- 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 ) ?
