Raw Normal View History

Pong example remorphed for a require() / module () scheme. It now illustrates how to create and use a module in Lua for eLua. An LM3S platform-dependend module is created, exposing it's buttons, leds and offering some utility functions.

- LTR: even if we (obviously) can't set new keys/values in a rotable, we still respect the __newindex metamethod. This allows for interesting tricks, like the one shown below :) - complete rewrite of the PIO module. New usage: pio.PA = 10 -- set the value of PA to 10 pio.PB_1 = 1 -- set the value of pin 1 of PB to 1 local value = pio.PB -- get the value of PB local value = pio.PB_3 -- get the value of pin 3 of PB pio.PA_DIR = pio.OUTPUT/pio.INPUT - set the direction of PA pio.dir[ pio.PA ] = pio.OUTPUT/pio.INPUT - same as above pio.PA_2_DIR = pio.OUTPUT/pio.INPUT - set the direction of pin 2 of PA pio.dir[ pio.PA_2 ] = pio.OUTPUT/pio.INPUT - same as above pio.PA_PULL = pio.PULLUP/pio.PULLDOWN/pio.NOPULL - set pulls on PA pio.pull[ pio.PA ] = pio.PULLUP/pio.PULLDOWN/pio.NOPULL - same as above pio.P0_3_PULL = pio.PULLUP/pio.PULLDOWN/pio.NOPULL - set pulls on pin 3 of P0 pio.pull[ pio.P0_3 ] = pio.PULLUP/pio.PULLDOWN/pio.NOPULL - same as above - samples modified to use the new PIO syntax - bugfix in AT91SAM7X256 UART int handler - fixed yet another bug in AVR32's libc (actually replaced strcmp (which is broken on AVR32) with a custom version).
