Hi all, I made a short stereo chirp in Audacity, exported it as stereo .wav. Imported this into PulseView, which imported fine, and saved this as stereo.sr.
Then I tried opening stereo.sr in PulseView, and I exported it as a stereo.vcd file - the stereo.vcd file seems to be saved fine. Note that this .vcd file has a line like `$scope module libsigrok $end` or similar, which will cause sigrok to print this, if you try loading that .vcd file:
sr: input/vcd: Skipping scope with application's package name: libsigrok
... so, I had to change that line to `$scope module top $end`. However, if I then start a new PulseView session (PulseView 0.5.0-git-9d307c6, libsigrok 0.6.0-git-d7df9dc/4:0:0 (rt: 0.6.0-git-d7df9dc/4:0:0) on Windows 10), and I try importing this stereo.vcd, then PulseView just shuts down, without any error messages. I have stored the stereo.sr and stereo.vcd files in this gist: https://gist.github.com/sdbbs/1b7b4e91cae563f1f5de565d05d11515 I also tried opening the .vcd in sigrok-cli with the intent of exporting .sr from there - log messages indicate that the .vcd file is parsed by sigrok-cli, however the output .sr file is never created. Since these are analog signals, I was suspecting that sigrok does not support analog data in .vcd - but the wiki seems to imply that it is supported: https://sigrok.org/wiki/File_format:Vcd
Signals of the VCD "real" type map to analog sigrok channels. Precision handling currently is WIP.
So, can anyone explain what am I missing, in regards to importing a .vcd file with analog data in sigrok/PulseView? Here's the log of running sigrok-cli on the .vcd file: ``` $ "C:\Program Files (x86)\sigrok\sigrok-cli\sigrok-cli.exe" -l 5 -i stereo.vcd -o stereoB.sr sr: [00:00.000000] log: libsigrok loglevel set to 5. sr: [00:00.000000] backend: libsigrok 0.6.0-git-d7df9dc/4:0:0. sr: [00:00.000000] backend: Libs: glib 2.44.1 (rt: 2.44.1/4401:1), libzip 1.5.2, libserialport 0.1.1/1:0:1 (rt: 0.1.1/1:0:1), libusb-1.0 1.0.20.11003-rc3 API 0x01000104, hidapi 0.8.0-rc1, libftdi 1.4. sr: [00:00.000000] backend: Host: x86_64-w64-mingw32.static.posix, little-endian. sr: [00:00.000000] backend: SCPI backends: TCP, serial, USBTMC. sr: [00:00.000000] backend: Firmware search paths: sr: [00:00.019000] backend: - C:\Users\user\AppData\Local\sigrok-firmware sr: [00:00.019000] backend: - C:\ProgramData\sigrok-firmware sr: [00:00.019000] backend: - C:\Users\Public\Documents\sigrok-firmware sr: [00:00.019000] backend: - C:\Program Files (x86)\sigrok\sigrok-cli\share\sigrok-firmware sr: [00:00.019000] backend: - C:\Program Files (x86)\sigrok\sigrok-cli\share\sigrok-firmware sr: [00:00.019000] backend: Sanity-checking all drivers. sr: [00:00.019000] backend: Sanity-checking all input modules. sr: [00:00.019000] backend: Sanity-checking all output modules. sr: [00:00.019000] backend: Sanity-checking all transform modules. srd: libsigrokdecode loglevel set to 5. sr: [00:00.024000] input: Trying module chronovu-la8. sr: [00:00.024000] input: Trying module csv. sr: [00:00.024000] input: Trying module trace32_ad. sr: [00:00.024000] input: Trying module vcd. sr: [00:00.026000] input: Module vcd matched, confidence 1. sr: [00:00.026000] input: Trying module wav. sr: [00:00.026000] input: Trying module logicport. sr: [00:00.026000] input: Trying module saleae. sr: [00:00.030000] input: Sending 2363921 bytes to vcd module. sr: [00:00.031000] input/vcd: Section 'date', contents 'Thu Oct 22 18:10:51 2020'. sr: [00:00.032000] input/vcd: Section 'version', contents 'libsigrok 0.6.0-git-d7df9dc'. sr: [00:00.032000] input/vcd: Section 'comment', contents 'Acquisition with 2/2 channels at 44.1 kHz'. sr: [00:00.033000] input/vcd: Section 'timescale', contents '100 ns'. sr: [00:00.033000] input/vcd: Samplerate: 10000000 sr: [00:00.034000] input/vcd: Section 'scope', contents 'module top'. sr: [00:00.034000] input/vcd: $scope, got: "module top" sr: [00:00.034000] input/vcd: $scope, prefix now: "top." sr: [00:00.034000] input/vcd: Section 'var', contents 'real 64 !
