Rfid Reader- Pic
hello-
i wish to connect a RFID reader to a PIC and then to a LCD so that i can display the TAG IDs.
However i am completly stumped when it comes to connecting this set-up ( as i am reasonibly new to the world of electronics) - the reader which i currently have is a core- 12

do you know if this is possible?
do i require additional hardware?
how can this be done?
help with any of these would be gratefuly appreciated thank you

Yes, the PIC can do it. Yes, PBP will be very useful.Originally Posted by cleas001
Yes, if you are completely stumped as to how to connect this setup and you are new to the world of electronics, you are most definetely in over your head. Quite frankly, this is a simple project, for an experienced person anyways.
But, don't let that rant stop you in the least.
What kind of equipment do you have, if any? Programmer? Dev Board? Compiler, etc?
What experience, if any, do you have, programming PICs, or any MCU for that matter?
Made any blinky LEDs or anything like that?

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.

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=
