Arduino write data - serial

I need to send now line by line gcode from txt file and wait untill position is reached before sending next line

@glv

The Processing website has resources (tutorials, references and examples) as well.

I would start with reading the text file and extracting a line as a string.
Check out the data tutorial and take a look at the related references.

I took the simple example from the data tutorial and was able to send the strings to the Arduino.
I sent the string received by the Arduino back to Processing to display it; I usually have a second serial port to monitor data but it (serial to USB adaptor) was not available at the moment.

It helps to be able to monitor the data received on the Arduino.

• another serial port with a USB to serial adaptor
• LCD
• network
• other

Note:
I did add a myPort.write('\n'); to terminate the string on the Processing side.
Arduino side:
Serial.readStringUntil() - Arduino Reference

Have fun!
