 ===== Example ===== ===== Example =====
 +
 +This example selects MPINO-8A4R(T)-S and uses input ''P0'' and output ''P32''. Call the command on every pass through ''loop()'' without blocking it. A rising input turns the output on for 1 s; another rising edge during the pulse restarts the 1 s period.

 ===== Precautions ===== ===== Precautions =====
  
-  * Timer interrupt callbacks run inside an ISR. For safety, change only flags in the callback and perform actual control processing in ''loop()''+  * Call the timer command repeatedly in ''loop()'' so elapsed time and OFF input are processed
-  * Do not use slow or interrupt-dependent code such as ''delay()'', ''Serial'', I2C or SPI in callbacks+  * Do not share a ''timer_id'' between different timer operations; use a separate ID for each. 
-  * Normally, call ''ImodbusRTU()'' repeatedly in ''loop()''. Call it from a timer interrupt with a sufficient interval only when long ''delay()'' calls or debug output slow down ''loop()''. + 
-  * Do not use the default ''ItimerSet()'' together with ''tone()'' using Timer2 or ''analogWrite()'' on Timer2 PWM pins. +===== Built-in Commands in the Same Category ===== 
-  * Explicitly using Timer1, Timer3, Timer4 or Timer5 may conflict with PWM, analog output or high-speed counter functions using that timer. + 
-  * Configure only one ''Itimer'' callback per hardware timer. +  * [[:en-us_commands:reference:iton|Iton() View detailed description]] 
-  * Defining an ISR for the same timer directly in the sketch may conflict with ''Itimer'' operation. +  * [[:en-us_commands:reference:itof|Itof() View detailed description]] 
-  * ''ItimerStopAll()'' stops only hardware interrupt timers. It does not reset PLC-style timer states such as ''Iton'', ''Itof'' or ''Itmr''.+  * [[:en-us_commands:reference:itmon|Itmon() View detailed description]] 
 +  * [[:en-us_commands:reference:itmr|Itmr() View detailed description]]
