This is a partial rework of Cossacs' camera gimbal software.
This patch adds LPF to airframe attitude used for camera stabilisation
and feed forward for camera actuators. Either of options can be
disabled on the compilation level to save flash and RAM if not
required.
Original Cossacs' code was optimized and code flow shortcuts were
added where applicable.
This is a partial rework of Cossacs' camera gimbal software.
This patch adds LPF to some of manual control inputs. Mostly
useful are accessory channels (for camera gimbal control) and
yaw channel (for smooth filming). The code may be used for
stand-alone CC[3D]-based gimbal software, but also should work
for complete FC+camera system.
Serial ports now have a new HW setting called DebugConsole
which can be used to dump internal state to a serial port
for debug.
To enable this feature, you need to:
- make fw_coptercontrol_clean
- make fw_coptercontrol ENABLE_DEBUG_CONSOLE=YES
- configure one of the serial ports as DebugConsole in the GCS
- save settings
- power-cycle your board
Things to note:
- The console is at 57600,8N1.
- This is not currently configurable via the GCS.
- You can only have a single console enabled at a time.
These compiler options place each function and each global variable
into its own ELF section in each .o file. This, combined with the
linker option --gc-sections allows the linker to evict unused functions
and variables from the final ELF file.
On CC, the firmware flash bank is only 118784 bytes in total.
This commit reduces the .text segment from 114120 to 83536 and .data
from 572 bytes to 560 bytes. That frees up a grand total of 30596 bytes
of flash and 12 bytes of RAM.
Adds a new RCTransmitter setting for the USB HID interface which
emulates a USB HID joystick. The scaled RC receiver channels
from any RCVR protocol are passed through to the various emulated
joystick controls.
The main use for this feature is to allow you to use your own RC
transmitter with any RC simulator on a PC.
This is known to work with CRRCsim but should work with any simulator
that supports joystick input.
Use new PIOS_USB_UTIL_AsciiToUtf8() function to compose the
USB serial number rather than repeating that code for each
board.
All boards now append "+FW" or "+BL" to their USB serial numbers
to allow the descriptors to differ between FW and BL images.
Removes hard-coding of JTAG interface config in the
<board>_program make macros.
This allows the use of STLINKv2 for F4 boards while
continuing to use the FOSS JTAG revB on F1 boards.
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.
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.
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.
