The sketch prints the "Hello World!" text string in a slightly different way, i.e. very short, and the timer precision is extremely high.Ĭlick here to download a more sophisticated (but still simple) version of the above code (zip file). Overall, the code is very effective, i.e. TimerStart(&Timer1, 1000) // Restart the timer The following code demonstrates the use of timers: TimerReset() - Resets a currently active timer.TimerStart() - Starts a timer using a user-defined time in milliseconds.TimerInit() - Initializes all timers as defined by the user.Without going into too great detail, the structure is used by a few functions and their purpose is pretty much self-explanatory: In a next step, I created a structure as follows: I found a working solution at but modified the code slightly for ease-of-use. The first task was to create a timer interrupt routine that is being called every one millisecond (a resolution of milliseconds is sufficient for the majority of control applications). Nevertheless, since the Arduino Due comes with the power of an ARM Cortex M3 processor, it makes sense to use the Due's special capabilities and create a very precise, yet surprisingly simple timer control sketch. The above samples will work with pretty much with every Arduino board. Nevertheless, you can weave some code around these function calls to accomplish all kinds of timers, and I found two very nice examples in the Arduino Playground. The millis() and micros() functions can be used to measure the time between two events, but for industrial-style timer management that will not do. When it comes to times beyond a few milliseconds, this may cause some serious trouble when it comes to manage other processes such as reading sensors, etc. they delay the program and do virtually nothing in the meantime. The problem with the delay functions is that they do what the function name implies, i.e. The Arduino compiler provides a number of timing control functions, and they are: It may sound obvious, but there are many applications for the Arduino Due that will require at some time the control of timers. It has 54 digital input/output pins (of which 12 can be used as PWM outputs), 12 analog inputs, 4 UARTs (hardware serial ports), a 84 MHz clock, an USB OTG capable connection, 2 DAC (digital to analog), 2 TWI, a power jack, an SPI header, a JTAG header, a reset button and an erase button. It is the first Arduino board based on a 32-bit ARM core microcontroller. The Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU.
