Error Message Says File Doesn't Exist...

hello. i'm trying install cf website on same server asp website , running. both sites access same foxpro data, may lead conflicts i'll have work around, first there's problem have solve: when try sql select statement, i'm being told error message table want not exist, false. specifically, both asp site , own site use same odbc connection, specifies visual foxpro driver , path foxpro tables (which need foxpro tables through odbc). it might appear should have connection of own different name, seems unlikely because have, in fact, set separate connection in odbc, different dsn (obviously), , pointing entirely different directory have placed clones of foxpro tables want access. , did not forget change dsn name appropriately in sql select statement. nonetheless, receive same error message in situation. full error message provided after double lines below. i should mention have pointed coldfusion adminstrator both odbc connections (both 1 used asp site , 1 used clone tabl

Mosfet + ventola 12v

Image
salve tutti, dopo qualche settimana ho ripreso in mano il mio progetto per completarlo. sono rimaste le ultime cose e dovrei farle funzionare tutte allo stesso modo... con un transistor. ho provato una ventola da 12v seguendo il pdf di pighixxx e funziona, ma non ho capito alcune cose, vi lascio un'immagine del circuito qui . il cavo blu va al pin 9 di arduino, due cavi nero e rosso che spuntano dall'altro sono quelli della ventola, quello nero in basso 53 va al gnd di arduino e gli ultimi due sulla destra vanno all'alimentatore da 12v. le mie domande sono... dove va il condensatore? la resistenza da 100ohm va tra il gate e il pin di arduino, giusto? perchè con una da 220ohm (non ne ho più piccole) la ventola smette di girare. e infine... la resistenza da 100kohm, va tra il source e la massa? per concludere vi lascio le info dei componeti: ventola 12v - 80ma (in alternativa ho provato una 5v - 110ma) diodo 1n4007 mosfet irl540npbf grazie mille per l'aiuto!

Freerunning A2D on Due

hi, i'm quite new arduino, , due, have lot of experiance programming avrs via avr studio. one of reasons i've moved due massively faster a2d capability.  want run a2d channel @ 100khz.  sam3x datasheet, looks sort of speed should no sweat chip... not clear me how might through arduino libraries. as far can tell, on avr based arduinos if want freerunning a2d conversions, programming avr chip directly without arduino ide.  okay, i'm game. but i'm not sure how works due. does have examples of how access , manipulate underlying due functionality?  far in explorations not seem straight forward writing bits registers in avr method. better yet library allows me freerunning a2d conversions , attach completion interrupt!  thanks much, se Arduino Forum > Products > Arduino Due (Moderator: fabioc84) > Freerunning A2D on Due

GRBL Capabilities

hi, i stumbled upon grbl while trying cnc-ready development environment , curious actual performance real-world 3 axis controller. kind of speed/inches per minute can expected, compared full blown linuxcnc or mach3 setup? most importantly, arduino/microcontrollers posses "real-time features" due simplified electronics? surprized, shocked even, @ how arduino/grbl seems overcoming biggest hurdle...real-time pulse consistency. any input/observations people using grbl appreciated. regards, bill i think find little grbl info on forum. there grbl forum or wiki? , try of cnc forums. as far know grbl uses same gcode thal used linuxcnc or mach3. presumably performance depends on mechanical setup driving? ...r Arduino Forum > Using Arduino > Motors, Mechanics, and Power (Moderator: fabioc84) > GRBL Capabilities

Sparkfun Serial LCD Kit Bricked. (SOLVED... mostly)

i've purchased serial lcd kit sparkfun (https://www.sparkfun.com/products/10097) , messing code, trying mesh menubackend code found here: http://www.arduino.cc/playground/uploads/profiles/menubackend_1-4.zip well, pain, loaded original lcd code onto lcd's chip, , menu code onto uno, , tried 2 talking via tx/rx pins. worked, kind of. long story short, screen started printing gibberish , randomly changing backlight intensity, reloaded lcd code again , powered lcd, time unconnected uno. when splash screen came on, characters in wrong spot. looking @ code, obvious board thought running 20x4 character display, when running 16x2. couldn't convince otherwise novice level tinkering, said f*** , reset chip's eeprom try rid of data wouldn't rewrite. that seems have been bad idea. now i've got screen nothing. blank. no apparent activity. bricked. the chip seems fine. i've written sketch it, , saw results via serial monitor. can't activity out of screen. a

Smoothing Capacitor value?

