COMPLETE SAMPLE COPPER LIST
The following example shows a complete Copper list. This list is for two bitplanes-one at
$21000 and one at $25000. At the top of the screen, the color registers are loaded with
the following values:
REGISTER COLOR
COLOR00 white
COLOR01 red
COLOR02 green
COLOR03 blue
At line 150 on the screen, the color registers are reloaded:
REGISTER COLOR
COLOR00 black
COLOR01 yellow
COLOR02 cyan
COLOR03 magenta
The complete Copper list follows.
;
; Notes:
; 1. Copper lists must be in CHIP ram.
; 2. Bitplane addresses used in the example are arbitrary.
; 3. Destination register addresses in copper move instructions
; are offsets from the base address of the custom chips.
; 4. As always, hardware manual examples assume that your
; application has taken full control of the hardware,
; and is not conflicting with operating system use of
; the same hardware.
; 5. Many of the examples just pick memory addresses to
; be used. Normally you would need to allocate the
; required type of memory from the system with AllocMem()
; 6. As stated earlier, the code examples are mainly to help
; clarify the way the hardware works.
; 7. The following INCLUDEs are required by all example code
; in this chapter.
;
INCLUDE "exec/types.i"
INCLUDE "hardware/custom.i"
INCLUDE "hardware/dmabits.i"
INCLUDE "hardware/hw_examples.i"
