- disabled by default (enable on a target-by-target basis) so it shouldn't
cause much breakage for non-rpc users
- some modifications to the binary chunk reader which should allow reading of
chunks encoded on various platforms (with certain limitations like lualong
can't read float lua bytecode, one must generate lualong bytecode from a float
lua)
- other misc changes.
- code cleanup
- the platform is now named 'sim'. You build it like this:
$ scons cpu=linux
The idea is to support more than one host OS by changing the "cpu" variable
above (for example cpu=osx, or cpu=win32). Also, a crude "host interface" was
defined in hostif.h. In theory, a host OS should only implement that interface
in order to run the eLua simulator. The implementation must reside in a file
called hostif_{os}.c (in this case hostif_linux.c). Too bad I don't have a MAC,
I would've loved to try this :)
REMEMBER: whem implementing a host interface, you CAN NOT rely on your regular
libc! You'll have to rewrite the syscalls (see host.c for an example on how to
do this in Linux).
- after you build it, don't start it directly, use the new "run_elua_sim.sh"
script to run it. It will set the terminal to raw mode, no echo, so it will
behave more like "traditional" eLua (even hangman.lua will run in this mode :) ).
Remember to run in on an ANSI capable terminal (although most of them support
ANSI emulation nowadays).
- you can exit from the simulator with "exit". You can't do this with CTRL+C if
you run it with "run_elua_sim.sh".
All in all, this looks pretty good and it's an excellent test platform. It will
do wonders when we integrate our own libc and we won't be able to figure out why
it doesn't work :)
- adc_wait_samples now returns the actual number of samples available at the
time it returns. this simplifies a pattern where one would wait on samples
if blocking and then subsequently check the number of available samples.
- adc.insertsamples(id, table, idx, count) function now available to take
samples and insert them into a table. this is slightly slower than
assignment for single values in a table, but can avoid having to use
getsamples (returning new tables) for certain situations
idx: starting index in table where values will be inserted
count: number of samples to get from channel id
of flash space.
NOTE: getsamples function is disabled since this is dependant on having a
buffer to get more than one sample.
Side note: single sampling without the buffer is faster by about 5-10
us/channel. It should be possible to sidestep the buffer in certain
situations for buffer enabled mode and get a similar benefit at the cost of
some additional complexity.
- ADC adjusted to work with sequenced acquisition setups. It should now
accomodate both sequenced and non-sequenced approaches on the backend.
A few more adjustments should be made to handle multiple sequencers
but right now neither LM3S or STM32 platforms use more than one sequencer.
- Added adcpoll.lua to demonstrate a simple approach for using clocked
acquisition and displaying results as they become available.
- ADC now works for STM32 (all 16 channels!). This should receive more
extensive testing, but everything should be working at this stage.
- the build system now pays attention to changes in header files meaning that
if any headers change or if the romfs changes (since it is generated as a
header) these changes will get recompiled without having to do a clean.
- Removed the QR code from the navigation frame :) I like it, but it just doesn't fit there.
- Some more (hopefully final) fixes for AT91SAM interrupt handlers.
Sorry, I commited a wrong test file.
wb_build.lua now supports the logo_onclick_link parameter, of wb_usr.lua
It defines an URL to be opened in a blank target windows.
Helpfull to bring navigation back to a "homepage".
- removed getsmoothing, setfreerunning, samplesready
- isdone has returned so that one can check if the reason why the buffer is
dry is because no more samples are being collected
- smoothing should support fairly large lengths now (as long as you have the
memory)
- added support to adc.sample to take a table as the first argument so that a
set of channels can be started at closer to the same time.
example:
adcchannels = {0,1,2,3}
adc.sample(adcchannels,8)
this should collect samples on all 4 channels starting nearly at the same
time.
- more comments added to elua_adc.c to describe behavior.
Misc
- remove rndpow2, not being used
