LCD Backlight Control Connector
The board provides one 1x4Pin wafer LCD backlight control connector (Pitch:
2.0mm); the pin definitions are as follows:
Pin
Signal Name
1 VCC_LCDBKLT
2 LCD_BKLTCTL
3 LCD_BKLTEN
LCDB1
4 GND
Note: VCC_LCDBKLT -------+12VBacklight Power (The current is limited below
1A);
LCD_BKLTCTL---Backlight Control (The signal is output as PWM signal via
CPU directly; the voltage amplitude is 0V-3.3V while the duty cycle is between
0% ~ 100%);
LCD_BKLTEN ---Backlight Enable, Active High. (The signal is output as
CMOS output via CPU directly; the voltage amplitude is 0V-3.3V).
