Hi,


I am suing processing 1.5 with XP 32bit and i want to do serial comm of uC using PIC16F877 with processing and tested that pic uC code in serial terminal window it is transferring 0xff and 0x02 with delay in between to see the color diff on processing window there is no error in both code but then also it is not changing window color why??

1. #include <htc.h>
2.  __CONFIG(LVP_OFF & BOREN_OFF & PWRTE_ON & WDTE_OFF & FOSC_HS);
3.  #define _XTAL_FREQ 20000000
4.   void  HSerinit(void), HseroutString(unsigned char* str), Hserout(unsigned char ch);
5.  void main(void)                        // program entry
6.  {
7.      TRISB=0x00;   
8.        // <- LOOK HERE.
9.  ADCON1 = 0x6;                    // Analogue off
10.  HSerinit();
11.  __delay_ms(150);
12. unsigned char ch=0;
13.  while(1)
14. {
15. ch=0xff ; 
16.    Hserout(ch);
17. __delay_ms(500);
18.  ch=0x02 ; 
19.    Hserout(ch);
20. __delay_ms(500);
21. }
22.  }            
23. void HSerinit()  
24.   {
25.  TRISC = 0x80;                    // TX was an input!    
26. SPBRG = 129;                    // 20Mhz xtal 9600 BAUD
27.     TXSTA = 0x24;                    // TXEN and BRGH
28.     RCSTA = 0x90;                    // SPEN and CREN  
29.   }
30.  void Hserout(unsigned char ch) 
31.    {   
32.  while(!TXIF);   
33.  TXREG = ch;    
34.     }      

1. import processing.serial.*;
2.  Serial port; float brightness = 00;
3.  void setup()
4. {
5.  size(1200, 600); //Set size of the window
6.   port = new Serial(this, "COM11", 9600); //change "COM11" to the usb port, you are using
7.   port.bufferUntil('\n'); //wait for a value to appear in the Serial monitor
8.   }
9.   void draw()
10.  {     background(0, 0, brightness);
11.  }
12. void serialEvent (Serial port)
13. {
14.  brightness = float(port.readStringUntil('\n'));
15.   }

HI,

I want to make window for making serial communication between pic-controller UART.
I am new to serial communication in Processing i have learned few things but no idea how to do??
so, just for now i want to make LED with Switch on processing to switch it on/off..
any suggestion please....


thanks

Hi again,

If i want to add background image then what to do for doing it??
I have seen reference but was not clear to me where and how to load it in data folder...

Hi,


I am new to programming of Processing and learning from reference i want help in writing text to screen :-

the font i want use can be any one from my control panel eg: 101! Cacti
but i have copy this to download folder of processing and changed

FFScala-32 to 101! Cacti but it does not work , please help..

1. PFont font; // The font must be located in the sketch's // "data" directory to load successfully font = loadFont("FFScala-32.vlw"); textFont(font); text("word", 15, 30); fill(0, 102, 153); text("word", 15, 60); fill(0, 102, 153, 51); text("word", 15, 90);
