It's all right with me if people use my implementation of USB Power
Delivery in anything. This will make writing firmware for the PD Buddy
Dev a lot more reasonable, once it exists.
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).
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.
/!\ BROKEN BUILD /!\
This commit moves the library code to the library directory. This
causes the firmware to not compile. A few changes were made to reduce
the nubmer of errors, but some errors just aren't going to go away until
I go ahead with the planned changes.
There are still a few things that the standard says we Shall do and we
don't, but it Works For Me™. I haven't implemented anything with
regards to GiveBack support, but that doesn't matter just yet. Our
handling of VDMs isn't quite right either. Anyway, it successfully
negotiates with so-called Split PDO power supplies, which is more than I
can say about some commercial products.
