elua_mmc.c uses the virtual timer tick to implement its timeout delays,
and needs MMCFS_TICK_HZ to have the same value as VTMR_FREQ_HZ.
This corrects the mismatch on AVR32 platforms and adds a check to
validate.h to ensure that it remains so.
MMCFS timeouts work by counting ticks of the virtual timer, which is
free-running and could tick immediately, giving a zero timeout.
This fixes the calculation of the number of ticks to wait for to set up
an N-millisecond timeout, ensuring that the actual timeout used is >= N.
Tabs have been creeping in to eLua's source files, sometimes representing
2 characters, sometimes 8. This patch replaces them all with the appropriate
number of spaces, according to the context.
This only fixes files that were written specifically for eLua, not the
manufacturers' SDK source files that were simply imported into the tree.
The return value from tmr.getmaxdelay() is always passed to
lua_pushinteger(), which turns the top half of the unsigned numbers into
negative values. This always used to bite getmaxdelay(tmr.VIRT0) and can bite
tmr.gettimediff(0, small, large).
Fixes bug #229 in the old tracker.
To get round the inadequacies of the AVR32 "TWI" hardware, this implements
I2C as a bit-banging interface, currently handling a single channel only.
Tested on EVK1100 and Mizar32. "Should work" on EVK1101 if the 2-line change
is made to evk1101_conf.h
The AVR32 GPIO resgiter map presents each GPIO register in four memory
locations which, respectively, read/write, set, clear and toggle bits
in the underlying hardware register.
This patch makes the AVR32 GPIO driving code use that register set
instead of reading, toggling bits and rewriting the registers, which required
a helper layer to make the necessary bit-twiddling generic.
returning to a 120KB config by default, which works on all Mizar32 platforms
(already OKed with Nuccio).
Automate the selection of features for the 128KB and 256/512KB versions by
checking the value of ELUA_CPU
Now the build system will automatically include all the files in
romfs/ (except .gitignore) in the ROM filesystem. Remember that the
files in romfs/ should NOT be under source control.
