via the serial cable. It would also need to be able to accept a new barcode and value to write to the database. I am looking for this to be independent of a computer, so it would need a microprocessor to complete the task. I currently have software written in c# that does what I want the circuit to do, so that could be used to convert to C or another language that could be compiled to the IC.
