i need send data (an integer) arduino c program on pc. know connection fine, because x-ctu works perfectly. need in @ mode don't know how start. if you're using xbee modules in @ mode, isn't different you'd have direct serial cable connection between arduino , pc. sample programs demonstrating serial communications both platforms. having connection working x-ctu excellent starting point, since have confirmed radio modules communicating correctly. on pc, might want @ open source xbee host library on github. includes sample program called "xbee_term" demonstrates simple serial terminal using xbee in @ mode. has layered api allow easy use of xbee modules in api mode -- need use if pc going communicate multiple arduino nodes running in @ mode. as sending int , can use sprintf() format string send on wireless link, , strtol() convert int on pc end.

i load image raw data , use qimage::format_monolsb format while loading. try write file, , image in b&w mono color format. ok. what way image out of in color format ? eg: if want color while portions particular color, how do ? i tried create qimage using qimage::format_argb32_premultiplied , , used painter draw 1 got above using pen/brush. not seem work. suspect there compatibility issue between formats. colorimage = qimage(qrect(0, 0, w, h), qimage::format_argb32_premultiplied); _painter.begin(&blockimage); _painter.setpen(qt::blue); _painter.drawimage(qrect(0, 0, w, h), blockimage, aboveimage); _painter.end(); i tried change loading code use color format (format_argb32_premultiplied ), not seem work either. no image in output. you're drawing blockimage on blockimage . think want paint on colorimage instead: _painter.begin(&colorimage); anyway, use qimage::converttoformat , pass in color table instead.

i know there errors in floating point multiplication there errors in purely integer multiplication? let's i'm using python, how large of integers , b can compute a*b , answers right? wall? same addition? there no error in (correct) floating-point multiplication. rounding may occur, that’s not error, that’s defined behavior of arithmetic. colloquially called “rounding error”, not “error” in normal sense of word. there no error in (correct) integer multiplication. in languages, overflow may occur, that’s not error, that’s defined behavior of arithmetic*. in python in particular, overflow not occur integer multiplication**; result equal “mathematically exact” result, , silently promoted bignum if necessary. same holds true addition. [*] there languages overflow produces trap or throws exception; again, however, that’s defined behavior in languages. [**] long result isn’t large storage cannot allocated.

how can manipulate regular expression string onecmd = "([0-9]+\\.[tcm]{1}\\#.+\\#[wsn]{1})"; to avoid matching "100.m#testvalue#w100.m#testvalue#w" but allow matching 100.m#testvalue#w ? because in end want there can multiple commands separated | string regex = "^(" + onecmd + "$|" + onecmd + "\\|{1}" + onecmd + "$)"; so valid commands are: cmd cmd|cmd1|cmd2|... not ending '|' !! but first problem if concatenate 2 or more commands still valid. i think readable way first split on | , apply regex allows 1 match: ^[0-9]+\\.[tcm]#[^#]*#[wsn]$ if want find matches separated | and/or start/end of string, can positive lookahead assertions instead of ^ , $ anchors: (?<=^|\\|)[0-9]+\\.[tcm]#[^#]*#[wsn](?=$|\\|)

i have activity searchview under test, works expected tests fail. @override protected void setup() throws exception { super.setup(); intent intent = new intent(getinstrumentation().getcontext(),startactivity.class); startactivity(intent, null, null); } @smalltest public void testshouldcreatestartactivity() { assertnotnull(activity); } the test fails because of searchmanager.getsearchableinfo(activity.getcomponentname()) returning null. searchmanager searchmanager = (searchmanager) activity.getsystemservice(context.search_service); searchableinfo searchableinfo = searchmanager.getsearchableinfo(activity.getcomponentname()); very frustrating have working app code tests fail. i changed test class activityunittestcase activityinstrumentationtestcase2 , works. read more differences here : difference between activityunittestcase , activityinstrumentationtestcase2

i have read out bytes of uint32_t variable, , have seen kind of implementation colleague of mine. question is, if behaviour of code-example reliable on "nearly every" 32bit microcontroller. supposable work on every 32bit microcontroller or platform-specific behaviour relying on? p.s.: endianness of system shall not considered in example. uint8_t byte0=0; uint8_t byte1=0; uint8_t byte2=0; uint8_t byte3=0; uint8_t *byte_pointer; //byte_pointer uint32_t *bridge_pointer;//pointer_bridge between 32bit , 8 bit variable uint32_t var=0x00010203; bridge_pointer=&var; //bridge_pointer point var byte_pointer=(uint8_t *)(bridge_pointer); //let byte_pointer point bridge_pointer byte0=*(byte_pointer+0); //saves byte 0 byte1=*(byte_pointer+1); //saves byte 1 byte2=*(byte_pointer+2); //saves byte 2 byte3=*(byte_pointer+3); //saves byte 3 thanks in advance byte0=*(byte_pointer+0); //saves byte 0 this line (and following o...
