|
* This routine initialises the Retina Z3 hardware, opens a
|
|
* text- or gfx-mode screen, depending on the the value of
|
|
* MonDef.DEP, and sets the cursor to position 0.
|
|
* It takes as arguments a pointer to the hardware-base
|
|
* address as it is denoted in the DevConf structure
|
|
* of the AmigaDOS, and a pointer to a struct MonDef
|
|
* which describes the screen-mode parameters.
|
|
*
|
|
* The routine returns 0 if it was unable to open the screen,
|
|
* or an unsigned char * to the display memory when it
|
|
* succeeded.
|
|
*
|
|
* The organisation of the display memory in text-mode is a
|
|
* little strange (Intel-typically...) :
|
|
*
|
|
* Byte 00 01 02 03 04 05 06 etc.
|
|
* Char0 Attr0 -- -- Char1 Attr1 -- etc.
|
|
*
|
|
* You may set a character and its associated attribute byte
|
|
* with a single word-access, or you may perform to byte writes
|
|
* for the char and attribute. Each 2. word has no meaning,
|
|
* and writes to theese locations are ignored.
|
|
*
|
|
* The attribute byte for each character has the following
|
|
* structure:
|
|
*
|
|
* Bit 7 6 5 4 3 2 1 0
|
|
* BLINK BACK2 BACK1 BACK0 FORE3 FORE2 FORE1 FORE0
|
|
*
|
|
* Were FORE is the foreground-color index (0-15) and
|
|
* BACK is the background color index (0-7). BLINK
|
|
* enables blinking for the associated character.
|
|
* The higher 8 colors in the standard palette are
|
|
* lighter than the lower 8, so you may see FORE3 as
|
|
* an intensity bit. If FORE == 1 or FORE == 9 and
|
|
* BACK == 0 the character is underlined. Since I don't
|
|
* think this looks good, it will probably change in a
|
|
* future release.
|
|
*
|
|
* There's no routine "SetChar" or "SetAttr" provided,
|
|
* because I think it's so trivial... a function call
|
|
* would be pure overhead. As an example, a routine
|
|
* to set the char code and attribute at position x,y:
|
|
* (assumed the value returned by RZ3Init was stored
|
|
* into "DispMem", the actual MonDef struct * is hold
|
|
* in "MDef")
|
|
*
|
|
* void SetChar(unsigned char chr, unsigned char attr,
|
|
* unsigned short x, unsigned short y) {
|
|
*
|
|
* unsigned struct MonDef * md = MDef;
|
|
* unsigned char * c = DispMem + x*4 + y*md->TX*4;
|
|
*
|
|
* *c++ = chr;
|
|
* *c = attr;
|
|
*
|
|
* }
|
|
*
|
|
* In gfx-mode, the memory organisation is rather simple,
|
|
* 1 byte per pixel in 256-color mode, one pixel after
|
|
* each other, line by line.
|
|
*
|
|
* When 16-bits per pixel are used, each two bytes represent
|
|
* one pixel. The meaning of the bits is the following:
|
|
*
|
|
* Bit 15 14 13 12 11 10 09 08 07 06 05 04 03 02 01 00
|
|
* Component g2 g1 g0 b4 b3 b2 b1 b0 r4 r3 r2 r1 r0 g5 g4 g3
|
|
*
|
|
* Please note that the memory layout in gfx-mode depends
|
|
* on the logical screen-size, panning does only affect
|
|
* the appearance of the physical screen.
|
|
*
|
|
* Currently, RZ3Init() disables the Retina Z3 VBLANK IRQ,
|
|
* but beware: When running the Retina WB-Emu under
|
|
* AmigaDOS, the VBLANK IRQ is ENABLED...
