structuring libraries - accessing libraries from within libraries

hello, i bit confused on library selection procedure: first: - still using arduino 0023 because use chipkit max32 boards - running on windows 7 - base libraries can found in c:\...\mpide-0023-windows-20120903\hardware section - project can found in c:\users\...\documents\arduino - have library directory in c:\users\...\documents\arduino\libraries if build project, lets projecta, in c:\users\...\documents\arduino\projecta. in project use library, lets liba, in c:\users\...\documents\arduino\libraries\liba in last directory see liba.h , liba.cpp lets assume have second library, libb file libb.h , libb.cpp. we find them in c:\users\...\documents\arduino\libraries\libb now problem: assume want use libb in liba used in projecta projecta.h has line #include <liba.h> liba.h has line #include <libb.h> if compile projecta liba.h found receive "file not found" error on libb.h if put line #include <../libb/libb.h> liba.h receive errors on undefined functions ...

salve tutti, ho un problema con lcd 16x2 (un 1602a basato su hd44780) interfacciato ad una scheda uno e non ne vengo capo. il display si mostra come nell'immagine seguente. la foto è presa di sbieco e con contrasto al massimo perché si veda meglio la matrice praticamente manca la metà superiore della seconda riga. la uno serve mostrare le condizioni di funzionamento di un'interfaccia usb-i2s e funziona correttamente (nel senso che messaggi mostrati sono quelli che devono essere secondo la logica dello sketch). i collegamenti uno->lcd li ho ricontrollati più volte e sono tutti ok. l'alimentazione sono +5vdc in uscita dalla uno. la retroilluminazione prende sempre +5vdc con una 220r in serie, il contrasto si regola correttamente mediante il pot da 10k. la tabella dei collegamenti è: rs   e   db4  db5  db6  db7 7     6       5       4        3       2 rw su ...

problema con la gestione di file

robot movement problem need some help

kindly, have wheelchair robot controlled bio signals...the arduino receive signals sensor through analog pins , out  digital signal control movement of robot (right,left,forward or back)...my problem when subject sit out of wheelchair signal controlled arduino when subject sit on wheelchair signal become uncontrolled... use following code guide wheelchair movement... code: [select] const int u1=10; const int u2=10; int a[u1]; int b[u2]; int right = 3; int left = 6; int forward = 9; int = 11; int value1= 0; int min1=1023; int max1=0; int value2= 0; int min2=1023; int max2=0; int x = 1; int c1 = 10; void setup () {   serial.begin(9600);   pinmode(right, output);   pinmode(left, output);   pinmode(forward, output);   pinmode(back, output);   pinmode(13, output);   digitalwrite(13, high);   while (millis() < 5000) {     value1 = analogread(a8);     value2 = analogread(a12);     if (value1 > max1) { ...

Extension Problems

none of extension work after loading dw 8 on. followed direction for applying new extensions dw 8. suggestions. yea know write code why if don't have to.

How to read values greater than 255?

Image
hi, i started using i2c , want run continuous rotation motor speed implemented user through udp (this part have accomplished). the master 1 sending "slave" speed should go. however, trying write integer value greater 255 second arduino (i.e 1030). below snippet of master code: code: [select] int right = 0; int motorspeed = 0; ............. case 0x00: // motor turning right  right = 1024 - motorspeed; // 1024 reference point of motor there no speed above 1024 go left below go right.  wire.begintransmission(2);  wire.write (right);  wire.endtransmission();  break; below snippet of slave code: code: [select] while(wire.available())  {    int motorspeed = wire.read();    if (motorspeed == 0)    {      myservo.write (1024); //motor stopped    }    else    {      myservo.write(motorspeed); //write speed received    }  } thu...
