Hello cam.
What stamp have you got? exactly what version?
I have the 1.6 version and the commands to send the stamp are :
Serial.begin(9600);
for continuos readings : Serial.print("read()c");
Serial.print(13,BYTE);
for only one read is: Serial.print("read()");
Serial.print(13,BYTE);
if you have got the last version 2.0
Serial.begin(38400)
for contiunuos readings :Serial.print("R");
Serial.print(13,BYTE);
for single read : Serial.print("R");
Serial.print(13,BYTE);
You can first try with this code I: (do not use the NewsSoftserial
library)
void setup()
{
Serial.begin(9600);
}
void loop()
{
char inData_pH[24];
int index =0;
float pH_val = 0.0;
Serial.println("read(26.0)c");
delay(1000);
while (Serial.available() > 0 && index < 24)
{
inData_pH[index] = Serial.read();
index++;
inData_pH[index] = '\0';
}
Serial.print("Sensor output: [");
Serial.print(inData_pH); Serial.println("]");
// pH_val = atof(inData_pH);
// Serial.println(pH_val);
}
first load up the code to Arduino with the Stamp 2.disconnected
and when load it is done , unplegged the usb from Arduino.
After connect the Stamp to arduino on 0,1 pins (RX0,TX0).
and connect the usb to arduino.
This way first you can see if the Stamp work or not work.
good look.
