Passing An Array... (Read 375 times)

Passing An Array...
Apr 2nd, 2009, 8:50pm  
Hi..!!

Can anyone help me please

i have made a motor speed control system using my HC11 as a school project, i also plotted my output response in excel and i got to say it was pretty good. i am now planning to have a processing applet which would plot the o/p response in "real-time"

Note: i have an array of 3 numbers that could go up to 1000dec each therefore, 2bytes each. my problem is not sending it out to processing but rather receiving it with processing. the string starts with a 0x0A(carr return) and then 6 bytes. anyone knows of a way that i can receive the 6 bytes plus 1sync byte and then separate them into 3 numbers(int).

i would appreciate any help i can get.. i have high hopes..

Thanks,
Swalehm

It should be quite easy:
Code:

byte[] data;
//recieve data here, I'm not an expert in that bit...

int a,b,c;

if(data[0]==0x0A) //check the data is starting right
{
  //if data is most significant byte first:
  a=(data[1]<<8)+data[2];
  // else
  a=data[1]+(data[2]<<8);

  b=(data[3]<<8)+data[4]; //MSB first, change as above...
//etc..
}
