- the infinite timeout value is again represented by a special value
(not a special timer ID), but this time it's a non-negative value
- all timers in the UART module default to the system timer
- all timers in the TMR module default to the system timer
- implemented a generic system timer mechanism that can be used in
conjunction with a timer interrupt.
- implemented system timers on LM3S (tested) and STM32 (not tested).
Both are based on the Cortex M3 SysTick timer.
- added explicit support for the system timer in common_tmr.c
- all the functions in the tmr module will now use the system timer
by default (if no id is specified)
- infinite timeout will be specified by using a special timer ID
rather than using negative timeout values (this allows the timer
data type to be unsigned and increases the timer range)
- Added direct access to interrupt flags; an interrupt doesn't have to trigger a handler anymore, its flag(s) can be checked instead (platform_cpu_get_interrupt_flag).
- Added experimental C interrupt handlers support (NOT TESTED). It can be compiled and used separately from the Lua interrupt support implementation. Hint: src/elua_int.c, elua_int_set_c_handler and elua_int_get_c_handler, also BUILD_C_INT_HANDLERS (as opposed to BUILD_LUA_INT_HANDLERS).
- Added tmr.set_match_int function that sets a match interrupt on a timer (one-shot or cyclic). Also works on virtual timers. In fact, it currently works only on virtual timers, as none of the platforms have support for this operation with hardware timers.
-Added more interrupt support functions in the CPU module.
All of the above were implemented and tested on the ELUA-PUC board, and nothing else. As a side effect, THIS COMMIT BRAKES THE STR912 PORT! The port will be modified to take advantage of the new interrupt structure soon; until then, please don't update it.
channel. Smoothing support (rolling average) has been added. adcscope has
been updated to reflect these changes, and show output from 4 channels at
once.
- fix for typo in stm32/platform.c
- added virtual timers (on LM3S, AVR32 and AT91SAM7 for now)
- added interrupt handling code for AT91SAM7 and AVR32
- fixed two serious bugs that prevented the eLua image to run on both STR9 and LPC2888 (linker command file issues)
- fixed line endings (DOS->UNIX) in the STM32 library files
- fixed preprocessor errors (hopefully all of them) like #if ELUA_CPU == LM3S8962
- other minor or less than minor fixes :)
