I have builded a project with an OP77B.
But I have a problem with UP and DOWN keys.
I don't know if it is problem but I am sure that it is very strange for me.
I have 5 screens (setup, setup_1, setup_2, setup_3, setup_4) and 1 main screen (main_menu). Totally 6 screens.
At "main_menu" screen the up and Down keys has no function and with F2 key activated the screen "setup".
At "setup" the up key has no function and the down key activates the screen "setup_1".
At "setup_1" the up key activtes the screen "setup" and the down key activates the screen "setup_2" and so on and so forth.
At every screen pressing twice the ESC key goes at "main_menu" screen.
This is the philosophy but in reallity and in simulator also the things are different. Running the project and being at "main_menu" screen if I press the up or down key I have no function..right. Pressing the F2 key goes to "setup" sreen..pressing the down key goes to "setup_1" screen....pressing the down key goes to "setup_2" screen...pressing up key goes to "setup_1" key and pressing ESC key goes to "main_menu" screen. Now pressing the down key normally shouldn't go anywhere becouse at this screen the keys up and down has no function. But pressing the down key goes to "setup_1" screen for no reason at all. Pressing ESC key goes to main_menu and pressing the down key again goes to the last screen. I think that something happens with reach margins and scollable area but I don't know what...
Thanks a lot in advance for any help.
