my lcd display is done, i used microblaze, i can write there any data with size of 16x2.
the main problem is, my data is bigger then line size at screen. i Read about do some automatic shift to the data till would be possible to read all the line...BUT, I tougth would be possible with hardware description control the rotary button, and with this control each line i want, till read it all..
So what i said before it was, how can i control(if possible) the processor(*.c) with the button(*.vhdl)?
thks
