----! DESCRIPTION !-------------------------------------------------------------
|
||
|
'-------------'
|
||
|
|
||
|
The Mackapar Suspended Particle Exciter Display, Rev 3 ("the device") is a 3D
|
||
|
vector display unit. Straight lines are drawn between consecutive vertices in a
|
||
|
constant loop, with customizable colors per vertex. The effect is similar to a
|
||
|
free floating 3D model.
|
||
|
The area of the projected model is about 1x1x1 meters, and projection occurs
|
||
|
1.5 meters above the device.
|
||
|
The emitters are capable to rotate around the Z axis at 50 degrees per second,
|
||
|
allowing for easy animation of projected models.
|
||
|
Up to 128 lines may be projected, but the more lines are projected, the more
|
||
|
severe the flickering gets.

||

----! INTERRUPT BEHAVIOR !------------------------------------------------------
|

'--------------------'
|
||
|
|
||
|
A, B, C, X, Y, Z, I, J below refer to the registers on the DCPU
|
||
|
|
||
|
A: Behavior:
|
||
|
|
||
|
0 Poll device. Sets B to the current state (see below) and C to the last error
|
||
|
since the last device poll.
|
||
|
|
||
|
1 Map region. Sets the memory map offset to X, and the total number of vertices
|
||
|
to render to Y. See below for the encoding information.
|
||
|
|
||
|
2 Rotate device. Sets the target rotation for the device to X%360 degrees.

|
----! VERTEX ENCODING !---------------------------------------------------------
|
||
|
'-----------------'
|
||
|
|
||
|
Each vertex occupies two words of information in the main DCPU RAM. The data is
|
||
|
encoded as (in LSB-0 format):
|
||
|
First word: YYYYYYYYXXXXXXXX
|
||
|
Second word: 00000ICCYYYYYYYY
|
||
|
Where XXXXXXXX is the X-coordinate of the vertex, YYYYYYYY is the Y-coordinate,
|
||
|
ZZZZZZZZ is the Z-coordinate, CC is color, and I is intensity.
|
||
|
Z is deeper into the screen, if the device is placed face up on the ground, this
|
||
|
translates to "up" relative to the user.
|
||
|
Possible color values are 0: black, 1: red, 2: green, 3: blue.
|
||
|
If the intensity bit is set, the color is drawn as more intense.
|
||
|
The black color is meant to barely be visible at all, except for in very dim
|
||
|
environments, or if the intensity bit is set.

|
'-------------'
|
||
|
|
||
|
0x0000 ERROR_NONE There's been no error since the last poll.
|
||
|
0xffff ERROR_BROKEN There's been some major software or hardware problem,
|
||
|
try turning off and turning on the device again.
