Re: newLISP and my AR.Drone 2.0

I actually bought a "used" AR.Drone. It was in a pretty good shape and I could test it before I bought it.

newLISP and my AR.Drone 2.0

I wrote a few functions that allow to control the Parrot AR.Drone 2.0 with newLisp.
You can find the code here: https://bitbucket.org/StefanLiebig/dragondrone

Any kind of feedback is welcome!

Tschüß,
Stefan

Getting keyboard "key events"

For a simple "game" (console based) I need to get the keyboard "key events" from my Mac. (read-key) seems to be a good choice, but unfortunately some keys (or modified keys: shift, ..) do require following (read-key)s. Worse on Mac is that "cursor up" results in three (read-key)s returning: 27 91 65...

Yep, that's the reason.

UDP example client does not start

I am currently playing with UDP (no experience with it yet). For getting things started I tried the example udp client and server from http://www.newlisp.org/CodePatterns.html#toc-13 . Server started, but the client reports an error: newLISP v.10.6.0 64-bit on OSX IPv4/6 UTF-8 libffi, options: newli...

Re: (flt -0.8) on OS X and Win

Right! The (add 256) in bit 9 will be set for 64-bit (changeable at runtime) versions (add 256) (http://www.newlisp.org/downloads/newlisp_manual.html#sys-info) could have told me this. I really did not know how to interpret it. ps: Currently I am glad that it is a signed integer. :-) Thanks, Stefan

Re: (flt -0.8) on OS X and Win

After browsing the good documentation I found ".init.lsp" for automating this: ;; set local to the "C" locale on UTF8 (if utf8 (set-locale "C")) ;; test for 32-bit-ness (define (bit32?) (= (& (sys-info -1) (<< 1 9)))) ;; define flt32 depending on the bit-ness (if (bit32?) (constant 'flt32 flt) (defi...

Re: (flt -0.8) on OS X and Win

Thanks for the explanation and the code snippet for the integer representation. Although, I am not really sure what is happening there. "first" of the result of "unpack" - what is unpack in this case returning? However, the locale dependency scares me a little bit. Should the parsing of literals not...

(flt -0.8) on OS X and Win

I need the integer representation of single-precision IEEE-754 floating-point value.
