REMARK:

1)MCU initialize.

2)Is the EEprom blank?

3)Program the EEprom by default values.

4)Get the PWM value of brightness from EEprom.

5)Is the power key pressed?

6)Clear all global flags.

7)Are the AUTO and SELECT keys pressed?

8)Enter factory mode.

9)Save the power key status into EEprom. Turn on the LED and set it to green color. Scalar initialize.

10)In standby mode?

11)Update the lifetime of back light.

12)Check the analog port, are they’re any signals coming?

13)Does the scalar send out an interrupt request?

14)Wake up the scalar.

15)Are there any signals coming from analog port?

16)Display "No connection Check Signal Cable" 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?
