Software Hints
9.1.1
Programming Recommendations
1. If necessary write a new allocation just before the RAM reset.
2. If necessary write a new allocation at any time but take care of the window display.
3. When resetting the RAM and writing in it just after, write in the RAM respecting the same order
as the reset: from the first to the last reset window, from the first window address (row 0, col 0)
to the last, incrementing columns, then rows, then windows.
4. Define the window horizontal size prior to writing character and color codes in RAM.
HSWI is used to compute the RAM address.
9.1.2
Examples of Programming
Hard reset at power-up
(following a power-up)
1. Write Window 0 registers to set the OSD parameters: write
VCO[1:0], horizontal resolution and vertical height of characters,
the position of reference,
the allocations if they are incorrect
(by default: 320 characters for window 1, 128 characters for each of the others windows)
the windows position and size,
the color-boxes that will be used.
2. Write the character codes for each window to display.
3. Write the color-box data for each window to display.
4. Write the enable of windows: ENWi = 1 then ENOSD=1.
Change of position & size of 1 window (ex. window 3) without disable of window
1. Write new position and sizes.
2. Write new characters in the RAM.
Re-allocation, reset, and writing new characters in windows
1. Disable windows.
2. Write new allocations.
3. Reset the windows.
4. Write new positions and sizes in control registers.
5. Write new color-boxes.
6. Write new characters and color codes.
7. Enable windows.
