STK6005

A blinking effect will appear in the character if a bit 7 Char index is set to 1. The foreground and

background color is mapped to one of 16 sets of the color pallet. Each set of color pallet is in 24 bits of

true color. The following diagram shows the architecture of STK6005 OSD.

To Set a Character and an Attribute

For a char displayed on location (X, Y) of OSD window, the converting formula of the Char / Attribute

memory address is shown as follows:

Memory Address = Y * Width + X

X indicates the horizontal position of the Char in OSD window (in unit of Char)

Y indicates the vertical position of the Char in OSD window (in unit of Char)

Width explains the horizontal duration of OSD window (in unit of Char)

Two sequences can be applied to write the Char / Attribute contents:

You can write Char / Attribute separately by setting CharOnly = 1. The memory address will

automatically increase 1 after you write a Char or an Attribute, and then you can write a next Char or an

Attribute content. Or you can write Char / Attribute pairs by setting CharOnly = 0. The memory

address will not automatically increase 1 until an Attribute is written in. The steps to set Char and

Attribute are shown as follows:

1. Calculate and set a memory address (write uWrAdr).

2. Write a Char index (write uWrChr). If CharOnly = 1, go to step 4.

3. Write an Attribute index (write uWrAttr).

4. Go to step 2 for continuing to set a next position of Char.

Go to step 1 to recalculate a new address or stop the procedure.
