Rigol CSV to VCD converter
This (WIP) crate intends to transform the CSV output from a Rigol PLA2216 logic analyser probe to VCD format.
Quickstart
cargo run --release < data/test1.csvData 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

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).
