Well, did someone succeeded to disable the backlight ?
As per the FEX file, it should be driven by
which is linked to GPIO 56 Copy the Code
- lcd_bl_en = port:PH08<1><0><default><1>
But I can't drive the backlight :
don't do anything Copy the Code
- cd /sys/class/gpio/
- echo 56 > export
- cd gpio56/
- echo out > direction
- echo 0 > value
As per the same FEX file, the LCD pwm is driven by
so GPIO 57 Copy the Code
And this time is worked ... but only to switch the display on and off.
As it's labeled PWM, it is possible to change the light intensity ?
