I want take data upto 10 kb from one device serially and send that data to pc serially using arduino is it possible?

Projects General Guidance
1

i use below code . In simulation its working properly and able to send large data. but is it work in hardware? . I am using arduino uno r3.

#define SERIAL_BUFFER_SIZE 256
#include <LiquidCrystal.h>

// initialize the library by associating any needed LCD interface pin
// with the arduino pin number it is connected to
const int rs = 12, en = 11, d4 = 5, d5 = 4, d6 = 3, d7 = 2;
LiquidCrystal lcd(rs, en, d4, d5, d6, d7);

void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
lcd.begin(16, 2);
Serial.println("Data & Time, Mesurement");

}

void loop() {
// put your main code here, to run repeatedly:
while(Serial.available()==0);

char val = Serial.read();
Serial.write(val);
lcd.write(val);

//Serial.print(",");
// Serial.println();

}

can i send large amount of data upto 10kb usnig this code??
#define SERIAL_BUFFER_SIZE 256
#include <LiquidCrystal.h>

// initialize the library by associating any needed LCD interface pin
// with the arduino pin number it is connected to
const int rs = 12, en = 11, d4 = 5, d5 = 4, d6 = 3, d7 = 2;
LiquidCrystal lcd(rs, en, d4, d5, d6, d7);

void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
lcd.begin(16, 2);
Serial.println("Data & Time, Mesurement");

}

void loop() {
// put your main code here, to run repeatedly:
while(Serial.available()==0);

char val = Serial.read();
Serial.write(val);
lcd.write(val);

//Serial.print(",");
// Serial.println();

}

You can send as much data as you like through a serial port, but not with that code, it won't work.

See Serial Input Basics - updated for advice on using serial.

If it’s static data, you’re limited by the amount of FLASH, if it’s stored in variables - you’re limited by RAM…
if it’s generated programmatically, or off chip (SD card etc, or network), effectively no limit.

Do you want to 'read' the data into the Arduino (UNO ?)
OR
Send the data from the Arduino.

To send just use
Serial.print(...) as often as you need.

See Arduino Serial I/O for the Real World for problems that can arise sending / receiving lots of data while trying to do other things.

I tried this solution but I don't get any output

You may find that you're limited by the LCD write rate.

lcd is optional want only data in pc. if i done hardware also it will work??

sorry, i am new on forum.

As stated in reply #3, you can send as much data as you want, serially to a PC.

Of course not. Read reply #3 and follow the advice (link) given.
