Hello,

I am trying to start above mentioned display. I tried to write initialization code based on documents of the display. No success. I also searched internet (including this forum), and tried to write code, based on programs I've found. No success.

I am using 89S8253 and 4-bit connection. Below is the code I am using. I get blank display with two lines (obviously not proper initialized lcd). Does anyone have any suggestion or working code (preferrably in C)?

thank you and a happy new year to everyone!

delay (1500);

// 4-bit, font 5x8, duty??? ram??
lcd_code (0%11011010); delay (1000);

// SE: autoincrement on write, no inc. on read
lcd_code (0%01010010); delay (10);

// display off, set cursor and underline mode off
lcd_code (0x2F); delay (10);

// SU:
lcd_code (0x01); delay (100); // clear ram
lcd_code (0x03); delay (10); // cursor home, display start


lcd_code (0x3F);// display on, set cursor and underline on
delay (100);

return;
