This should mark an end to the compile-time selection of HW
configurations.
Minor changes in board initialization for all platforms:
- Most config structs are marked static to prevent badly written
drivers from directly referring to config data.
- Adapt to changes in .irq fields in config data.
- Adapt to changes in USART IRQ handling.
Major changes in board initialization for CC:
- Use HwSettings UAVObj to decide which drivers to attach to
the "main" port and the flexi port, and select the appropriate
device configuration data.
- HwSettings allows choosing between Disabled, Telemetry, SBUS,
Spektrum,GPS, and I2C for each of the two ports.
- Use ManualControlSettings.InputMode to init/configure the
appropriate receiver module, and register its available rx channels
with the PIOS_RCVR layer. Can choose between PWM, Spektrum and PPM
at board init time. PPM driver is broken, and SBUS will work once
it is added to this UAVObj as an option.
- CC build now includes code for SBUS, Spektrum and PWM receivers in
every firmware image.
PIOS_USART driver:
- Now handles its own low-level IRQs internally
- If NULL upper-level IRQ handler is bound in at board init time
then rx/tx is satisfied by internal PIOS_USART buffered IO routines
which are (typically) attached to the COM layer.
- If an alternate upper-level IRQ handler is bound in at board init
then that handler is called and expected to clear down the USART
IRQ sources. This is used by Spektrum and SBUS drivers.
PIOS_SBUS and PIOS_SPEKTRUM drivers:
- Improved data/API hiding
- No longer assume they know where their config data is stored which
allows for boot-time alternate configurations for the driver.
- Now registers an upper-level IRQ handlerwith the USART layer to
decouple the driver from which USART it is actually attached to.
All receivers now fall under the same driver API provided
by pios_rcvr.c.
This is part of a larger sequence of commits that will
switch the receiver selection over to boot time dynamic
configuration via UAVObjects.
It was tested being merged with OP-472_CorvusCorax_CopterControl-Guidance_v3
branch, Spektrum on USART3 and GPS on USART1 and seems to work.
Currently defaults mimic original behavior, that is, if USE_SPEKTRUM
is not defined - define USE_PWM and USE_GPS. Thsi should be refactored
later to make it configurable from the Makefile.
Also it was not ported to the OP MB: it currently does not support the
S.Bus hardware and still has original behavior with the patch. But this
is one more step to dynamic configuration of ports.
TODO: This should be dynamic in the future.
But for now define any compatile combination of:
USE_I2C (shared with USART3)
USE_TELEMETRY
USE_GPS
USE_SPEKTRUM
USE_SBUS (USART1 only, it needs an invertor)
and optionally define PIOS_PORT_* to USART port numbers
Defaults are:
#define PIOS_PORT_TELEMETRY 1
#define PIOS_PORT_GPS 3
#define PIOS_PORT_SPEKTRUM 3
#define PIOS_PORT_SBUS 1
#define USE_TELEMETRY
#define USE_GPS
Telemetry, GPS and PWM input are enabled by default.
When running flight software from master (cf74908), my
config was pushing the system module stack usage to within
16 bytes of its limit. This triggers a stack overflow
alarm which prevents the quad from arming/flying.
This change increases the available stack size such
that there are 72 bytes of stack free (a previously stated
safe margin) when my quad is sitting idle and unarmed on
the bench.
also increase the telem queue to decrease event errors (can be reverted later if
we need the memory back)
