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 is adapted.
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. Scaler initialize.
10)In standby mode ?
11)Update the life time of back light.
12)Check the analog and digital port, are there any signals coming ?
13)Does the scaler send out a interrupt request ?
14)Wake up the scaler.
15)Are there any signals coming from analog or digital port ?
16)Display "No Signals" message. And go into standby mode after the message disappear.
17)Program the scaler to be able to show the coming mode.
18)Process the OSD display.
19)Read the keyboard. Is the power key pressed ?
