 '''Local Traffic Generation''': the [wiki:../LTG LTG framework] uses the scheduler to create arbitrary traffic according to the programmed inter-packet intervals
 
+== Scheduler API ==
 
+User code interacts with the scheduler via the following functions:
+
+{{{u32 wlan_mac_schedule_event(u8 scheduler_sel, u32 delay, void(*callback)())}}}:
+ * {{{scheduler_sel}}}: select the coarse (±100ms accuracy) or fine (±100µs accuracy) scheduler; must be {{{SCHEDULE_COARSE}}} or {{{SCHEDULE_FINE}}}
+ * {{{delay}}}: time in microseconds before {{{callback}}} is called
+ * {{{callback}}}: function pointer to callback to execute after {{{delay}}} µs
+ * Returns u32 {{{id}}} for new scheduler entry or {{{SCHEDULE_FAILURE}}} on failure
+
+
+{{{void wlan_mac_remove_schedule(u8 scheduler_sel, u32 id)}}}
+ * {{{scheduler_sel}}}: select the coarse (±100ms accuracy) or fine (±100µs accuracy) scheduler; must be {{{SCHEDULE_COARSE}}} or {{{SCHEDULE_FINE}}}
+ * {{{id}}}: event ID previously returned by {{{wlan_mac_schedule_event}}}
+
+== Implementation ==
+The scheduler is implemented in the [browser:ReferenceDesigns/w3_802.11/c/wlan_mac_high_framework/wlan_mac_schedule.c wlan_mac_schedule.c] file. The scheduler uses the axi_timer core attached to CPU High in interrupt mode.
