Hello

I am working on a remote control for my arduino project.
Simply I want to send a serial command from processing to my arduino.
My arduino is connected via a Serial-Bluetooth (HC-05) to the computer, which has installed the dirvers automatically, andd assigned it to a COM port. Using Putty or any other ordinary terminal software, the communiction works without any problems. But In Processing it does work about 5% of the time, I want to use it.
If it doesnt work, I need to restart my programm, and maybe it will work - one it works it works as long as the program is open.
I have checked the RXTX library version and already replaced with the arduino ones.
When I change to another serial port in porcessing than the Bluetooth serial port, it works like a charm.
I have no clue, why it simply wont work with the bluetooth serial com port.
I hope you guys will be able to help my out...
thx in advance

Hello

I am working on a image to data converter for my LED-POV project, that reads in an .bmp file, and reads the colors on specified positions in the image, and warps them into a file.

But i´m stuck at the very beginning, where is simply want to display the calcuated lookup positions on the window with the set() function. But it only draws the first pixel (should be around 4096 individual pixels) to the screen. the position values are claculated properly - i have checked that with two lines, outside my loops.

As I understood in the reference, it should be possible to use the set() function in a  for loop, and all individual pixels will be drawn after the loop is finshed.

anyway here is the relevant code:

1. void draw() {
     //frameRate(25);                                    //reduce framerate
     //background(255);
     //image(clayer1, layerposx, layerposy);
     for(int framepos = 0; framepos < 256;) {
       calc_angle();
       for(int ledpos = 0; ledpos < 16;) {
         calc_hyp();
         calc_pos();
         //pixcol = get(position_x, position_y);
         color black = color(0);
         loadPixels();
         pixels[position_y*900+position_x] = #000000;
         updatePixels();
         //set(position_x, position_y, black);
         //stroke(255,0,0);
         //line(0, position_y, 900, position_y);
         //stroke(255,0,0);
         //line(position_x, 0, position_x, 626);
         ledpos++;
       }
       framepos++;
     }
   }

I thank you guys in advance! I am sure that there is just a rediculus problem, but i cant find it ...
