1)MCU initialize.

2)Is the eeprom blank?

3)Program the eeprom by default values.

4)Get the PWM value of brightness from eeprom. Check the pin PANEL1 and PANEL2 to tell which panel to get with it.

5)Is the power key pressed?

6)Clear all global flags.

7)Are the AUTO and SELECT keys pressed?

8)Enter factory mode.

9)Saving the power key status into eeprom. Turn on the LED and set it to green color. Scalar initializes.

10)In standby mode?

11)Update the lifetime of back light.

12)Check the analog and digital port, are there any signals coming?

13)Does the scalar send out a interrupt request?

14)Wake up the scalar.

15)Are there any signals coming from analog or digital port?

16)Display " No Input Signal " message. And go into standby mode after the message disappear.

17)Program the scalar to be able to show the coming mode.

18)Process the OSD display.

19)Read the keyboard. Is the power key pressed?
