As usual because the lack of power from Arduino. :D<br /> I'm really interested in the 4 channels Timers for my final application, but in my initial tests with small pieces of code for familiarization, I got stuck in the Timers Functions.<br /> I already manage to have the Timers working, but now I don't know what's wrong with the following code because even with TIMER_CH1 set to 1/5 of the overflow value (1 and 5sec), the BOARD_LED flash at 5 sec. rate (Overflow value)...</p> <p>Can you please let mw know what's wrong?!<br /> IDE v0.0.12</p> <pre><code>void Interrupt_Fo_Step(void); HardwareTimer Timer_Fo(1); //Set Timer_Fo to Timer1 int temp=0; void setup() { pinMode(BOARD_LED_PIN, OUTPUT); Timer_Fo.setMode(TIMER_CH1, TIMER_OUTPUT_COMPARE); // Timer_Fo.pause(); Timer_Fo.setCount(0); Timer_Fo.setPrescaleFactor(7200); //Prescale 7200 -&gt; 0.01Mhz -&gt; 100us Timer_Fo.setOverflow(50000); //50000*100us = 5sec Timer_Fo.setCompare(TIMER_CH1, 10000); //10000*100us = 1sec Timer_Fo.attachInterrupt(TIMER_CH1, Interrupt_Fo_Step); Timer_Fo.refresh(); Timer_Fo.resume(); } void loop() { temp++; } void Interrupt_Fo_Step(void) { toggleLED(); }</code></pre>
