The exti layer now allows drivers to register interrupt callbacks
during board initialization. All details of the driver using a
particular EXTI pin have been removed from the EXTI layer so it
can now be used on any board without board-specific modification.
This includes some nice refinements provided by Mike Smith during
initial review. His original commits have been squashed into this
one.
Board specific HW configuration is now collected in a single .c
file for each board. This HW configuration is #include'd into
the FW, BL and BU builds for each board.
These new .c files are found in:
flight/board_hw_defs/<board_name>/board_hw_defs.c
Parts of this information were previously duplicated between
the BL and FW builds. This commit cleans up the duplication.
Using a #include on a .c file is a bit ugly but it allows us
to ensure that all of the symbols in the board_hw_defs.c file
are *ONLY* used in the PIOS_Board_Init() function for each
software build.
If no telemetry link is configured, this will force the board
to reset before finishing init. The BootFault logic will
catch this after 3 resets and will boot with default hwsettings
on the next reset.
This won't currently ever fire on OP though since we always
configure the serial telemetry interface. This just makes sure
the pattern is present in case anyone decides to compile without
serial telemetry.
OpenPilot platform (and thus sim too) was missed when the
DIAG_TASKS macro was broken out from the DIAGNOSTICS macro.
This allowed accesses to the TaskInfo UAVO even though it hadn't
been initialized.
Some modules are written such that they can be included
or excluded at runtime. These are added to the OPTMODULES
list in the makefile for a given board.
This change provides a mechanism to allow a build to force
a given module to be built-in (ie. always initialized)
regardless of the configuration in hwsettings.
The main use case for this is to handle a module being optional
on one platform but essential on another.
All modules added to the MODULES list in the Makefile will
automatically result in a matching #define in the form
MODULE_TheModuleName_BUILTIN
being defined in the CFLAGS for all compiled source.
Note that the capitalization of TheModuleName must match
exactly the capitalization used in the MODULES list.
This allows each device to be moved (at compile time) to a
different adapter. This is the first step to allowing devices
to be attached to different i2c adapters.
The main purpose of this new COM implementation is that it is
much simpler, and requires less code space. This takes a bit
of the pressure off of the CC bootloader which was right at
the limit of available code space in the bootloader partition.
This is not intended to ever be used by the application.
This driver also formalizes the assumptions in the bootloader's
usage of the COM layer. All messages are assumed to arrive
in atomic chunks from the HID layer.
These files do not contain content from the ID in the header.
This name seems to have been cut/pasted all over throughout
the openpilot source tree and should be removed from any files
that should not rightfully be attributed to this person.
This can be used by the GCS firmware uploader widget to boot
the firmware with a (temporarily) defaulted hwsettings uavo
so that a user can easily recover from a bad/incompatible
hwsettings configuration without wiping all settings.
This uses the same mechanism that the BootFault auto-recovery
code already uses in the CC firmware. The auto-recovery is
triggered by setting the failed-boot counter to a maximum
value forcing recovery on the next FW init.
The PIOS_COM_ReceiveBufferUsed() function call is no longer
necessary since the same semantics can be achieved using calls
to PIOS_COM_ReceiveBuffer().
Summary of changes:
* USB CDC and HID drivers are completely split apart.
* This will allow different max buffer sizes for HID and CDC.
* USB descriptors have been overhauled:
* Proper structs/macros/enums declared for USB (see pios_usb_defs.h)
* Two common descriptor definitions. One for HID+CDC another for HID only.
See pios_usb_desc_{hid_cdc,hid_only}.c for details.
* Long standing bugs in OP USB descriptors became much more obvious with the
new struct definitions.
* Board specific USB initialization is now in pios_usb_board_data.h in each build target.
* Definition of USB descriptors is now entirely indpendent of STM32 libs.
Glue into STM32 libs is provided by pios_usbhook.c.
* Removed a lot of stale/irrelevant USB #defines throughout the tree.
* Improved naming consistency throughout USB code:
* PIOS_USB_HID_* now refers to the HID endpoint code.
* PIOS_USB_CDC_* now refers to the CDC endpoint code.
* PIOS_USB_* now refers to the low-level USB code.
* PIOS_USB_BOARD_* now refers to board-specific USB data
* PIOS_USBHOOK_* is glue between PIOS and STM32 USB libs.
* struct usb_* and enum usb_* and USB_* and HID_* are all types from the USB spec.
* Shrunk the buffer size on the CDC call mgmt endpoint to save some RAM.
* Made a few more USB related variables static to save some RAM.
