hi all,
i used the code for both Arduino and processing from the link below.
i am using GY_521 module and tried to see the data on processing. although i can read data on the serial montor i see alot of worries as below.
the problem kicks in when i use processing, when i hit run a big gray window open but thing else and an error shown on the console says
arduino worrings :

thank you all
