Hello,
· I would like to know if there is a way to·interface my BS2 to my computer so that I can have the BS2 read input from the computer's keyboard while a program is running.· Is there a command for reading the computer's keyboard?

thanks,
agentile·

    Type

    SEROUT 16, baud, [noparse][[/noparse]"Enter command", cr]
    debugin com·· 'Type an A

    The debug screen will say

    Enter command
    A

    If you want to send a string to the debug screen declare

    serstring var· byte(8)

    Then instead of debugin write:

    SERIN 16. baud, [noparse][[/noparse]serstring\8]

    You willl have to enter 8 characters - no more, no less.

    For more info see the Help file.

    Sid,

    · Thank you.· This is excellent.· What I want to do is to use the BS2 as a calculator using the keyboard as an input.· This project is intended to demonstrate·the limitations of non-floating point arithmetic, and also to·underline the importance of·accurately sizing variables.· Anyway, since we are only entering numbers and operators (single characters), it seems that with a little manipulation of the inputs, this project will work out well.· Thanks again.

    P.S. Do you know of·any examples of this type of code available in the archives?

    Is there anyway to cost effectively interface it with a PS2 keyboard (stand alone). I know using a USB keyboard would require a USB chipset and hardware programming to interface to it. Just curious if anyone has done this.

    How about interfacing to a SVGA monitor (The closest think I have is the SX video module which is pretty cool in itself) - but I am guesing this would require much more hardware (e.g. video card interfacing that may be too much for a single BS2 chip).

    People have also reported success using the ezKey http://www.multilabs.net/ezKEY.html

    Some people have kicked around the idea of a svga monitor driver, but I haven't seen someone discuss completing the project.

    FYI:

    If you can find an old UNIX SUN-workstation keyboard, the output is RS232 (5V levels) 1200 baud.

    Besides the Multilabs ezKEY they also have color video modules www.multilabs.net/Products.html that you could use to make an on-screen calulator.· Even cooler would be to use their ezMOUSE with the ezVID 2.0 which has a floating character to make a pointer.· Then you could just draw the calculator on the screen and the user could move the pointer around on the screen and click on the numbers and operators on-screen.· tongue.gif
