Flickering console in eGUI

Thommi_Tulpe — Mon, 14 May 2012 18:47:11 GMT

Hello,

i am using a console on the LCD (TWR-LCD).

I am useng a TWR-K60N512 with TWR-LCD.

I am using a console in one screen. The screen is flickering. I think it is because the

D4D_Poll() Funktion witch redraws the screen periodictly.

(D4D_RedrawScreen(pScreen); in D4D_Poll)

Is it possibe to redraw the screen only when something is changed ?

This is when I put a character or string to the console or the flashing cursor.

Or is it possible only to redraw what is change and not the hole screen ?

Best Regards

Thommi

Problem solved

I changed the TWR-LCD and everything is O.K.

Do you mean you physically changed it?

We had a similar issue with the TWR-PIM-41WVGA, but it simply turned out that the regulator on the K70 was at it's limits.

OK when powered from the elevator...
