being a Geek in college I must invent a better whiteboard .
I really want to use a IPAD but there is now way Ill stick a 600$ device out of my room .
so I am using the parallax Serial LCD module to display stuff out side of my room
and here is the kicker I can store a TON of pre made messages In the BS2 and with the needed button latch a message . Eg ( Grub time ) ( sleeping ) ( come on in !) so on .
or just default to a list of my contact info .
There was not a schematic as its just 3 wires on a BOE board .

Its no iPad, but you could move up to the uOLED-128-G1 for not too much money - http://www.parallax.com/Store/Accessories/Displays/tabid/159/CategoryID/34/List/0/SortField/0/Level/a/ProductID/452/Default.aspx
You could display your avatar and other cool color graphics too!
One day you will be older and have kids - You will show them you latest creation - they will look and you (like my daughter does) and say, "Dad, your such a nerd..." OUCH!
I may have to add a TEMP reading one of thease days .
Esp considering the weather here ..

EDIT well in true fashon I did my first RCTIME to LCD project
and a
Video
so far is super simple but ill admit getting that dev board was just what I needed to get back to building stuff .
Nice job that you did and it says geek all the way. Now, all you have to do find is a use for the rest of the 15 I/O pins.

i added the Serial RFID reader and both sections work in there own program but not in the same one ..
I used stock parallax code and did some trimming on the RFID package to make it be clean ..
If I uncommnet a section of code it gives me a Error stating "DATA occupies same location as program"
Peter
I did a copy paste in to a fresh BS2 file on a second computer and its not giving me any fits
what I am trying to do is If a valid card is at the reader at the time of scan GOSUB hello peter yada yada . but if no card is there at the time of scan pass on to the next message in the list ..
I think is the wait command thats messing with me //
Peter
This might help you in what you want to
it runs BUT here is the kicker . Unless I scan a card ( good or bad ) it will not pass over the RFID code back to the main code .
GOTO tagdone
tagdone:
RETURN
You have to tell your code where to go next
My device goals were 2 things . it reads a RFID reader so I can disarm a alarm and display a " welcome home peter " message .
it also displays a constant message if no RFID card is present ..
the last function is where I had to cheat .
I used a push tact switch to enable the GOSUB . IN3 is low then read .
as if I just go to it and do the RFID SUB as a poor mans polling ,
the code will hang and wait for a serial input .til the end of time .
I think its the wait command in the RFID read section .
I feel a Prop or some other 2 or more core MCU is needed .. OR interrupts.. both a BS2 cant do as far as i am aware

This what you have now
SERIN RX, T2400, [WAIT($0A), STR buf\10] ' wait for hdr + ID
Use this
This line time out then gose to other card reader
SERIN RX1, T2400, 150, Reader2, [WAIT($0A), STR buf\10]
Here where you would put your own code name routine I have this Reader2
