-^ Command ^ Description ^
+Configure and control a hardware timer that calls a function periodically.
-| ''ItimerSet(intervalMs, callback)'' | Sets the default timer's interval and callback. |
-| ''ItimerSet(timerNo, intervalMs, callback)'' | Specifies the hardware timer to use. |
-| ''ItimerStart()'', ''ItimerStart(timerNo)'' | Starts the configured timer. |
-| ''ItimerStop()'', ''ItimerStop(timerNo)'' | Stops the timer. |
-| ''ItimerStopAll()'' | Stops all callback timers. |
-| ''ItimerState()'', ''ItimerState(timerNo)'' | Returns the running state. |

+  * [[:en-us_commands:reference:itimerstart|ItimerStart()]] — Starts the configured callback timer.
-void onTimer() { task = true; }
+  * [[:en-us_commands:reference:itimerstop|ItimerStop()]] — Stops the default or specified callback timer.
-void setup() { ItimerSet(100, onTimer); ItimerStart(); }
+  * [[:en-us_commands:reference:itimerstopall|ItimerStopAll()]] — Stops all running callback timers.
-void loop() { if (task) { task = false; /* Actual work */ } }
+  * [[:en-us_commands:reference:itimerstate|ItimerState()]] — Returns the running state of the default or specified callback timer.

-Callbacks run in interrupts. Change only flags in callbacks; do not use ''delay()'', Serial, I²C, SPI or lengthy calculations. Also check whether the timer is shared with PWM.
