About the problem found years ago on the setCursor command in the row 3 and 4 on 1604 LCD I have modify the file LiquidCrystal_I2C.cpp
at the line: 143 as follow:
void LiquidCrystal_I2C::setCursor(uint8_t col, uint8_t row){
int row_offsets[] = { 0x00, 0x40, 0x14, 0x54 };
if ( row > _numlines ) {
row = _numlines-1; // we count rows starting w/0
}
if ((row > 1) && (_cols < 20)) {
col -= 4;
}
command(LCD_SETDDRAMADDR | (col + row_offsets[row]));
}
adding these two lines of code I solved the colum problem on row 3 & 4 of 1604LCD.
I have to verify if the 2004 LCD works good also.
If there are better solution to avoid this problem please let me informed.
Kind Regards.
