LED flashing light-emitting control routine simple. The program is practical works a Demo application templates directly from the main () function to start the preparation. In the main () function in front of the definition of the LED' s and pin GPIO port. In the main (), the first defines a variable ulClock, call the function in clockInit () was initialized to the current system clock frequency, the face of the Treasury function in the post-SysCtlDelay () call will use the variable. LED control points go to Step 3: Call Functions SysCtlPeriEnable () to enable the GPIO module LED is located, call the function GPIOPinTypeOut () where the LED configuration for the push-pull output GPIO pin, called GPIOPinWrite () is located on the LED pin GPIO write 0 and write 1 to achieve the effect of light-emitting LED flashes.
