Honored ContributorI cant find any mistake but my compiler says its a mistake
Dear all,
Please help me out her. counter <= counter + '1'; this is my instruction this is my error. So what is the mistake in it? Error (10327): VHDL error at led_blink.vhd(24): can't determine definition of operator ""+"" -- found 0 possible definitions11 Replies
Altera_ForumThats because you havent defined a "+" function, or havent included a package that defines a "+" function that can add together whatever the type of counter is and '1' (which I assume you expect to be a std_logic)
Why not include all the code, not just a single line, as it all depends on what libraries you have included and what type counter is.
