First of all thanks for the willingness to help,

I am developing for my bachelor thesis, and infokiosk (with touch-screen) system which will provide services to the students of my department in...

Hello!

I would like some help in two things!
I have some experience in programming microcontrollers with c but i've never set a compiler for windows applications.

1) So do you know where i...

No, i am afraid you didn't understand what i mean.

I will set a simple task.

----------------------------
I have 10 variables.
From
number_0 = "blah..blah"
to...
number_9 = "another...

i think it is better to give you the some code to see what i mean.


these are two arrays

number_0[5][27]
number_1[5][27]

i didnot give you the content of the arrays because it was too big.

The problem is that i want to make my code smaller in bytes. So the if clauses do not offer me something better than case. I think that the cases are more efficient than the if clauses.

Anyway,
...

Hello,
i want a little help to make my code more efficient cause i work on an embedded system and i exceeded my rom capacity.

I have an int.
a=3 for ex.

I want for each a to call one array.
...

sorry i am blind,

it's ok. Thanks!

I have this code

------------------------------------------------------------
unsigned int digit0, digit1, velocity = 314;

char buffer[11];
sprintf(buffer, "%u", velocity);

digit0 =...

I am trying to do this.


sprintf(*velocity1, "%.1velocity", velocity);

So as to get the first character of the integer velocity and set it as the integer but it doesn't work. I found...

Thanks for the help salem but,

could you be a little bit more specific? The problem is that i use Keil(for embedded systems) compiler and i cannot see the result so easily.

Where can i find a...

I have an integer
for ex.
unsigned int a =120

1)How can i parse the digits of the integers seperately.
so as to have three integers.

b=1
c=2
d=0

Hello,

I am developing a multimedia application with which i want to make a telephone application via a infokiosk. So, i want from the multimedia application to call a program(propably in c) which...

ok, that is what i had done.

I just thought that it would be more efficient if i could know them without having stored them in the first row.

Thanks!

Ok, i redesigned it from the scratch and everything is ok.

I needed the 2-dimensional arrays for this reason.

I am displaying pictures like this in the image in a graphic lcd. So i take the...

i don't think so. xdata is saying that it wil be stored in the outside memory of the microcontroller.
I am working on an embedded system.

I tried to redesign it, there is not problem in debugging but there are a lot of errors in linking. The problems are saying:

ERROR 104: MULTIPLE PUBLIC DEFINITIONS
WARNING L16: UNCALLED SEGMENT,...

ok, sorry

i didn't know it.

but i want to use the display1 function several times with different arrays to import and different array dimensions.

What can i do about this?

What is wrong with this code?

It says that when i set
int x = myarray[0][0];
that there is no array(Specific subscript on non array or too many dimensions)


#include <reg52.h>
#include...

ok

Thanks a lot!

Ok with the integers.

But now with the array,

First of all there is no relationship between the array and the integers and i will not work with pointers.

I have in my lib.h file an array...

Hello!
I have a question to make. As i see if i want to load a byte in a function the code is

void name(uchar dbyte) {
...
}

But, i want to pass 2 integers (x,y coordinations) and an array...

How can i point with a for loop into a two-dimensional array and get it's value??

for(i=0; i<=15; i++){
//do nothing
}

How many processor cycles is this delay?
Is there a more efficient way to create a delay in my embedded system?

2) I want a delay of 1000 ns. My...

Hello,
I am trying to send some volts to my databus and i meter them.
The program is following.

#include <reg51.h>
#define XBYTE ((unsigned char volatile xdata*) 0)


void main(void) {
