373689207a Add a 1-tap IIR filter into the gyros in the feedback path. This will make the
stabilization output a bit more resilient to the high frequency noise from
gyros.  However this value shouldn't be too high as it will increase the phase
delay of the feedback loop and decrease stability.  Default is 5 ms.

Note: this resests the stabilizationsettings object.  Sorry guys.

d1104d3fdc alarms: lower heap warning and critical thresholds for CC
Free heap on CC is currently 160 bytes so the current thresholds
were causing a continual alarm condition, thus preventing arming.

fc1e3f574c OP-423: Split task create and module init in order to postpone task creation once the full heap is available.
Also implement some ordering (quite ugly still) in the module init and task creation order so we can decide which module to start/init first
and which module to start/init last.
This will be replaced/adapter with the uavobject list later (once it's implemented).
reserving some space for module init and task create parameters to customize module/task creation (this will be usefull once we get the list and customization from customer).

Changes have been made for OP and CC. Tested comped with CC,OP, sim_posix.
Only ran on bench with CC for couple of minutes (code increase expected but no dropping of stack which is good).

This gives task creation at the time wherethe all heap is available.

65cf467ca4 OP-423: move the module initialize funtion into a specific section for OP and CC.
- create linker section for those <module>Initialize()
- later this list will incorporate parameters as well. (this probably will be more a OP feature to swap/remove/delete module on the fly.
- this is not done at compile time anymore by Makefile.
- this will allow us to have control on the module start at run-time (not implemented but build the ground for it).
- this simplify the startup (Part of code re-org).
- this change does not affect sim_posix and win32 (since they don't need that)
- ensure it's compiling for PiOS.posix
- port to PiOS.win32 but not tested (not compiled)
- tested on CC
- compile on OP.
- this free ~200 bytes.
- current avalable bytes (is we keep the same remaining bytes on the stack than before) is easily passed the 1.2Ko mark on CC with new gcc (4.5.2)
- this does not include init-reorg for each module (I still think more can be freed)

aeda61d252 usart: serial telemetry can be disabled to free USART
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.

50e819192b usart: make CC USART ports compile-time configurable
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.

ab4e15e9aa OP-423 also claim (at run-time) the remaining un-used bytes (between heap and end of RAM) that are for data growth (needed at compile time).
CAREFULL: the heap section need to be the last section in RAM to avoid overwritting data...

Tested with GCC 4.5.2 this gives 1K of free bytes usable in heap right away (including the 200 bytes saved just by using the new gcc).
This does not include any code re-org yet!

3780de8d3e OP-423 port to OP (heap2) the previous changes done in CC (heap1) (see c95b1991665944bed634d9cfe7fccb21dbedb167)
I managed to test CC with heap2 changes and the init stack claimed back to heap once scheduler starts.

the changes of this commit are OP related (just cleanup on CC side):
Arch specific stuff (in reset vector) to hide this from portable code:
     - switch back to MSP stack before starting the scheduler so that the sheduler can use the IRQ stack (when/if needed).
     - call the C portable function in heap2 to claim some stack back (the number to claim is taken from linker file).
     - start the scheduler from reset vector (I move this here from main because it make sense to not go back to C (so that I don't need to copy the rolled stack in case the sheduler returns). This make it more clean.
     - Also I have added the call to the mem manager if sheduler return. that way, we don't reset indefinitely if memory runs out. We will go to this handler and figure things out (right now, it's just looping but at least not rebooting. Probably trap NMI would be better (later improvement).

c95b199166 OP-423 do the arch specific stuff (in reset vector) to hide this from portable code:
- switch back to MSP stack before starting the scheduler so that the sheduler can use the IRQ stack (when/if needed).
 - call the C portable function in heap1 to claim some stack back (the number to claim is taken from linker file).
 - start the scheduler from reset vector (I move this here from main because it make sense to not go back to C (so that I don't need to copy the rolled stack in case the sheduler returns). This make it more clean.

The part missing for this part is the weak attribute for the function in heap1.c so that we don't have to update everything with empty stub.
I think the weak atrribute for C function called in assembly is arch dependent so I am not sure if this is possible (will look into it, maybe somebody outthere nows).
Right now, it's heap1 dependent and won't work with heap2. I will clean that up the next couple of days.

I did some test and it looks good.
this is without init code re-organization so we don't free as much as we will be it's good starts.

This compile with sim_posix (since it does not affect portable code) so this is really clean.
I only tested this with CC. I will port it for OP when I will work on heap2.

404c026188 Patch from Zippe to use cycle timer for CPU monitoring. 2011-06-13 00:24:30 -05:00
Mathieu Rondonneau
7598e898fa OP-423 Step-1: split system stack and implement water mark for IRQstack:
- use IRQStack for ISRs (at begening of SRAM) (let's call it the irq stack)
- use end of heap for stack needed during initialization (let's call it the init stack).
- the systemStats in GCS indicate the remaining bytes in the IRQ stack (this is realy usefull to monitor our (nested) IRQs.

This is the base ground to provide as much memory as possible available at task creation time.

Next step is to re-organize the initialization in order to move all the init out of the thread's stacks onto the init stack.
This will provide as much memory as possible available at task creation time.
Basically the stack during initialization will be destroyed once the scheduler starts and dynamic alloc are made (since the init stack is at the end of the heap). We will need to make sure we don't clobber the heap during initialization otherwise this will lead to stack corruption.
