Andrew Tridgell b0713ba412 AP_Param: support up to 16 character parameter names 
MAVLink allows for 16 chars, with no null termination if all 16 are
used
 2012-11-20 21:35:22 +11:00
Andrew Tridgell 736cb4c34b AP_Var: move the MetaClass lib into AP_Var 
AP_Var is the only one that uses it, and it generates warnings in our
build if we leave it in AP_Common
 2012-11-06 21:42:54 +11:00
Andrew Tridgell ef919c4e36 AP_Param: fixed a bug with setting nested parameters 
This bug meant that setting a parameter in a parent class for a doubly
nested parameter group, where the parameter index in the parent class
is 4 or greater would actually set the first element in that parent
class.

At the moment only one parameter fits these narrow constraints - the
RCn_DZ element of the RC_Channel_aux class. So if someone set RC5_DZ
to 17 in ArduPlane it would actually set RC5_MIN to 17.

Andrew Tridgell e6e25525bc AP_Param: avoid saving values within 0.01% of the default value 
this saves some more space due to rounding errors
 2012-08-08 13:13:30 +10:00
Andrew Tridgell c298d5130f AP_Param: major update to use default values in var_info table 
this stores the default value for all scalar variables in the var_info
table, which makes it possible to avoid storing default values in
eeprom. That allows us to oversubscribe the eeprom space with a much
lower risk of overrun.
 2012-08-08 12:11:57 +10:00
Andrew Tridgell e1725e9ea5 AP_Param: added some docs on the eeprom header format 2012-07-10 14:03:49 +10:00

Andrew Tridgell 4f90e6e844 build: cope with Arduino 1.0 in command line build 
this should autodetect 1.0 versus older builds

Amilcar Lucas 6e9ffb4249 correct small typos in comments 2012-03-11 21:30:09 +01:00
Andrew Tridgell f4329d2680 AP_Param: ensure we can't have duplicate keys in Parameters.h 
this is O(n^2), but only at startup, and takes less than 1ms to run.
It catches a very nasty coding error
 2012-03-02 15:48:28 +11:00
Pat Hickey 337af0c7a2 AP_Param: nested group recursion into next_group disableable by macro 
* c.f. 0251932c81fe7eb, e5515bb6ef82
 2012-02-29 19:48:43 -08:00
Pat Hickey 2648694489 AP_Param: One more nexted group recursion disableable by macro

 2012-02-29 18:48:54 -08:00
Pat Hickey eac8b66385 AP_Param: Make nested group recursion disableable by macro 
* Eliminates recursive calls inside AP_Param.
  This is important to Pat @ Galois, but not the project in general.
  Recursion depth on these functions is bounded structurally using
  existing nested group constructors (can't create loops in finite space)
  and checked at init time

Andrew Tridgell cb52b6c6d9 AP_Param: show numerical value in eeprom dump utility 2012-02-28 09:43:49 +11:00
Andrew Tridgell a432232db9 AP_Param: fixed v.load() on a sub-element of a AP_Vector3f 
this isn't actually used at the moment in APM, but we should get it
right in case someone does try to load a single element of a vector
 2012-02-28 09:43:49 +11:00
Andrew Tridgell 87a6d97f7b AP_Param: fixed setting of CAM_P_G in ArduCopter 
the variable CAM_P_G has the same prefix as the CAM_P group. We want
to allow for parameters having a common prefix with a group, so we
need to keep searching after we've found a group that matches the
prefix
 2012-02-27 10:54:33 +11:00
Andrew Tridgell fa443bd928 AP_Param: make the templating code a bit clearer 
add comments on the arguments, and name them in a clearer way
 2012-02-27 10:54:33 +11:00
Andrew Tridgell f10097a6d5 AP_Param: added some comments on AP_Vector3f handling 2012-02-25 11:37:20 +11:00
Andrew Tridgell 2e9105c68a AP_Param: added special handling for Vector3f 
We would like to be able to use Vector3f as a parameter while exposing
the individual elements of the vector as MAVLink parameters. This
change to AP_Param makes that possible, by giving AP_Vector3f a dual
personality
 2012-02-25 11:37:20 +11:00
Andrew Tridgell 53b87229ff AP_Param: added ParamToken type for variable list traversal 2012-02-19 17:05:28 +11:00
Andrew Tridgell 882cd4ea83 AP_Param: moved AP_Vector3f and AP_Matrix3f declarations to AP_Math.h 
this avoids us needing AP_Math.h in every utility sketch and example
 2012-02-18 10:51:57 +11:00
Andrew Tridgell 4b15b63d21 AP_Param: fixed copy-assignment operators for AP_Param vectors 2012-02-18 10:51:57 +11:00
Andrew Tridgell 7f3858cb7f AP_Param: added a set_and_save_ifchanged() method 
this can be used to avoid the scan() in more frequenctly saved
variables, such as the MAVLink stream rates in APM
 2012-02-18 10:51:57 +11:00
Andrew Tridgell 80a6773b8b AP_Param: added an initialised() method

