Functions include initialization, set prescaler, calibrated pause function (in milliseconds), attaching and detaching of user functions to interrupts, overflow counters, PWM. Arbitrary frequency generation has been moved to the Pulse Library.</dd></dl> |
||
| 14 | <dl compact><dt><b>About Timers</b></dt><dd>The Atmel AVR-series processors each contain at least one hardware timer/counter. Many of the processors contain 2 or 3 timers. Generally speaking, a timer is a hardware counter inside the processor which counts at a rate related to the main CPU clock frequency. Because the counter value increasing (counting up) at a precise rate, we can use it as a timer to create or measure precise delays, schedule events, or generate signals of a certain frequency or pulse-width. </dd></dl> |
||
| 15 | <dl compact><dt><b></b></dt><dd>As an example, the ATmega163 processor has 3 timer/counters. Timer0, Timer1, and Timer2 are 8, 16, and 8 bits wide respectively. This means that they overflow, or roll over back to zero, at a count value of 256 for 8bits or 65536 for 16bits. A prescaler is avaiable for each timer, and the prescaler allows you to pre-divide the main CPU clock rate down to a slower speed before feeding it to the counting input of a timer. For example, if the CPU clock frequency is 3.69MHz, and Timer0's prescaler is set to divide-by-8, then Timer0 will "tic" at 3690000/8 = 461250Hz. Because Timer0 is an 8bit timer, it will count to 256 in just 256/461250Hz = 0.555ms. In fact, when it hits 255, it will overflow and start again at zero. In this case, Timer0 will overflow 461250/256 = 1801.76 times per second. </dd></dl> |
||
| 16 | <dl compact><dt><b></b></dt><dd>Timer0 can be used a number of ways simultaneously. First, the value of the timer can be read by accessing the CPU register <code>TCNT0</code>. We could, for example, figure out how long it takes to execute a C command by recording the value of <code>TCNT0</code> before and after execution, then subtract (after-before) = time elapsed. Or we can enable the overflow interrupt which goes off every time T0 overflows and count out longer delays (multiple overflows), or execute a special periodic function at every overflow. </dd></dl> |
||
| 17 | <dl compact><dt><b></b></dt><dd>The other timers (Timer1 and Timer2) offer all the abilities of Timer0 and many more features. Both T1 and T2 can operate as general-purpose timers, but T1 has special hardware allowing it to generate PWM signals, while T2 is specially designed to help count out real time (like hours, minutes, seconds). See the Timer/Counter section of the processor datasheet for more info. </dd></dl> |
