THIS IS MY FIRST POST SO GO EASY!
Quit shouting. We may be a bunch of grumpy old men, but we aren't deaf.
When I run the serial monitor on arduino I ask the user to put the in the price, pallet wieght, and weight of 1 item.
And the code for this looks like?
1. I want to save the data while its looping continuously
Save it where?
until the user has pressed R to reset the program.
And, what exactly does the Arduino DO when it gets an 'R'?
2. Next while its looping I want to make a real time monitoring graph of Items VS time on the side until the R button has been pressed.
So, 'R' is to be a toggle? Weigh -> Graph -> Weigh -> Graph?
Im quite new to processing, I know how to do this if the program is continously firing data in the serial monitor
Psst. The Processing forum is down the road a ways.
If you are running Processing, the Serial Monitor can not be running (on Windows, anyway), so the Arduino isn't "continously firing data in the serial monitor".
How can you make a "real time graph" if you aren't getting real time data?
But my case is different as you have to wait for the user to type in the values and then the vales are displayed and then the loop beings.
I don't have to wait for your user to do anything. I don't understand how the "loop beings".
Also you have 3 differnt values coming in, Stock Value, Orignal weight, Items placed.
Which of these values do you want to store and later graph?
3. Is there anyway to control the serial monitor in processsing console
Absolutely none at all, since they can't be running at the same time.
Of course, I think you are using "serial monitor" where you mean "serial port", since the Serial Monitor is an application that listens to and talks to the serial port. It's just a happy fact that the Arduino is on the other end of the serial port.
