Have search our forum & have not found what I am looking for.
This could be a long shot in dark.
Using the HD44780, 20x4 LCD display in 4 bits mode.
Is there any function to blink or flash or invert a word like "Hello World". (Positive to Negative at about 500mS rate)
I know about the Cursor On & Off method.
Can this be done ?
Any pointers, links, suggestions or snippet of asm code, would be appreciated.