Image
hi everyone! i have question "smoothing capacitors". have 5v arduino project have 6 individual 5v components attached it. since need these running @ different times, wanted take similar approach of nick gammon's in helpful example (http://www.gammon.com.au/forum/?id=12106) , use few mosfets switch these little guys on & off individually (instead of regular arduino pins), while minimizing potential power surges affect microcontroller and/or components themselves. these components 5v, , have maximum draw of ~170ma when powered on @ same time. so, if used 6 different mosfet switches turn switch +5v power line on each component directed via arduino uno, wondering: 1. still use 1 capacitor (like nick did in example)? 2. capacitor of 100uf work, or should use bigger? my plan first test circuit mosfets & capacitor(s) using usb, , later on, moving project battery power. thanks in advance ideas & suggestions! quote these little guys what

timer interrupts

i want use timer interrupts activated conditionally, , i'm trying use duetimer library @ https://github.com/ivanseidel/duetimer. don't see examples using detachinterrupt() , arduino command requires pin number in detachinterrupt() parentheses, don't understand how stop timer interrupt using detachinterrupt(). thank suggestions.  you call timer.dettachinterrupt() detach handler that timer object.  can re-attach later if like, or whatever.  unlike the arduino attachinterrupt there object each timer channel, not a global object external interrupts, no need identify channel.

Problemi nella misurazione della carica di una batteria con attiny85

poichè mi serve misurare la carica di una batteria lipo da 1 cella e pilotare un transistor in modo che mi spenga tutto se la batteria è scarica, ho pensato di usare un attiny85 con cui leggere il voltaggio della batteria tramite analogread(). il codice che ho usato è il seguente: code: [select] void setup() {   pinmode(pb4, output);   digitalwrite(pb4, high);   pinmode(3, input);   pinmode(pb2, output);   digitalwrite(pb3, high); } void loop() {   int sensorvalue = analogread(3);   float voltage = sensorvalue * (5.0 / 1023.0);   if(voltage < 3.1); {     digitalwrite(pb4, low);   }   if(voltage > 3.1) {     digitalwrite(pb4, high);   }   delay(1); } tuttavia, testando il funzionamento tramite un potenziometro usato come partitore di tensione (il pin centrale collegato all' ingresso analogico e gli altri due pin uno gnd e uno +5v) e un led al posto del transistor, ho notato che quando il valore è vicino ai 3.1 volt, il led non rimane spento, ma lampeggia, mentre sce

hello all, i can't seem find information online this. use arduino due deliver analog signals series of experiments have coming up. need deliver signal ~5 mv. how peak peak noise should expect in due's dac? thank tremendously information can provide. thanks, fb you won't able output 5mv directly. need use voltage divider (resistors) achieve it. i can't find source anymore, due's dac output 1/6 5/6 of full (0 3.3v) voltage range. hence analogwrite(dac1, 0); correspond 0.55v, , goes 2.75v (ish) noise depend on how current drawn, emf , capacitors use. experience should few  millivolts, depends on making due compute (timer interupts, etc) Arduino Forum > Products > Arduino Due (Moderator: fabioc84) > Noise in Due DAC arduino

Thread: Brand new MicroSD protected from writing

hi, saw few other threads on subject, none have solution, decided start scratch. so, have microsd works fine here. decided buy new one, sandisk, , found out write-protected. thought of manufacturer, bought kingston(just 1 have , works fine), it's write-protected. 1 works accessed through sd adapter, , both others accuse protection, though they're both new. tried them on vista, can't formatted either. and, yes, i've checked "lock" switch on adapter. here's line on fstab sd cards: code: /dev/mmcblk0p1 /media/sd auto user,exec,rw 0 0 and here's got on dmesg working card , 2 cards don't work code: [246217.464749] mmc0: new sdhc card @ address 7f73 [246217.466355] mmcblk0: mmc0:7f73 sd04g 3932160kib [246217.466755] mmcblk0: p1 [246242.240132] mmc0: card 7f73 removed [246267.275170] mmc0: new sd card @ address 1234 [246267.276535] mmcblk0: mmc0:1234 sa02g 1927168kib (ro) [246267.285772] mmcb

