I'm using flex lcd 16x2 driver in my project. is it possible to use this driver to make a certain character blink or highlight?.

Those features are a dependent on the LCD you have,not the driver.Consult the datasheet for your LCD.If it lists them there will be a 'command' or 'control' sequence to enable/disable those features. It is easy to add those commands into the flex_lcd driver.Be sure to make a copy the original driver,naming it 'myLCDdriver' or similar and modify that NOt the original driver!

There is a function in the Code Library to turn the hardware LCD cursor
on/off and to turn cursor blinking on/off. It works with the Flex driver:

I'm not impressed
That datasheet is terrible ! All the 'good' details are missing.
Seems to be dased on the KS0066 LCD module...
You should google 'ks0066 LCD' and see if you can find a COMPLETE data sheet with ALL the commands and functions.

You could re-position the cursor, using the lcd_gotoxy() function.
Then enable blinking using the function in the previously posted link.

To do it without using the above method takes a special lcd driver
which is written for that purpose.
