[rohan]

Hi !!

I want to make wireless notice board.I m not able to receive data on lcd.please tell me my mistake in this program.Thanks in advance.

#include <LiquidCrystal.h>
#include <SoftwareSerial.h>

SoftwareSerial BTSerial(2,3);//rx,tx

char cmd_arr[40];
LiquidCrystal lcd(4,5,6,8,9,10);
//*************************************************
void serial_get_command()
{
  int i;
  char inchar=0;
  int cmd_count=0;
  for(i=0;i<=31;i++){
    cmd_arr=' ';
  }
  if(Serial.available() > 0)
  {
    inchar = Serial.read();
 
    if(inchar == '<')
    {
      cmd_count=0;
      while(inchar != '>' && cmd_count<33)
      {
        if(Serial.available() > 0)
        {
          inchar = Serial.read();
          cmd_arr[cmd_count++] = inchar;
          cmd_arr[cmd_count] = ' ';
        }        
      }
      if(inchar == '>')
      {
        cmd_arr[cmd_count-1] = ' ';
        Serial.print("Cmd received : ");Serial.println(cmd_arr);
        Serial.print("OK");
        lcd.clear();
        lcd.setCursor(0, 0);
        for(i=0;i<=15;i++){
          lcd.print(cmd_arr);
        }
        lcd.setCursor(0, 1);
        for(i=16;i<=31;i++){
          lcd.print(cmd_arr);
        }
        //serial_process_command();
      }
    }
  }
}
//*************************************************
void setup()
{
  BTSerial.begin(9600);  
  Serial.begin(9600);
  Serial.println("System Started!");
  lcd.begin(16, 2);
  lcd.print("Bluetooth Based ");
  lcd.setCursor(0, 1);
  lcd.print("    Notice Board");
  delay(2500);
  lcd.clear();

}
//*************************************************
void loop()
{
  serial_get_command();
 
}

Check the setup function. It is not called??? or else make the setup codes away from the functions.
