# Rigol CSV to VCD converter
This (WIP) crate intends to transform the CSV output from a [Rigol PLA2216 logic analyser probe][PLA2216] to [VCD format][VCD].
## Quickstart
```shell
cargo run --release < data/test1.csv
```
## Data inputs/outputs
From Rigol support:
> The instrument is combining LA channels D0-D7 together, so that channel 0 is bit 0 and channel 7 is bit 7, this would be the same for LA channels D8-D15.
So the goal is to convert this string data:
```
Time(s),D7-D0,D15-D8,t0 = -0.01s, tInc = 1e-09,
-9.999999E-03,0.000000E+00,0.000000E+00,,
-9.999998E-03,0.000000E+00,0.000000E+00,,
(...)
```
To vectors on the VCD output (not necessarily equivalent to the above CSV, just illustrative):
```
$timescale 1 ns $end
$scope module top $end
$var wire 16 # data $end
$upscope $end
$enddefinitions $end
$dumpvars
b0000000000000000 #
$end
#9999995
b0000000000000001 #
#9999996
b0000000000000010 #
#9999997
b0000000000000011 #
#9999998
b0000000000000000 #
#9999999
```
## Current status
How it started (Rigol oscilloscope screenshot):
Hot it's going (VCDs converted from CSV at different timescales):
As one can see, there's still some bugs to iron out (or report upstream).
