Hi, as already mentioned in my earlier mail we have implemented the API and protocol for having a driver for our own open hardware and open software device "hsa-tple".
Can you give help me how to use the session bus correctly as I haven't found further documentation. We use sigrok-cli with the time parameter: > $ sudo sigrok-cli -l 5 -O vcd -o outfile.txt -d > hsa-tple:conn=/dev/ttyACM0:serialcomm=9600/8n1 --time=10000 --probes='0-7' Or this way using samples counter (baudrate can furthermore be changed): > $ sudo sigrok-cli -l 5 -O vcd -o outfile.txt -d > hsa-tple:conn=/dev/ttyACM0:serialcomm=9600/8n1 --samples=10000 > --probes='0-7' Everything seems to work as excepted until we open and read the output file. We always get "0" as timestamp. How can this value be increased? What kind of meta data or usage is needed? > $date Fri Jan 10 16:54:02 2014 $end > $version libsigrok 0.2.2 $end > $timescale 1 ms $end > $scope module libsigrok $end > $var wire 1 ! 0 $end > $var wire 1 " 1 $end > $var wire 1 # 2 $end > $var wire 1 $ 3 $end > $var wire 1 % 4 $end > $var wire 1 & 5 $end > $var wire 1 ' 6 $end > $var wire 1 ( 7 $end > $upscope $end > $enddefinitions $end > $dumpvars > #0 > 1! > #0 > 1$ > #0 > 0! > #0 > 1! > #0 > 0! > #0 > 1! > #0 > 0! > #0 > ... We send a SR_DF_HEADER and a SR_DF_END packet. Inbetween there are a lot of SR_DF_LOGIC packets. Is the last one the problem? Are we only allowed to send one packet with all samples at once? At the moment we start a measurement, stop it, dump the samples. During the receiption of samples we already give them to the session bus. What are the SR_DF_FRAME_BEGIN and SR_DF_FRAME_END used for? Should they be used instead/ additionally? Finally another question: we only save samples when input levels have changed to save memory. This is a kind of internal VCD. Instead of creating a whole lot of samples between two sample timestamps that are the same (what is currently not implemented yet) -- is there a way around? Can this be ported to be RLE or something? Help is very appreciated! Thanks in advance. Bye, Matthias ------------------------------------------------------------------------------ CenturyLink Cloud: The Leader in Enterprise Cloud Services.
