Now the CURRENT_DEFN field of the flags halfword in the pdbs_config
object is actually used, both when printing configuration objects and
when setting a current. It never takes any value other than 0 (_I) yet,
but this easily extends to power and resistance.
This commit adds the toggle_hv_preferred command, and makes printed
configuration objects show the state of the HV_Preferred flag. The
flag still isn't used by anything else yet though.
This commit changes back to the original plan of having one set_vrange
command that sets both the vmin and vmax at once, instead of separate
set_vmin and set_vmax commands. This will allow checking that the range
is valid every time it's set instead of having to wait until
configuration is written to flash.
Due to a typo, it would clear all bits except the HV_Preferred bit.
This commit fixes the bug, and refactors the clearing code to make typos
like this harder to make.
Firmware 1.2.0 will have more configuration flags than previous
versions. This commit adds macros for those flags. There's also a
field added to the flags halfword that says whether a current, power, or
resistance is configured, so this commit makes the clear_flags command
not modify that field.
They were already mostly in sections, but without headers. This commit
moves all the commands under new categories in the console_config.md
documentation file.
The new tempate variable sets the data role, power role, and
specification revision in one fell swoop. It's used by the PE and DPM
alike for creating messages, and in the future it may have a part in
determining if we're doing PD 2.0 or 3.0.
All the internal functions and definitions have been moved out of
lib/include/. Includes are made with the semantically correct brackets
("" or <>) throughout the firmware and library. That is to say, the
library is essentially done at this point, with only documentation
changes left to be made.
This commit splits the old messages.h file into two, one private
(messages.h) and one public (pdb_msg.h). This new arrangement keeps the
old model of one message pool for all the PD Buddy firmware library, but
moves the macro for the number of objects it contains into a new file,
pdb_conf.h, placed at the project root. The pool itself is kept in the
new pdb_msg.h file, since the DPM may need to access it.
The new configuration file also contains the stack sizes for the PD
Buddy threads (some will be moved back to secrecy in the future once the
needed sizes are known, but the PE's stack size should be kept in
pdb_conf.h since user code needs that stack).
To do this, a couple of the events had to have their definitions moved
to lib/include/pdb_pe.h. This isn't a problem in and of itself, but if
more internal-use events are added to policy_engine.h there could be
trouble. To mitigate this, I added a comment as a reminder to make sure
any new events don't overlap the public ones defined elsewhere.
Not the static globals yet, just the public ones. I suppose this change
isn't technically necessary since the PD Buddy Sink is a single-port
device, but I want its firmware to be a shining example of how to use
the library.
Now the user-visible FUSB302B functions all take a struct
pdb_fusb_config * as a parameter. The static functions don't use it
yet, but at least the public API of this code is in its finished state.
Apparently one of the threads was using too much stack space?? This
will require investigtion later, but for now increasing their stack
space fixed some weird problems I was having with this patch.
The code compiles again, and it seems to work as it did before. There's
still a lot to do (we still have a mess of globals), but the PE
correctly calls the new DPM functions via the list of callbacks in the
configuration object.
For now, the new <pdb.h> file only has a function to start the library,
based on the old start_pd function from main.c. It'll eventually be all
a user needs to include, but there's a lot more refactoring to do.
