Propeller for me?

I have a small project where i require:

1. Usage of a standard mini PS2 keyboard to check for F1-F9 and entering a few commands.
2. send/receive RS232 text at 9600baud
3. LCD display

Using the BasicStamp2 seems to limited and to much "work".

Is the propeller the right tool for this? I have been reading about the propeller but compared to the BS2 information on the web i feel that the propeller is a bit more "unorganised" so i'm not sure if this is for me.

I'm thinking of buying Propeller Starter Kit + Free! Official Guide as this is probably the cheapest to get starting even after 25%VAT and $30 fee to the custom.

    you could probably get away with writing that serially in a stamp, but you would rally benefit from the parallel processing capability of a propeller doing all three of those things at once. if you only have little experience in either pic's or the propeller i would really recommend investing the time into learning spin and the propeller. what you want sounds like a relatively easy program to write (if you intend on using just a serial LCD..) and would be a great first project with hopefully many more to come

    Propeller is perfect, check out the education labs for a step by step structured introduction.

    You're correct that the Propeller is a bit more "unorganized". The book that you mention is very good, and IMO a better intro that the other docs.

    You can preview it on Googlle books: books.google.com/books?id=3MEAXiZtQuEC&printsec=frontcover&dq=Programming+and+Customizing+the+Multicore+Propeller+Microcontroller&hl=en&ei=Bd1ZTLS4LIiHnQfLqfXpCA&sa=X&oi=book_result&ct=result&resnum=1&ved=0CDAQ6AEwAA#v=onepage&q&f=false

    tnx for the previewlink smile.gif

    I know that the propeller is "overkill" for just reading a keyboard, sending/receiving a few words to a RS232 and showing this in an LCD.

    But if i'm correct i would have everything in that chip. For the BS2 i need more memory to work on the text i'm receiving as i have to parse it.
    I also need several parts just to use a keyboard.

    The LCD i really don't need but if i'm using the propeller then the project could grow to an small 8"

    So i'm guess that i'm lacy not trying this project on a BS2. But for me the propeller probably solves most of my needs with virtual NO extra hardware.

    Consider also the impressive object exchange. You'll find objects ready for doing 99% of your separate tasks. You'll need to write the code to combine them, but it is a great starting point.
