welke programmeertaal leren?

hoi allemaal. een absoluite beginnersvraag. ik werk al een aantal jaren als zelfstandige in de videoindustrie en loop telkens tegen het feit aan dat ik niet kan programmeren. wanneer ik de uren die ik de laatste jaren heb verspild met het zoeken naar gui's voor programmaatjes zou hebben gebruikt om te leren programmeren, zou ik nu al polyglot zijn denk ik. website bouwen? wordpress en een theme gebruiken, daarna knoeien met css. videoproblemen oplossen? tooltjes zoeken zonder commandline. etc.. nu zijn er een aantal dingen die ik de komende jaren zou willen bouwen: - een uitgebreide website met veel functionaliteit (heb een heel erg cool idee liggen)  (javascript) - een video control panel en midi controller gebaseerd op arduino (c) - een applicatie maken die werkt met directshow filters (c) - webapps bouwen (javascript) verder het essentieel dat ik ooit eens begrijp hoe xml nu juist werkt, daar kan ik handige dingen mee doen die met video gerelateerd zijn. het gemakkelij

Weather Rstation Receiver decoding

hi all, i have old weather station outdoor , indoor unit. screen of indoor unit base broken, pcbs in working condition. have found receiver pcb inside part no sl-rx585 , has 3 wires connected main pcb. want receive weather information outdoor unit pc, @ least show information in console use of receiver pcb. my weather station: http://www.ebay.com/itm/191376324853 i have connected a-d-c wires of receiver pl-2303 usb ttl amusing gnd d rx , c tx. , getting data receiver can`t decode it. receiving data when outdoor unit makes transfer (red light comes on). use realterm console software log incoming data through usb < pl2303 < sl-rx585. i have tried many realterm settings combinations (1600bps, 1200 bps) , getting unreadable data. please give me idea how can convert data readable format incoming unit. thanks in advance. weather station rf remotes encoded proprietary methods, many have been decoded. usual way figure out have first examine transmissions au

Servo timer corruption?

hi, i've been working on project uses servo.h library. working ok, project has  stopped working (i.e. servo won't move.) have worked servos lot in past, reasonably confident i've avoided of basic issues. the hardware (arduino pro mini , futaba servo) seem working correctly - can upload of earlier servo projects , works fine. code compiles , uploads expected, , know servo.writemicroseconds() function being executed correct values, problem servo won't move. here's theory (and question forum). know servo.h library uses 1 of timers, , know these timers require use of registers. these registers part of 'normal' dynamic memory, or in way protected? can corrupted normal memory can be? my current best guess somewhere in code have managed corrupt 1 or more of registers servo.h timer uses. (i have never knowingly changed of registers). if theory plausible, there way of checking it? thanks the common cause of timer problem 2 libraries usi

Sim 900A module problem

i bought sim900 module ebay because smallest 1 find. see attached photos. sadly not connecting network @ all. can sent @ commands device , read out data (using gsmshield library) status light blinks every second. the sim vodafone uk sim, know theres 900mhz transmitter 200meters away. tested sim in normal phone , worked fine. have tried powering module 2a 5v supply didn't make difference. understand module try connect automatically when given power regardless of serial connection being present. have not been able magical 3 second blink! has used particular module before? i'm using default example sketch library. see below. code: [select] #include "sim900.h" #include <softwareserial.h> //#include "inetgsm.h" //#include "sms.h" //#include "call.h" //to change pins software serial, use 2 lines in gsm.cpp. //gsm shield arduino //www.open-electronics.org //this code based on example of arduino labs. //simple sketch communicate s

Minor portability oversights in XMP code

hi, this isn't question, rather comment adobe developers. in working code noticed 2 minor portability oversights thought i'd mention. (but should code nicely portable, these quibbles saw.) first, in xmpgizmos.cpp source (part of samples/xapdumper), there's macro provided @ beginning take account pre-standard stl implementations (such provided gcc 2.95.3, still ships conservative releases of few open source oses), attendant iosbase macro isn't used consistently in code, causing compile errors. extremely trivial fix, i've attached unified diff below. --- xmpgizmos.cpp~ tue may 20 14:36:10 2003 +++ xmpgizmos.cpp sat nov 13 18:39:36 2004 @@ -292,9 +292,9 @@ cout << " = \"" << value << "\""; if ( features != 0 ) { cout << ", features = 0x"; - cout.setf ( ios_base::hex, ios_base::basefield ); + cout.setf ( iosbase::hex, iosbase::basefield ); cout << features; - cout.setf ( ios_base::dec, ios_base

Add code to internet radio program? - Raspberry Pi Forums

Image
hello everyone, happy new year! making internet radio project based 2 related tutorials , works nice after few first tests did today. appears both tutorials did not include volume control via buttons on gpio. found code think add python program, don't know how program in. not sure how add code program. internet radio program using http://usualpanic.com/2013/05/raspberry ... net-radio/ code add internet radio program... best way this? code: select all if (volup==true): if(gpio.input(17) == false): lcd_byte(lcd_line_2, lcd_cmd) lcd_string("lauter") #print "lauter" os.system("sudo mpc -q volume +1") #sleep(.1) volup = gpio.input(17) if (voldown==true): if(gpio.input(22) == false): #print "leiser" lcd_byte(lcd_line_2, lcd_cmd) lcd_string("leiser") os.system("sudo mpc -q volume -1") #sleep(.1) voldown = gpio.input(22) appreciated what if you put code: select all if(gpio.input(17) == false: os.system("sudo

Problem receiving bytes from VB.NET

hi everyone! i'm designing particular project in serial communication in important. i try explain system in few words: vb.net program sends arduino letter recognized, arduino sends data sensors, vb.net program elaborates these data , sends arduino 2 bytes. these 2 bytes represent logic states have written 16 digital pins (one bit each pin). now, arduino recognizes letter sent computer, program receives data arduino correctly , creates final 2 bytes perfectly, here comes problem! arduino receives 2 bytes (i think), uses bit masks , tries write obtained values digital pins, these digital pins behave in wrong way , don't understand how work! here vb.net code specific part: code: [select] dev16to9 = dev16to9array(7) * 128 + dev16to9array(6) * 64 + dev16to9array(5) * 32 + dev16to9array(4) * 16 + dev16to9array(3) * 8 + dev16to9array(2) * 4 + dev16to9array(1) * 2 + dev16to9array(0)         dev8to1 = dev8to1array(7) * 128 + dev8to1array(6) * 64 + dev8to1array(5) * 32 + dev8to
