I am trying to upload my program to communicate with an GPS module. When i press upload, the software says: "uploading to I/O board". Under it, it says that I use 5502 Bytes of 258048 maximum. The Leds show some activity.
But at this point it freezes. Only the Tx LED shows an occasional blink.
When I upload the example program HelloWorld.pde from the LiquidCrystal Library, it uploads and it works alright.
When my partner uploads the GPS program, it works alright.
I have windows 7, 64 bits. I have an Arduino Mega 2560.
My partner also works on windows 7.
Thanks in advance.
