New to Propeller - can't compile keyboard.spin object

Chuck Davis

I just got my propeller starter kit and am trying out various things:

I can't get the keyboard object to compile; it gets an error on the last line of the code snippet shown below:

configure··········· mov···· data,#$F3·············· 'set keyboard auto-repeat
······················· call··· #transmit
······················· mov···· data,_auto
······················· and···· data,#%11_11111
······················· call··· #transmit
······················· mov···· data,#$ED·············· 'set keyboard lock-leds
······················· call··· #transmit
······················· mov···· data,_locks
······················· rev···· data,#-3········· '******·· ERROR ON THIS LINE


Error states· "·Source Register/Constant cannot exceed $1FF"· I tried changing the -3 to just 3, which eliminates the error but I can't get the keyboard demo to work after compiling it.· Any thoughts???

Get a new copy of the object....

" Source Register/Constant cannot exceed $1FF" is the compliers way of saying
out of memory.

That line is supposed to read:

rev···· data,#-3 & $1F·

Just apropos: It would have been much cleaner to say:

rev     data, #32-3

No offence! I had my tutorial in mind, and there is so much to say... exactly such kinds of things: "Dos and Don'ts"