Andrew Tridgell 601a991a46 added SITL_debug() macro 
this can be used to print a message into the logs in the SITL
simulator. This will be used for critical conditions.
 2012-02-15 08:50:45 +11:00
Andrew Tridgell be5ffdedbb AP_Param: allow dumping of AP_Vector3f 
this means the 'show' command in the CLI shows the compass offsets now
 2012-02-14 08:34:50 +11:00
Andrew Tridgell 74bbc72b11 move AP_Var code and example into libraries/AP_Var 
you can use AP_Var by defining USE_AP_VAR
 2012-02-13 16:22:53 +11:00
Andrew Tridgell d55a0c3a71 added AP_Param::show_all() 
this moves the logic into common code
 2012-02-13 16:22:52 +11:00
Andrew Tridgell 9175ebe33a change back to 256 max variables in _var_info[] 
this keeps the header to 24 bits, and allows the token to be 16
bits. If we need more variables we can put them in a nested group.
 2012-02-13 16:22:52 +11:00
Andrew Tridgell f2a6a31645 AP_Param: added group idx, and change packing of header elements 
adding a idx element to the GroupInfo will make it less likely that a
developer will change the IDs of group elements, and make it easier to
see that these IDs are important for identifying a variable in EEPROM

The header packing has changed to make it 24 bits on all platforms,
which allows us to lower the EEPROM variable max size to 1024 bytes
again
 2012-02-13 16:22:52 +11:00
Andrew Tridgell 678a1df3be fixed support for AP_PARAM_SPARE

Andrew Tridgell 92e0e929a4 AP_Common: replace strlcat_P() with a C implementation 
the one in the Arduino libc was giving us bogus results on one
machine, and is suspect. We couldn't spot what is wrong in the
assembler, but replacing the implementation with a C one fixes the
bug, so we replaced it

Andrew Tridgell 7098e8cfa1 first rough build for desktop CPUs 
this allows ArduPlane to build and startup on 'desktop' systems (eg. a
Linux box). Very rough for now, and only for HIL so far

Andrew Tridgell bcc2aed8fb initialise spare bits in AP_Var headers 
if we ever need these bits, it would be nice to know that they are
zero in existing eeproms

James Goppert 9c766d6373 Added override for mega upload protocol. 2011-09-26 20:29:09 -04:00
James Goppert 6abb8a0796 Modified Arduino.mk to use correct upload protocol if not overrided. 
The previous comment of upload protocol not working cannot be verified on
linux. If this problem persists on cygwin, please override with
UPLOAD_PROTOCOL=arduino in the enivornment before calling Arduino.mk

Mike Smith 42abbb41fd Add options to generate assembly listings for all of the compiled 
files.  This is a possible starting point for a tool to analyse the
call graph and stack usage of APM.

It's also interesting by itself.

tridge60@gmail.com dab8c0cca8 AP_Var: added EEPROM wear levelling 
This adds a variable length dummy variable at the front of the EEPROM
when we erase it, which has the effect of moving the location of any
hot variables within the EEPROM. This should improve EEPROM
life. Thanks to Mike for the implementation.

tridge60@gmail.com 06c4f60490 AP_Var: avoid wearing out EEPROM by re-writing the same value 
when saving a variable, this avoids EEPROM wear by checking if the
existing value is already the same as the value being written, and
avoiding the write.

Thanks to Mike Smith for the implementation
