- new addition to the PIO module: now you can use pin ranges in PIO expressions. For example:
gpio.PA_3_6_DIR = gpio.OUTPUT -- make pins 3-6 from PORTA outputs
gpio.PB_0_30_PULL = gpio.PULLUP -- activate pullups on all but the last pin of PORTB
gpio.PB_3_6 = 11 -- set value 10 (1011) to pins 3-6 of PB (so PB.6 == 1, PB.5 == 0, PB.4 == 1, PB.3 == 1 )
value = gpio.PB_2_9 -- read the value of pins 2-9 of PB into 'value'
Of course, one can still specify a single pin instead of a range.
This is still tested, but seems to work fine for now.
- romfs/ samples updated to work with the new module name and syntax
- small fix to buf.c (in the BUF_MOD_INCR macro).
- 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).
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.
