- malloc.c/.h are now dlmalloc.c/.h - 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. 2008-08-27 13:39:10 +00:00			`#define ABSDIFF( x, y ) ( ( x ) >= ( y ) ?

eLua now works over TCP/IP instead of serial connection. This is basically printf/scanf over TCP/IP instead of UART, so it should look&feel just like "regular" Lua, except that you don't have 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. 2008-09-18 20:22:15 +00:00			`#define UMAX( x, y ) ( ( x ) >= ( y ) ? ( x ) : ( y ) )`
