[sigrok-devel] Fluke189 support

[Fabio <si...@ma...>]

Hello,

I'm trying to read the data from my Fluke189 with sigrok-cli. The Fluke189 is listed as supported, however it seems like its identifier is missing in the fluke-dmm code (for libsigrok-0.2.1-557-g8c9d4d6). I've made the necessary changes locally and I believe this is a bug (see attached patch).

The Fluke is now properly detected:
$sigrok-cli -d fluke-dmm:conn=/dev/cu.usbserial-A3000LQv --show
fluke-dmm - Fluke 189 V2.02 with 1 probe: P1

However I'm not sure how to read the data. How do I read a single sample ? This is what I tried:
$sigrok-cli -d fluke-dmm:conn=/dev/cu.usbserial-A3000LQv:serialcomm=9600/8n1 --samples 1 --continuous -l 4
sr: libsigrok loglevel set to 4.
srd: libsigrokdecode loglevel set to 4.
sr: serial: Received 1: '0'.
sr: serial: Received 27: 'FLUKE 189, V2.02,0093120208'.
sr: fluke-dmm: Setting sample limit to 1.
sr: session: Starting.
sr: std: fluke-dmm: Starting acquisition.
sr: std: fluke-dmm: Sending SR_DF_HEADER packet.
sr: session: bus: Received SR_DF_HEADER packet.
cli: Received SR_DF_HEADER
Press any key to stop acquisition.
sr: session: Running.
sr: session: Stopping.
sr: std: fluke-dmm: Stopping acquisition.
sr: std: fluke-dmm: Sending SR_DF_END packet.
sr: session: bus: Received SR_DF_END packet.
cli: Received SR_DF_END
Device only sent 0 samples.
Device stopped after 0 samples.


Thank you for your attention,
Fabio
