ANSI terminal support (yet) and "recv" doesn't work anymore because XMODEM doesn't work over TCP/IP. Only for LM3S8962/LM3S6965 for now, but it should straightforward (not easy though)
to port it to other platforms. Only static IP for now. More TCP/IP functions need to be implemented (and an eLua module must be written to access them). To enable console over TCP:
- enable "BUILD_CON_TCP" in build.h, also disable "BUILD_XMODEM" and "BUILD_TERM" in build.h (you'll get an error if you don't)
- disable "BUILD_CON_GENERIC" in build.h (you'll get an error if you don't)
- edit your network settings in build.h
- build the image&burn it
- telnet to the address configured in build.h. Be sure to use a decent telnet client, like the one in Linux or putty. Don't try with telnet from Windows, as it surely won't work. Also, it might
not work with the telnet client from Tera Term Pro (didn't test this).
- type 'exit' from shell to terminate the connection.
Also, note that from this point on you'll need a newer version of binutils to compile for Cortex. I'm using binutils-2.19.50.tar.bz2 (from the snapshots page). 2.18 might work too, but I didn't
test it.
mathlib (sin, cos, tan and all the other functions from there).
- corrected "pwmled.lua" (removed a debug print)
- bumped version number to minor versn 0.4.1
I/O setup.
- the pd() module has a new method (board) and gets it CPU, platform and board name directly from the build system (command line macros). It's much easier to work like this.
- the samples (examples/) were updated to check pd.board() rather than pd.platform()/pd.cpu(), which is a much more logical way to do things, since it ties the sample to a
specific I/O configuration, not with a CPU.
- updated PWM code for AT91SAM7X, now the "piano" example works for both LM3Sxxxx and AT91SAM7X256.
- added 3 new methods to the PIO module: pullup(), pulldown(), ad nopullup(), their meaning is obvious.
- new shell command: mem
- new module: bit (for bit operations)
- removed UARTx, TMRx, SPIx, PWMx constants from the respectives modules, as they only waste memory space. But now the same
modules will return an error (via luaL_error) if an invalid resource ID is used. Note that this does not apply to PIO, since
PIO uses special encodings for ports/pins.
- new methods in pio: port and pin to return the port/pin encoded in a pio value.
LPC2888 board. The allocator used is dlmalloc, just as in Newlib, but it's a
newer version than can handle non-contiguous memory spaces (2.8.3, as opposed
to 2.6.4 in Newlib 1.16.0, I really have no idea why they're using such an
ancient version of dlmalloc). To use it add "allocator=multiple" to your scons
command line (default for LPC2888).
This takes care of my LPC2888 board (any many other board out there)
that have RAM both on the CPU itself and on a separate chip.
To use it add "allocator=tlsf" to your scons build command.
Even though the code for all the platform was modified, the new code
should not modify the "old" allocator behaviour.
Also added a new "mem" command to the shell, it gives information about
the current RAM state (total, used, free).
NOT YET TESTED !!! So use with care.
* platform()/cpu() returns the platform/cpu name, respectively
(instead of previously name()/cpu())
* platform interface is platform_pd_get_<cpu/platform/cpu_clock>
pd.name() is still defined to keep compatibility with samples on the
web site. It would be best for sample programs to be part of the repository
so they could be kept aligned with the code they demonstrate.
