Hi,
I'm trying to interface a DL-100 load cell with an arduino UNO. I'm very new to coding and am unfamiliar with Serial and Serial 2 in the example code they provided on the website.
Here is the tutorial and the example code they gave.
It won't compile and I think it's because I have an UNO and not a MEGA. If anyone can help me and tell me how to get this to work on an UNO that would be much appreciated.
If this is not possible without a MEGA, I have the funds to purchase one so let me know if that's my best option.
Thanks so much!
/*
This program continuously reads weights from a Loadstar Sensors'
DI-100 digital load cell interface connected to a load cell.
The DI-100 is powered by the Arduino and the Tx/Rx pins are connected to
TX2 and RX2 of the Arduino Mega 2560 board.

int isPolling=0; //are we continuosly reading weights?
void setup()
{
// start serial port at 9600 bps for communicating with the Arduino via Serial/USB to PC:
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect.
}
Serial.print("Connected to PC\n");
// start serial port 2 at 9600 bps for communicating with iLoad Series Serial Sensor or DI-100 Serial Interface:

}
Serial.print("Connected to Sensor\n");
Serial2.write("TARE\r"); //zero the sensor
delay(5000);//wait for 5 seconds before polling
isPolling=1; //start polling
Serial2.write("W\r"); //send one command to read the weight, after the weight is
//read in the event loop, another command to read the weight is sent
}
void loop()
{

void serialEvent2() {
char c=char(Serial2.read());
Serial.print(c);
if (isPolling==1 && c=='\n') {
//we just finished reading a weight
//read the weight again.
Serial2.write("W\r");
}
