hi everyone..
i need ur help to help me solve the problem of plotting the serial data into zedgprah c# function..i can read the data from the arduino and save it into a variable...and im using backgroundworker function to do the asynchronous job.my problem is that..all the data i got from arduino is not displayed on the zedgraph.i want to do the realtime monitoring system

how to seperate the the thread from UI, PaulS?sorry for asking as im new in c#...from the search in the tutorial, it seems that i have to use the backgroundworker code..how i use that in proper manner?

this is my snippet of coding for arduino..

Code:

float rate, waterlevel,longitude,latitude;
...if (latitude== 3.8463 && longitude==103.3059)
{serial.print("latitude:");
serial.println(latitude,4);
serial.print("longitude:");
serial.println(longitude,4);

why i cannot pun the value of latitude and longitude into the label on the winform?

it is not working for serial part..n the latlong transmitted cannot be displayed in the label in c# winform.

you are right ,jjspierx

im just receiving the latitude sent by the transmitter and display on GUI.does the code for dispalying the latlong making any sense?

hi PaulS, attached is my code that will received the arduino data.

the result of the code is appeared in the serial monitor of the arduino and on the console application...however the data is not appeared on the windows form? is there any wrong with my code?

yes.i have extracted the file..

there's an error " Couldn't find input file"Properties\Resources.resx.what thats mean?

yes.n i have take a look on the threading..when i click on the button..it says "The port is already open". However there is no data appeared on the WPF.it appeared in the console application and arduino serial monitor but not in the WPF C# application.

PaulS, my problem now, the serialport is open..however the data cannnot be uploaded in the WPF?
if every function im doing the threading part..is it works to received the data in synchronous manner?
im handle the serial port class in one threads and the data in another threads..

that's means it will not read the data into gui?

i am able to receive the da ta on the arduino because i have check it using the SerialMonitor of the arduino.however, i cannot get those data received to be transferred to  my GUI using c#.nothing appeared on the GUI side.

so the coding for writeline and readline cannot read the data from arduino?

arduino uno r3 compatible.
