Hi.
I am trying to read a file (ZIC2410_AES128_SnapV2.4.13.sfi), located at my Computer, trought the Arduino duemilanove RX Serial port, and then send it to the TX arduino port which is connected in RX port of a antenna module.
PC(TX) -> (RX)ARDUINO(TX) -> (RX)module
what i have found in some books and google is a txt file transfering examples, like this:
import processing.serial.*;
int mySwitch=0;
int counter=0;
String [] subtext;
Serial myPort;
void setup(){
//Create a switch that will control the frequency of text file reads.
//When mySwitch=1, the program is setup to read the text file.
//This is turned off when mySwitch = 0
mySwitch=1;
//Open the serial port for communication with the Arduino
//Make sure the COM port is correct
myPort = new Serial(this, "COM6", 9600);
myPort.bufferUntil('\n');
}
void draw() {
if (mySwitch>0){
/*The readData function can be found later in the code.
This is the call to read a CSV file on the computer hard-drive. */
readData("D:/mySensorData.txt");
/*The following switch prevents continuous reading of the text file, until
we are ready to read the file again. */
mySwitch=0;
}
/*Only send new data. This IF statement will allow new data to be sent to
the arduino. */
if(counter<subtext.length){
/* Write the next number to the Serial port and send it to the Arduino
There will be a delay of half a second before the command is
sent to turn the LED off : myPort.write('0'); */
myPort.write(subtext[counter]);
delay(500);
myPort.write('0');
delay(100);
//Increment the counter so that the next number is sent to the arduino.
counter++;
} else{
//If the text file has run out of numbers, then read the text file again in 5 seconds.
delay(5000);
mySwitch=1;
}
}
/* The following function will read from a CSV or TXT file */
void readData(String myFileName){
File file=new File(myFileName);
BufferedReader br=null;
try{
br=new BufferedReader(new FileReader(file));
String text=null;
/* keep reading each line until you get to the end of the file */
while((text=br.readLine())!=null){
/* Spilt each line up into bits and pieces using a comma as a separator */
subtext = splitTokens(text,",");
}
}catch(FileNotFoundException e){
e.printStackTrace();
}catch(IOException e){
e.printStackTrace();
}finally{
try {
if (br != null){
br.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
I know C language and java, but i dont know much about arduino programming stuff.
could you help me with it please?
thanks.
