+
+ void ao_panic(uint8_t reason)
+
+ Any fatal error should call this function, which can
+ display the error code in some cryptic fashion.
+
+ void ao_wake_task(struct ao_task *task)
+
+ Wake the task as if the wchan it is waiting on had
+ been signalled.
+
+ void ao_alarm(uint16_t delay)
+
+ Queue an alarm to expire 'delay' ticks in the future.
+ The alarm will cause the task to wake from ao_sleep
+ and return 1. Alarms are cancelled if the task is
+ awoken by ao_wakeup or ao_wake_task.
+
+ void ao_exit(void)
+
+ Stop the current task and remove it from the list of
+ available tasks.
+
+Timer API
+
+ * Regular timer ticks (at 100Hz, by default)
+ * All time values are in ticks
+
+ uint16_t ao_time(void)
+
+ Returns the curent tick count
+
+ void ao_delay(uint16_t delay)
+
+ Suspend task execution for 'delay' ticks.
+
+DMA API
+
+ * Static DMA entry allocation
+
+ uint8_t ao_dma_alloc(uint8_t *done)
+
+ Allocates one of the 5 DMA units on the cc1111
+ processor. When this DMA unit is finished, it will
+ set *done to 1 and wakeup anyone waiting on that.
+
+ void ao_dma_set_transfer(uint8_t id, void *src, void *dst,
+ uint16_t count, uint8_t cfg0, uint8_t cfg1)
+
+ Prepares the specified DMA unit for operation.
+
+ void ao_dma_start(uint8_t id)
+
+ Start DMA on the specified channel.
+
+ void ao_dma_trigger(uint8_t id)
+
+ Manually trigger a DMA channel
+
+ void ao_dma_abort(uint8_t id)
+
+ Abort a pending DMA transfer, signalling
+ that by setting the associated 'done' to
+ AO_DMA_ABORTED and waking any task
+ sleeping on that.
