Hi,
I have a question about the LCD 16x2 i2C.
When I start the printer the LCD has the backlight on, but when the printer starts to work and has connection the LCD backlight turns off automatically.
I want the backlight on all the time. Do you know how to di it?
Thank you so much,

When it was a personal project I had turned LCD backlight off.
If you have time to try new builds, I will try turn it on.

Yes I have time.

Hi Shahin,
Can I also register my interest in an option to turn on the backlight.
I purchased a 16x2 with an orange backlight for future proofing and to look nice in conjunction with my machines amber (orange) perspex cover.
Meanwhile, does anyone have any suggestions for manually hardwiring the LCD or the iic/i2c adapter, so that the backlight remains on?
Many thanks,

I have update the beta version. Let me know if it is working now.

Perfect...The LED Backlight is working for me now in the latest Beta version.
For the record; I'm using LCD Display LCM1602 with a HD44780 controller/driver and a piggy backed IIC/I2C Serial 1602 2004 LCD Interface Adapter Board Module( PCF8574T)
If anyone wants to hard-wire their backlight instead of trying the latest Beta software, then you can simply connect Pin 1 (LED-K) to Pin 16 (Vss Ground Logic) on the LCD
Many thanks Shahin for implementing this in software, which is a much better solution of course.
