------------------------
This adds the functions of mathlib that make sense when numbers are integers:
functions [abs,max,min,random,randomseed,sqrt] and constant "huge"
so that idioms like this (from p.195 of Programming in Lua) also work:
for i = 1,math.huge do
...
if ... then break end
...
end
The square root gives the integer square root of positive numbers
(which would be floor(sqrt(f)) in a floating point world).
- add basic (no clock support) ADC implementation for AVR32, works on EVK1100
- add avr32-unknown-none-gcc to new lua-based build system to support crosstools-ng avr32 toolchain
The files that will be compiled to link an eLua image are now found automatically,
there's no need to specify them explicitly anymore. This applies only to the main
'build_elua.lua' build file, each target's 'conf.lua' still needs to specify them
explicitly (but can use the same automatic source file finding as the main build file).
Added a 'summary' display mode in the builder which displays less information
(thus making the output more readable) and also adds colors :) Not exactly
very useful but I saw this recently in cmake and I _had_ to implement it :)
Activate with "disp_mode=summary" in the command line.
Now a target can be reffered to also by its name, not only by the
corresponding _target object. Also added 'utils.lua' as a separate
file in utils/ (it used to be a part of build.lua)
- RTS/CTS pins may not have been configured in correct modes
- ensure that remapping for CAN peripheral occurs during startup so USART1's RTS pin is usable
$ lua build_elua.lua board=et-stm32 burn /dev/ttyUSB0
will invoke stm32ld (the default for stm32's platform 'burn' target) on port /dev/ttyUSB0.
I really have to document all this stuff somewhere. Don't panic though, for now you can use the old build system exactly like you used it before :)
- added support for per-backend targets. avr32 now has a 'burn' target (besides the regular 'prog') that can be used to build the image and burn it to the board (lua build_elua.lua board=atevk1100 burn). It is created in 'conf.lua'
- other fixes and improvements to the build system
well), per-project build directories and other nice stuff. So far used only for mux and rfs_server; 'lua mux.lua' or 'lua rfs_server.lua' to test (add "-c" to clean). Only needs lfs.
