I am working on 4 bit LCDisply. I want difference between thesetwo instructions : lcd_com( )& lcd_puts( ). Please give the exact difference between them with their exact defination.
"i got this functon from lcd 4 bit c code in google search." That is absolutely no help to anyone whatsoever! You have the code in front of you, and you know where it came from - so look at the code, and look at the supporting information for it. If it doesn't have supporting information, keep on goggling til you find something that is properly explained! Nobody else has any idea what code you're talking about, so can't possibly comment on it!
