Hello! I use LCD 4x20 from Microtips in 4 bit mode for my application. But i have some troubles.
Lines 2 and 4 not accessible in lcd. And i don't know why. When i write to the line 2 - nothing happens. When i write to the 4th string - text appears at th beginning of the first line.
Lines 1 and 3 works correctly.
Have you got any idea about this?

lcd built on KS0066 driver and this is my init sequence:

delay(200mks);
DATA=0x020;
EN=TRUE;
EN=FALSE;
delay(2mks);

DATA=0x020;
EN=TRUE;
EN=FALSE;
delay(2mks);
lcdWriteCommand(0x028);
delay(50mks);

lcdWriteCommand(0x08);
delay(2ms);
lcdWriteCommand(0x0C);
delay(2ms);
lcdWriteCommand(0x01);
delay(2ms);

lcdWriteCommand(0x06);
delay(10mks);


Thanks for assistance
Igor
