b90075ea0a bug fix, msp430 hw bug (undocumented): 
when in continuous/compare mode the interrupt handler may get called before CCR==TR.

behavior observed when the timer is toggled between STOP/CONT in an external interrupt handler (serial input).

possibly this problem may also affect watchdog timer/timer B

fc6d059d24 Added a clock_seconds() function prototype to core/sys/clock.h, that returns seconds in 32 bit format. On platforms like the MSP430, which has a 16 bit native datatype, this cannot be implemented with an interrupt tick that increments a 32 bit value because access is not atomic. Instead, the MSP430 code increments 16 bit seconds value and converts this into a 32 bit value through an offset calculation. If the new value is smaller than the last check, the offset is incremented by 65536. This change also means that CLOCK_CONF_SECOND must be a power of two because a modulo operation is used inside the periodic tick interrupt handler. 2008-07-07 23:38:09 +00:00

ae2073cac9 Factored out setup directory search path for source files into Makefile.include. 
- All compilers used support the -I option for setting an include search directory.

- The Contiki source tree follows the (common) approach of placing declarations (in headerf iles) in the same directory as definitions (in source files).

As a result it makes sense to use the -I compiler option for just the same set of directories used for the vpath gnumake directive.

Note: I checked several builds but nevertheless one or the other might need some additional adjustsments. Sorry for the inconvenience.
