- Guess constructor for i2c LCD backpack
NOTE/WARNING: Guessing the i2c constructor is not really a
good thing since it could damage the hardware. Use with caution!
Do not leave things with an incorrect guess for too long.
i.e. advance to the next guess as soon as possible
when the guess in incorrect.
If the guess is correct, the constructor will show up
on the LCD.<Press or click [Send] to Continue>
I did focus to text box an cursor is blinking but nothing happens. Nor does clicking "send"
But now i tried to add a character on the serial monitor. So i just added "-" and hit enter and it works! So it does not accept empty line.
About backlight.
The jumper seems to cut off positive pin from the backlight. So i could just analogWrite to that pin. Will try that later!
edit: Yeah, pwm works. Wrote 20 for backlight and its totally enough.
Someone could suggest me a i2c backpack that can do backlight control too? So i would not need the extra cable for backlight.
