cols parameter ignored

[regdomain]

Why cols parameter is just ignored in void LiquidCrystal_I2C::begin(uint8_t cols, uint8_t lines, uint8_t dotsize)? The cols variable is never used in the code.

Subsequently lcd.write() which should print characters in a row goes beyond the capacity of your display. Looks like it uses an internal buffer which is 40 characters per row regardless of what type of display you are actually using.
