Subject: input/protocoldata: reduce inter-frame gap for I2C waveforms
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=f6d0f7a83c5b5e31c1bffc9abaebb91822378f9e;p=libsigrok.git

input/protocoldata: reduce inter-frame gap for I2C waveforms

Space I2C data bytes the same as address bytes are spaced. Results in a
graphical presentation that is easier to inspect, and is less wasteful
at the same time (more data is seen at the same zoom level).
