How to make a cursor?

Thomas · June 16, 2006, 3:28pm

Hallo!

I need some input for programming.

I want to write a routine for editing same valus, the midi events of a button or poti.

A button has 4 midibytes (controller command, value1, valueOn, valueOff, type)

(if you now the PC1600 from peavey you’ll know what I mean)

it’s looking like this on the display (T==toggle):

old: BE017F01T

new: BE017F01T

Now I want to add a cursor, like

old: BE017F01T

new: BE017F01T

-

(indicating that you edit the lower nipple of the second midi byte)

My current solution is:

old: BE017F01T

new: BE0>1<7F01T

But this looks ugly.

Any Ideas?

Hi Thomas,

Maybe this helps:

//set edit cursor

MIOS_LCD_CursorSet(position_to_set_cursor);

MIOS_LCD_Cmd(0x0E);

//hide cursor

MIOS_LCD_Cmd(0x0C);

for more commands for a HD44780 display see:

Thanks, I will try it. I’ve overseen the MIOS_LCD_Cmd function.

does someone know how to make this cursor at the good position ??? it appears on the 4th line (adress 0xc0) on a 4x20 LCD

i can edit the EditBuffer but the cursor don’t want to move :getlost:
