first, I am a new user of LM4F120H5QR....I have very less knowledge about it....
I am using the sensor name "Ultrasonic range finder"....I have to give it the Trigger pulse of duration 10us and as response it gives me ECHO signal in form of "continuous high pulse".....
I want to take the input(ECHO) from my Ultra sonic range finder and give it to GPIO pin and want to measure the ON period of that Echo signal....
how to take input at a GPIO Pin??? and how can I measure the HIGH Pulse duration.....???
Please help...
thanx in advance....
