Using EEPROM to store an array

i'd store 4 digit passcode eeprom.  i'm thinking of doing following: code: [select] char passcode[4] = eeprom.read(1, 2, 3, 4) does make sense?  is there simple way read eeprom directly array? quote does make sense? yes. work? no. quote is there simple way read eeprom directly array? use loop read value each element of array.

A question about file extentions of tabs in IDE.

Image
 i'm starting write larger sketches , finding out how important organization of code larger program becomes. i'm using arduino ide compsose code , started using tabs break code semi-managable chunks. when named tabs didn't give extention names (didn't know could). ide treat code if 1 big file.  then learned little making them header files , "#include"ing them main sketch enables me isolate different sections of code , localize variables within them. useful!  somewhere in learning section on arduino site  i came accross - tabs, multiple files, , compilation: allows manage sketches more 1 file (each of appears in own tab). these can normal arduino code files (no extension), c files (.c extension), c++ files (.cpp), or header files (.h).  my question is, difference/use of using .c or .cpp extentions in tabs of arduino ide. there benifit in doing that. know libraries have have both .h , .c files. better off learning how write libraries. which, way, li...

Right Click Problems in Flex 2

is there way detect right click on display object? i have added event listeners mouse events , right click never fires anything. this needed because have flex app reads data service, displays data using display objects, , allows user interaction via mouse. right clicking object causes custom context menu show. custom context menu created dynamically based on data retrieved service. if piece of data changes menu while have context menu open, visible menu not change. ok. however when go click on item in old, displayed menu - firefox crashes.. repeatable 80% of attempts. basically need stop updates happening while context menu shown, , restart updates when disappears. yet cannot trap mouse right click. any suggestions?? you can rely on http://livedocs.adobe.com/flex/2/langref/flash/ui/contextmenu.html#event:menuselect More discussions in Flex (Read Only) adobe

ineffecient to access arrays out of sequence

basically little observation made when accessing arrays out of sequence. i had inside isr, , affected performance worse. found pretty strange code little bit of isr. tried have array element 2 @ top (not important @ of course). code: [select]  for ( int x=0 ; x<4 ; x++ )  {    for ( int y=0 ; y<4 ; y++ )    {      int cx = x+1;      int cy = y+1;      int fivecy = 4 - y; // 5-cy      face[2][x][y] = cube[cx][fivecy][0]; // top (face 2)      face[0][x][y] = cube[5][cx][cy];      face[1][x][y] = cube[cx][0][cy];      face[3][x][y] = cube[0][cx][fivecy];      face[4][x][y] = cube[fivecy][5][5-cx];      face[5][x][y] = cube[cx][cy][5]; // bottom (face 5)    }  } putting in sequence made faster again. thought wouldn't matter, guess compiler optimizations when arrays accessed in sequence? i have since optimized isr ~40% latency, these 2 versions (array in sequence vs out-of-sequence), had latency of 53 timer2 clock cycles (86% latency) , (see...

from spec sheet looks output analog voltage between pins 1b , 2a.  so if that's true, connect each (1b , 2a) 2 different analog pins on arduino.  measure each , take difference.  if difference positive gyro being turned in 1 direction, if negative, it's being turned in opposite direction.  i don't know if magnitude reflects velocity, angular position or acceleration.   if wanting use it. i've gleamed spec sheet.  do not use power arduino.  give separate power supply. jim.

hi, i new arduino , programming in general.  i have got code uploaded arduino control functions of 2 servo motors, i.e. forward, backward, left , right..  i want use php code send data trigger these functions @ click of button web browser, have no idea how started.. also using wishield asynclabs connect pc, makes more confusing me assume html/php code need uploaded arduino use wishields wireless/webserver feature.. does have experience this?.. appreciate can it's driving me insane.   thanks. nur hi nur, as far know arduino not able run actual  php code. you either write interface on real webserver in php forwards commands arduino. commands forwarded interface on wishield, or serial interface. or write pages on arduino. i'm not aware of possibilities of wishield. if has built in webserver, you'll have figure out if webserver can interface code. if doesn't have built in webserver, you'll have write simple webserver yourself. maybe can as...

i'm making project allows rgb led controlled through serial using c# program have written. this , example of string sending arduino c# app: 064,128,255 i use wrote code store in buffer read whole. code: [select] char* getstringfromserialdata() {  char charbuffer[11];  char newchar;  int index = 0;    while (serial.available() > 0)   {     if (index < 10)     {       newchar = serial.read();       charbuffer[index] = newchar;       index++;       charbuffer[index] = '\0';     }   }      return charbuffer; } it returns stored array of chars received through serial port. but need write method can take buffer, split substrings (rgb values extracted) , use them pwm value. is able me this, i've searched lot didn't find , i'm not acquainted pointers think plays part. any appreciated   one thing need careful charbuffer local variable. goes out of scope when getstringfromserialdata() function ends. returning point...

ADCH and ADCL - buffered?

if start , adc conversion, setting adsc bit in adcsra, , shortly thereafter (before conversion finished) read adcl , adch (in proper order), a) completed result previous conversion or b) half-completed result current conversion? this should help.  from s26.3 atmega 1280 datasheet... "if result left adjusted , no more 8-bit precision required, sufficient read adch. otherwise, adcl must read first, adch, ensure content of data registers belongs same conversion. once adcl read, adc access data registers is blocked. means if adcl has been read, , conversion completes before adch is read, neither register updated , result conversion lost. when adch read, adc access adch , adcl registers re-enabled."