programacion de leds horario mega-rct

hola que tal soy nuevo en este mundo  de arduino,tengo un mega 2560 -placa de relays 8 canales y un modulo rtc(real time clock) ya todo esta instalado el reloj esta en hora actual todo trabajando correctamente. tengo un acuario en el cual tengo 8 leds 10 watts  12v . quiero encender  y apagar cierta hora  simulando el anochecer alguien con experinceia es esto o algun link de algun tutorial ,se agradeceria mucho http://www.tuelectronica.es/tutoriales/arduino/reloj-rtc-i2c-con-arduino.html    son los pasos que segui para configurar la hora  al poner los nuevos comandos se borrara la ora o tendre que poner los del reloj tambien? puedo conectar el arduino 2560 la fuente de poder ,tendre que poner algun fusible 500ma o no es necesario ya que tengo una fuente de pc con la que  se encuentran los leds. gracias  hola 7orres, la hora se establece en el rtc mediante esta linea: rtc.adjust(datetime(__date__, __time__)); solo es necesario usarla una vez para configur

OSX 10.5.2 and AR8.1.2 playing swf files

after applying latest apple updates osx 10.5.2 find can no longer play swf files within pdf file. i'm using ar8.1.2 fp9,0,115,0 . consider the example: http://www.amrita-cfd.org/4adobe/swf/swf.pdf it contains /annot "click activate swf!" supposed to play swf, when click it: progress bar "buffering" appears in bottom right corner of screen , hangs. swf file is included attachment, shock-tube.swf, can opened in external viewer , don't think swf file is problem. i have same problem pdf available at: http://acrobat.timhuff.net/?p=92 where swf embedded using acrobat, rather homebrew approach. i grateful if shed light on problem. thanks, james quirk More discussions in Adobe Animate CC - General adobe

Lampara que cambia de color

hola todos, tengo entre manos un proyecto que consiste en una especie de lampara con un par de leds rgb y que al girarla cierto angulo, esta cambie el color de los leds. para tal proposito me comprado unos cuantos leds rgb, los cuales ya aprendido hacerlos funcionar, y un imu (unidad de medicion inercial). el imu consiste en un acelerometro (adxl345), un giroscopio (itg3205) y una brujula digital (hmc5883l). salvo la brujula, tengo funcionando por separado el acelerometro y el giroscopio conectados por i2c al arduino, ahora empezado mirar el tema de medir angulos pero ando un poco perdido con el tema. leido sobre filtros kalman que calculan el angulo en funcion de las mediciones del acelerometro y el giroscopio, tambien leido que con tan solo un acelerometro se podria hacer mediante trigonometria. me gustaria saber si alguien me podria orientar mas sobre esto, porque ando un poco perdido... pd: si alguien lo necesita puedo subir el sketch del acelerometro y del giroscopio.

Wizfi Shield wizfi210

hi everybody, have bought wizfi210 , arduino uno rev 3 i have cliped shield on arduino. if shield not on board, can blink arduino , works, or when shield on board, blink doesn't work , error: avrdude: stk500_getsync(): not in sync: resp=0xdc i know shield works because power led on. what's more, using serial monitor, achieved connect wizfi210 on wifi connection wpa password. the questions are: how can transfer code in board shield??                                      how can send data in database on internet site? thank lot! best regards adel which shield using? wizfi 210 module has 4 ports communicate mcu, , different shields might use different wizfi module port. sainsmart shield, example, uses uart (serial) uno-wizfi link. prevents uno communicating pc, because uno-pc connection uses same port. if case shield, too, program uno without wifi shield, disconnect pc, (unplug power if powering uno external power supply, too), connect shield, , pow

IDE 1.5.6-r2 vs. Ubuntu e YUN ttyACM

ciao tutti, sto incontrando un po di problemi fare l'upload degli sketch su l'arduino yun da ubuntu e la suddetta versione dell'ide. procediamo con ordine. prima avevo problemi di permessi con qualsiasi arduino che usavo (uno e duemilanove ) per  accedere all'usb poi li ho risolti aggiungendo il mio user al gruppo di ttyusb0 e dandogli permessi necessari. con lo yun però è diverso. mi viene rilevata una ttyacm1 , non ho problemi di permessi in questo caso, ma proprio mi si blocca il caricamento dello sketch. ho provato fare le stesse cose di quelle che facevo con ttyusb0, ma non è servito niente. qualsiasi sketch carico dal blink al bridge, mi fa sempre la stessa cosa. mi potreste illuminare? c'è un pò di confusione in quel che hai scritto. la uno non ha un convertitore hw ma un chippino programmato per emulare tale dispositivio per cui viene montata come seriale virtuale appunto, e quindi ti deve apparire come ttyacmx. la duemilanove
