Move the include flags for files in the source tree from
configure.ac to Makefile.am where they belong. Also use
AM_CPPFLAGS instead of CFLAGS/CXXFLAGS to make sure the
files in the build/source tree are always picked up first.
Also, remove the include/libsigrok sub-directory from the
search path, thereby making the <libsigrok/> prefix mandatory
when building libsigrok itself. This matches the convention
already imposed on users of the library.
Tested on an MSO1104Z with firmware 00.04.02.SP4.
The analog channels are captured correctly. For the MSO series, with digital
channels, there are two outstanding issues:
1. Logic data is retrieved per-channel, one byte per sample, with the value
in the LSB of each byte. The current datafeed logic format doesn't allow
this format to be passed on directly. I suggest we resolve that rather than
making the driver buffer and interleave the data.
As stands, the code will retrieve data for all channels and pass it onto
the datafeed with unitsize=1. Channel D0 can used correctly if selected
alone. For other channels, data is passed to the frontend but the API does
not provide a way to associate it with the correct channel.
2. Channels CH3 and CH4 are multiplexed with D0-7 and D8-15 respectively, so
enabling these is mutually exclusive. We don't currently have a way to
express this constraint to the frontend.
