yes ive got basic knowledge of programming and ive got all that equuipment avialiable should i need it - im just confued by the data sheet supplied with the reader - as to which pins i would need to connect the PIC towould these be the 2 free data lines?

Looks like pin 9 (ASCII out, TTL) to me, just like the datasheet says.Originally Posted by cleas001

The core-12 reader has a serial output at TTL level. So it is a piece of cake to connect and start getting data into your PIC. PBP supports Serial protocol (RS-232) either in software or in hardware. I recommend the second using Hserin command if your PIC has a UART. Note that you need to put a MAX232 chip. The core-12 has inside it an inverter. If you are going to use a PIC with no UART, then use Serin2 command with invert parameters.
Every time you cross a card over the reader, a stream of ascii data are output of the core-12. Have your PIC read the stream into an array and you are done.
More about syntax, examples etc, put the words that you just read into the search of this forum. You will find everything on Serial ports, LCD, ASCII, and us here when you write your code that obviously is not going to run first time! 8-)

hello
you mention about the serial port? is this to conect to computer? - i do not wish to conect my device to a computer- is there a way in which the PIC an process the information to display on the LCD - withouht having to go through a serial port?
the type of LCD i mean is one like this: http://www.maplin.co.uk/Module.aspx?...6389&criteria=

These 2 statements seem to conflict.
How much MCU programming have you done? Not Windows, not Visual Basic, actual MCU programming, at the binary/hex level?
Reason I ask is that if you are somewhat knowledgable in this area, then you would know that a fair share of PICs out there have built in UART specifically for external serial access, and those that don't are able to obtain external serial access by means of software emulation through PicBasicPro (or other compilers out there).

hello thanks for all the help so far
in answer to your question i have so far been doing my programming in mplab - so i knowledge of the programming methods and languages in that.

I suggest to read again the answers especially #5 word by word. It is explained that PIC can do serial rs-232 either in hrdware or in software. To succeed in this project you have to read a lot the data sheets of the pic you are going to use and the manual of the PBP that obviously you have not so far. Please, please search and read. All info's are in front of you. It is easy project, you have all the resources, so do it!
If your code is not working we are here to check it out. But don't expect to write it for you... Unless you pay for it! $-)
