Single lights left to do right, the hardware circuit as shown, eight light-emitting diode L1 - L8 were connected to the MCU P1.0 - P1.7 interface on when the output "0", the LED lights, at the beginning P1.0 → P1.1 → P1.2 → P1.3 → ┅ → P1.7 → P1.6 → ┅ → P1.0 bright, repeat the cycle.

　　The "SCM system" area of ​​P1.0 - P1.7 with 8-core cable connected to the "Eight LEDs indicate module" area of ​​L1 - L8 on the port requirements: P1.0 corresponds to L1, P1.1 corresponding to the L2, ... ... P1.7 corresponds L8.
