+The tool flexipix_config_gen creates the major part of a flexipix config file |
|
2 |
+from a drawing of the display in DXF format. |
|
3 |
+ |
|
4 |
+See for example "examples/5x2panels8x12.dxf". |
|
5 |
+ |
|
6 |
+The layers containing drawing data are: |
|
7 |
+ |
|
8 |
+layer "video": one rectangle describing the area of the video frame, |
|
9 |
+ representing the outline of the video area of the physical |
|
10 |
+ display |
|
11 |
+layer "pixel": one circle (diameter does not matter) for each LED |
|
12 |
+ located at the correct position, representing the |
|
13 |
+ physical position of the LED in the physical display |
|
14 |
+comment: the two points above mean that the drawing is actually a to-scale |
|
15 |
+ mechanical drawing of the real display |
|
16 |
+layer "cable 1": lines connecting the pixel circles in the drawing in the |
|
17 |
+ same way as the real wires connect the real LEDs, |
|
18 |
+ the lines have to go a bit into each pixel circle, |
|
19 |
+ make sure different cable lines do no touch or cross |
|
20 |
+layer "cable 0": another layer for data cables, use this when a cable line |
|
21 |
+ crosses a cable line on layer "cable 1" |
|
22 |
+layer "distributor 000": one rectangle describing the first distributor, all |
|
23 |
+ cable line to the first pixel of each chain must |
|
24 |
+ start in this rectable; the cable lines going out |
|
25 |
+ of this rectangle must be in order, i.e. first |
|
26 |
+ line leaving is output 0, second one is output 1, |
|
27 |
+ and so on; the first four outputs go to the first |
|
28 |
+ RJ45 connector, ...; the text in the drawing is |
|
29 |
+ ignored (example file contains "000" for the |
|
30 |
+ human that is seeing the drawing) |
|
31 |
+layer "distributor 001": second distributor (not in example drawing) |
|
32 |
+layer "distributor 002": ... |
|
33 |
+layer "network": a small line going into the distributor rectangle, |
|
34 |
+ counting outputs starts at this line, no other purpose |
|
35 |
+ besides marking the position of the first output |
|
36 |
+ |
|
37 |
+There are four more layers for providing some numbers about the installation. |
|
38 |
+Those numbers are encoded in the layer names. There are no drawing objects |
|
39 |
+on those layers. |
|
40 |
+ |
|
41 |
+layer "cfg_width 40": number of pixels in the video frame in horizontal |
|
42 |
+ direction |
|
43 |
+layer "cfg_height 24": number of pixels in the video frame in vertical |
|
44 |
+ direction |
|
45 |
+layer "cfg_outputs 32": number of outputs at each distributor |
|
46 |
+layer "cfg_pixels 96": number of pixels connected to each output of the distributors, |
|
47 |
+ if outputs have different numbers of pixels, |
|
48 |
+ use the maximum number |
|
