Project to apply 32 variable voltages

hey guys, i starting project involves applying voltage 0v -13v device.  applying voltage single 'part' alone easy , have function generator can that, apply voltage 32 different parts (on single device), doesn't make sense have 32 function generators.  figured using microcontroller make sense, unsure how proceed. will arduino solution looking for?  i'd interface labview, , develop ui control voltage each part recieves.  high level investigation, figure may need have additional transistor / op-amp each part in addition arduino.  (or use 2 arduinos). what guys think? yes, can done, it's quite complex setup. the arduino alone cannot generate kind of voltages after.  can generate analogue voltages 0-5v in form of pwm can low-pass filter, can generate few of them @ once. my suggestion use external spi dac chips, mcp4822 - each 1 can generate 2 stable precision voltages @ 12-bit resolution between 0v , 4.095v...

Trouble creating text fields

flash 8 pro here's one: the way can create text field to: - create 1 using action script, or - copy existing 1 on stage , paste new one. if try create new 1 on stage, doesn't seem enabled. for clarity, didn't have problem yesterday. yesterday, created number of text fields on stage, , seem work. today, follow same path, text field appears on stage, when execute app, field isn't there anymore. to test it, used getdepth find out of fields hidden somewhere. while text fields created yesterday returned depth, new ones don't. if copy 1 of yesterday's fields , rename it, works fine. so isn't huge problem, i'm worried possibility have create new field sometime, , don't have old 1 copy. any ideas?

Arduino e DAST ISD 4003-8

salute ragazzi, vorrei fare delle esperienze con arduino ed dast. ho una scheda, ft 537k, acquistata in kit da futura elettronica, scheda peraltro fuori produzione, monta un isd 4003-8, il processore è un pic 16f876, ha la possibilità di selezionare (registrare/riprodurre) 64 messaggi.  io vorrei gestire il 4003 con arduino, rifacendo ovviamente il pcb, portando messaggi 256 anche se molto brevi (diciamo parole), penso che indirizzando opportunamente la memoria potrei far "parlare" con la mia voce l'amico arduino, anche se con un vocabolario di 256 parole, che dopo tutto non sono poche. c'è qualcuno che ci ha provato o può darmi qualche dritta ? il fatto è che io non ho mai avvicinato il bus spi, ma posso sempre cominciare con questa opportunità, visto che "esso" dialoga così. dal data sheet risulta una flash organizzata in 1200 righe di 1600 celle ciascuna, calcolando gli 8 minuti totali di rec/play ne verrebbero, salvo errori,  256 parole da circ...

XMLSocket onData Issue

i trying narrow down bug in application utilizes xmlsocket class. have reduced following code below. there such scenario practically simultaneous messages sent server cause 'false' traced more once (ie. can code in ondata method evaluate test false more once because ondata called second time before first ondata method has had time update test true)? can ondata method treated atomic? degree....? at root of question, trying grasp how asynchronous calls handled/queued make sure understand them correctly , prevent cases single-time operation may occur twice. if 1 can or direct me information regarding this, thankful. dan More discussions in ActionScript 3 adobe

Where does PROGMEM stuff go?

back in work arduino, learnt supposed put hardcoded strings progmem. great - fill sketches , logfiles lots of useful messages. i've hit problems working sketch , have been led believe may down using progmem, or compilier writing wrong place. (something 64k limit? - not sure of details). anyway, result decided try prune of cr4p i'd left lying in file keep progmem stuff in. before started purging, when compiled project got following (on mega 2560 compiled on version 1.0)..... quote binary sketch size: 128420 bytes (of 258048 byte maximum) i removed of redundant progmem statements precompiler directive.... code: [select] //#define waste_of_space #ifdef waste_of_space   const prog_char igc_line_001[] progmem = "b1255275225709n00105715wa006780074700309";   const prog_char igc_line_002[] progmem = "b1255315225644n00105791wa006750074500310";   const prog_char igc_line_003[] progmem = "b1255355225559n00105822wa006780074300...
