Please help me on this.. Its very urgent.. I have an Arduino Mega ADK with USB port built in based on MAX3421E and also have a USB GPS Dongle (Baud Rate 9600) that uses CP2102 USB to UART bridge. I want to connect that GPS dongle with USB port in Mega ADK board and want to read the GPS data and display the same in serial monitor..
Actually I want to make a GPS clock and hence to display it on LED matrix for a study project. If I use that GPS dongle with necessary drivers on PC I can display the time through various applications. But it is not easy to read the GPS time data from USB type GPS dongle through Arduino Mega ADK without proper driver program: even with USB Host Shield Library... I am new to arduino....
So this is a study/exercise for your school? you say it's super urgent, meaning you need to hand over the result of your work soon and you have done nothing and hope someone will do this for you? Did I get that right? That usually don't fly too well here...
Do you have the data sheet of your GPS?
Do you know how data is sent on "USB"?
What have you read on arduino programming?
What have you tested? there is tons of code already dealing with GPS...
You Do need to do your homework and help yourself get there... It won't happen by magic...
