Image
hello, i'm sorry english. it whether possible use library "pin change interrupt" arduino leonardo? if yes how use it? if has example, take . thanks you. quote it whether possible use library "pin change interrupt" arduino leonardo? yes, is, on pins support pin change interrupts. unlike uno, not pins on leonardo support pin change interrupts. http://arduino.cc/en/reference/softwareserial quote not pins on leonardo support change interrupts, following can used rx: 8, 9, 10, 11, 14 (miso), 15 (sck), 16 (mosi). quote if yes how use it? to what? there examples come library.

Thread: Interesting problem

i got wireless working yesterday (yea) , worked fine afternoon. today tried online again. in family room, have 4 bars on signal strength meter (80%) , when tried open site message "address cannot found". can't on anything. if carry computer room router meter goes 5 bars (100%) , works fine. if go family room , turn off ubuntu , open vista (4 bars again_) works fine again. 1 have problem , have comments, suggestion. surely 1 bar on signal meter not make difference. have run less 4 bars before , woked. i had similar problem. think it's known bug or @ least known issue specific type of wifi adapters. running folowing command may solve problem code: sudo iwconfig ath0 rate 5.5m replace ath0 name of wireless adapter. run code: iwconfig to find out name, if don't know it.

Pausing a for loop to wait for result

i trying cycle through array , send each element database, don't want next element sent until previous element has returned result. not sure how in actionscript? ideas? if array large take while each single element represent single http exchange. if subsequent values being sent not changing result of each individual one's response server inclined send them @ once. (within reason... if there huge amount perhaps helpful split them also). you you're describing using loadvars or xml (depends on data type in each array element, , on preference) , using sendandload method send server script processes each element , send response sendandload method's receiving target argument (usually same type: either loadvars or xml). start sequence again in receiving object's onload handler. check out of examples loadvars.sendandload or xml.sendandload in files. or may want investigate remoting (e.g. amfphp etc) More discussions in ActionScript 1 and 2 adobe

Read from one USB serial source and write to another with a Leonardo

i use leonardo data translator, searching "leonardo serial" or various synonyms generates millions of not helpful hits. i have device spits out data on usb serial connection (several nmea sentences weather station). unfortunately, trying hook several of these instruments low powered computer. because stations streaming data separate standard nmea sentences extraneous fields instead of sending single short custom sentence once per second, computer getting bogged down polls different serial ports , tries grab data. use leonardo read , parse sentences, picking out data want (and simple intermediate calculations), , spit desired data single sentence on other serial usb computer. i know leo has 2 serial ports, serial which communicates on usb port , serial1 which communicates on digital pins 0 , 1.  can't seem figure out can wire usb plug +5/gnd/tx/rx , have work, or need intermediate translate? if can wire plug up, of usb pinouts i've found have +5/gnd/+data/-da

Help with servo project

hello, i started project have use , arduino micro control servo. being complete noob, after setting circuit servo, servo doesn't seem move after compile , upload example sweep program. made sure correct board , serial port selected. did forget set in program? i took couple of pictures of circuit: http://imagizer.imageshack.us/a/img856/738/yn2a.jpg http://imagizer.imageshack.us/a/img21/3500/ibqb.jpg thanks in advance guys, , sorry if question stupid. questions never stupid, show willingness learn. can arduino deliver power servo's need? otherwise must use (power) transistor , separate power supply servo's. in fact idea. furthermore can measure signal multimeter (mandatory tool!) check.

transmission - separate download folder - Raspberry Pi Forums

hi all, i've question transmission daemon. know if possible choose (for every torrent file load via web interface) right folder download file. example : (my download directory) /media/download "download" directory want create, example, 2 subdirs "linux-distros" , "movies" when load torrent file can choose in folder has downloaded. possible ? if yes, how ? thank in advance ! when add torrent through web interface includes entry box destination folder; if folder exists can specify there. raspberrypi

Loading a Picture onto the Scene

i trying load picture onto scene using following action script commands: on (release) { loadmovie("kjole1.jpg", ramme); } nothing happens when button released, doesn't work. "kjole1.jpg" picture file in same directory. "ramme" squere on scene converted movie clip symbol. when check, message "the script contains no errors", nothing happens anyway. what problem? >>"ramme" squere on scene converted movie clip symbol. if movieclip has instance name of ramme , jpeg indeed in the same folder swf, should work. -- dave - head developer http://www.blurredistinction.com adobe community expert http://www.adobe.com/communities/experts/ More discussions in ActionScript 1 and 2 adobe

GPIO port on Pi 2 - Raspberry Pi Forums

i have c programs i've linked minimalgpio library pigpio sight, , work pi model b+. programs appear compile , run on pi 2, not turn of ports on or off did on model b+. python3 library , programs use turn gpio ports on , off on b+ work on pi 2. q1. gpio pins numbered differently on pi 2? q2. have working example of c program maybe linked library turn gpio ports of pi 2 on , off? i think mean minimal gpio access http://abyz.co.uk/rpi/pigpio/examples.html#misc_code updated pi2 , should work. perhaps using old copy. minimal clock access code has not been updated pi2. raspberrypi

DSB instruction and ARMv6 - Raspberry Pi Forums

i'm working on port of mit/intel cilk runtime arm viewtopic.php?f=33&t=102743 , trying put binary package runs on both original raspberry pi , new pi 2b. difficulty pi 2b needs dsb data synchronization barrier instruction manage multi-core hardware whereas original pi doesn't have instruction. make definition #define __cilkrts_fence() __asm__ volatile ("dsb") in runtime source , works fine on pi 2b. binary equivalent to #define __cilkrts_fence() __asm__ volatile (".word 0xf57ff04f") again works fine on pi 2b , has advantage can compiled assembler in armv6 mode. not surprisingly resulting binary gives "illegal instruction" trap when run on original pi. therefore, need insert code tests cpuid register , makes relative branch skip past dsb instruction if cpuid armv6. logically code should function as if cpuid != armv6 dsb , written in inline assembler. while expect simple enough, i'm complete noob @ arm assembler ,

PSD import problem

hi, this hard explain. the problem occurs when import psd , layers have feathered edges (or transparency). import multiple layers single psd separate flash layers. if each layer set import flattened bitmap, feathered edge of each layer pick pixels of layers overlaps no longer have feathered edge overlap occurs. it's if top layer acting aliased mask on bottom layers. if import each layer individually, not occur, pain in neck import several layers individually. this problem not occur when import layers movie clips, lose ability apply smoothing , control compression if import way. is bug or feathered edges supposed pick layers overlap? if question isn't clear, can send images. also, if bug, contact @ adobe address problem on future versions? thanks i noticed same problem when tried import bunch of layers had transparent backgrounds...it has bug, annoying bug. let me know if find solution.

hi together, need in our project. http://fs2.directupload.net/images/150407/d7mpw7mf.png simple circuit control lamp on raspberry using pcf expander board, relay switching lamp (~230v). relay switched via expander board. once lamp switched on or off normal lightswitch, raspberry should receive information status has changed. know options send 5v signal input pin of expander board, if circuit (~ 230v) closed or open? need solution in form of possible small , cheap board, preferably in combination relay. following board should work, need assessment. there better solutions? http://de.aliexpress.com/item/free-ship ... 82240.html http://de.aliexpress.com/item/5a-ac-cur ... 68708.html regards, daniel assenda wrote: the relay switched via expander board. pcf8574 board bad idea that. consider mcp23017 or little sister 8 gpio (much, much, better) raspberrypi
