Make struct am7xxx_header and related types private
There is not need for struct am7xxx_header, am7xxx_packet_type, and the
other headers structs to be in the public am7xxx.h file.
Antonio Ospite [Wed, 25 Jan 2012 14:26:44 +0000 (15:26 +0100)]
Implement am7xxx_get_device_info()
Add support for packet type 0x01, which can be used to query device
information like the native width and native height.
Introduce also read_data(), read_header(), unserialize_header()
which are needed by am7xxx_get_device_info()

picoproj: make the -f option mandatory
Passing an image file name is now mandatory, before that the user could
be induced into thinking that a command like the following was sending
an image:
./picoproj -W 800 -H 480 -F 1 some_image.jpg
while the actually intended command line was:
./picoproj -W 800 -H 480 -F 1 -f some_image.jpg
^^
Note the missing -f in the first command line.

Implement am7xxx_set_power_mode()
The AM7XXX_PACKET_TYPE_POWER expects the power mode to be specified in
the header_data section of the header like a value between 0 and 4, but
with one bit per field, each field being a little-endian 32 bit integer.

Dump the data only in DEBUG builds
Also use -Werror only in DEBUG builds, otherwise normal builds fail with:
src/am7xxx.c:42:13: error: ‘dump_header’ defined but not used [-Werror=unused-function]

Add a HACKING.asciidoc file
Give some info about how to make a debug build and mention the coding
style used in the project, so new contributors know how to behave.
Antonio Ospite [Tue, 24 Jan 2012 12:38:35 +0000 (13:38 +0100)]
Serialize struct am7xxx_header properly before sending it on the wire
That is in order to:
1. keep data in the structs always in the host native byte order, this
is more natural and less error prone as we might forget to use
htole32() when setting struct fields or le32toh() when accessing
them;
2. be more portable: this way the buffer sent to the wire is
independent of struct alignments or paddings introduced by
compilers or required by a particular architecture.
