U?? is called FDR internally in some documentations. Barudan stitch information. Usually these are .u01 files.
- .U01 contains command, stitch triplet data.
- .U01 contains commands for SLOW, FAST (in both stitched and unstitched forms)
Each file consists of two parts: a header, and a body.
Header
The header comes in two parts.
Part A
- Bunch of 0x30 "0" characters for 128 characters in all for an unknown reason.
Part B
Some basic extends information
| Type | Bytes | Value | Description |
|---|---|---|---|
| `s16` | 2 | -X | Left |
| `s16` | 2 | -Y | - Bottom (in y-flipped) |
| `s16` | 2 | +X | Right |
| `s16` | 2 | +Y | - Top (in y-flipped) |
| `u32` | 2 | 0 | Unknown only seen (0) |
| `u32` | 2 | count_commands | Stitch Data Count, (if multiplied by 3 will give the length of body) |
| `u16` | 2 | x_final | Final X position |
| `u16` | 2 | y_final | Final Y position (-Y if we're y-flipped) |
The remainder of the 128 byte section is padded with 0x00 data.
Body
The body starts at position 0x100 (256)
The body consists of encoded stitches. The stitches are in:
Control, X, Y form.
| BYTE | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
|---|---|---|---|---|---|---|---|---|
| 1 | 1 | -x | -y | c | c | c | c | c |
| 2 | y | y | y | y | y | y | y | y |
| 3 | x | x | x | x | x | x | x | x |
The control byte contains an always set value, followed by 2 bits of directional information for the X, Y values (whether they are + or -), then five bytes of control.
