nvt-se 7543d53603 Ensure that the UART port is available before writing 2010-03-03 23:18:58 +00:00
adamdunkels 465125c5e7 Added support for 32-bit clock ticks: when reading the 32-bit value, make sure that it does not change between readouts to avoid reading right in the middle of it being updated 2010-02-23 18:41:20 +00:00
adamdunkels 953a8c2015 Turn off timer before updating - needed to avoid bugs in ContikiMAC - not 100% sure why 2010-02-18 22:15:54 +00:00
adamdunkels 4ff6b5460a Removed safeguards around the update code for the timer; turns out they weren't needed (but instead triggered a bug in MSPsim) 2010-01-30 14:03:35 +00:00
adamdunkels dbacf3e781 Values altered in interrupt handlers should be volatile 2010-01-26 10:20:16 +00:00
adamdunkels 5a03e4e6ad Bugfix: changed #ifdef to #if, otherwise the SFD code would be enabled anyway 2010-01-19 20:35:41 +00:00
adamdunkels 9d751da8e5 Disable SFD interrupt by default 2010-01-19 13:11:23 +00:00

adamdunkels f9260c4fae Enable interrupts during the periodic clock processing to allow rtimers to execute on top of the clock 2009-12-08 23:40:14 +00:00
adamdunkels a4df6e0fbf Remove the read from TAIV - this should not be done for TIMERA0 interrupts (in fact, doing so messes up the other timer a interrupts, like the clock tick...) 2009-12-08 23:39:45 +00:00

fros4943 53d03aa924 uart correction values for 3.9Mhz (default sky freq.) 2009-10-27 16:25:28 +00:00
fros4943 b0291ca5a8 bug fix: wake up MSP430 when leaving rtimer interrupt if the rtimer polled a process.
thanks to Marco Vedovati for finding the bug

fros4943 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

fros4943 3ec170cdf5 added empty mtarch_stop() 2008-08-27 13:10:29 +00:00
adamdunkels 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
