Obsolete delay function but we implement it here since some code still uses it.
Obsolete delay function but we implement it here since some code still uses it.
The original clock_delay for the msp430 used a granularity of 2.83 usec. This approximates that delay for values up to 1456 usec. (The largest core call in leds.c uses 400).
Obsolete delay function but we implement it here since some code still uses it.

| void clock_delay_usec | ( | uint16_t | dt | ) |
Delay a given number of microseconds.
| dt | How many microseconds to delay. |
Delay a given number of microseconds.
Delay a given number of microseconds.
| len | Delay len uSecs |
See clock_init() for GPT0 Timer A's configuration
Delay a given number of microseconds.
Use the 250KHz MACA clock for longer delays to avoid interrupt effects. However that can't be used if the radio is being power cycled!

| unsigned long clock_seconds | ( | void | ) |
Get the current value of the platform seconds.
This could be the number of seconds since startup, or since a standard epoch.
Get the current value of the platform seconds.
The comparison avoids the need to disable clock interrupts for an atomic read of the four-byte variable.
| void clock_set_seconds | ( | unsigned long | sec | ) |
| clock_time_t clock_time | ( | void | ) |
Get the current clock time.
This function returns the current system clock time.
Get the current clock time.
When 16 bit it typically wraps every 10 minutes. The comparison avoids the need to disable clock interrupts for an atomic read of the multi-byte variable.
| uint32_t pic32_clock_get_peripheral_clock | ( | void | ) |
Calculate the peripheral clock.
Definition at line 96 of file pic32_clock.c.
References pic32_clock_get_system_clock().
| uint32_t pic32_clock_get_system_clock | ( | void | ) |
Calculate the system clock.

| void rtimer_arch_init | ( | void | ) |
We don't need to explicitly initialise anything but this routine is required by the API.
The Sleep Timer starts ticking automatically as soon as the device turns on. We don't need to turn on interrupts before the first call to rtimer_arch_schedule()
Definition at line 82 of file rtimer-arch.c.
| rtimer_clock_t rtimer_arch_now | ( | void | ) |
Returns the current real-time clock time.
Definition at line 96 of file rtimer-arch.c.
| void rtimer_arch_schedule | ( | rtimer_clock_t | t | ) |
Schedules an rtimer task to be triggered at time t.
| t | The time when the task will need executed. This is an absolute time, in other words the task will be executed AT time t, not IN t ticks |
Definition at line 102 of file rtimer-arch.c.

Currently simply explicitly sets the WDT interval to max interval
Definition at line 58 of file watchdog.c.
| void watchdog_periodic | ( | void | ) |
Writes the WDT clear sequence.
Due to how the SMWDTHROSC_WDCTL works, it is OK to simply write these bits rather than use RMW operations.
Definition at line 71 of file watchdog.c.
| void watchdog_reboot | ( | void | ) |
Keeps control until the WDT throws a reset signal.
Starts the WDT if not already started.
Definition at line 83 of file watchdog.c.
| void watchdog_stop | ( | void | ) |
In watchdog mode, the WDT can not be stopped.
This function is defined here to satisfy API requirements.
