![]() Many Arduino functions use timers, for example the time functions: delay (), millis () and micros () and delayMicroseconds (). The timer interrupts are the software interrupts generated by the timer. Here are some CCS drivers and example files which demonstrate #use timer():Ĭ:\program files\picc\examples\ex_ticks.cĬ:\program files\picc\drivers\modbus_phy_layer_rtu.cĬ:\program files\picc\examples\ex_usb_mouse. As an Arduino programmer you will have used timers and interrupts without detailed knowledge, because all the low level hardware stuff is hidden by the Arduino API. Timer Interrupts are an effective way to ensure timed events happen to the millisecond, allowing for fine-tuned clock or PWM operations, or just supplying a reliable pulse to an LED. Look at the #use timer() library and the get_ticks() function in Then reading this gives 'micros', and dividing this result by 1000 gives 'millis'. The Arduino Uno has two interrupts, interrupt 0 and interrupt 1. The first parameter is the interrupt number. ![]() The attachInterrupt () function takes three parameters. To trigger the interrupt service routine, use the attachInterrupt () function in the setup () section. Program it's interrupt to increment a second word, so you have a 32bit uSec counter available. How to Trigger an Interrupt Service Routine. If you have a chip with the RTC module, then reading this gives 'time', but on most chips this is not available.īasic solution, is to program one of the system timers to count in uSec (dividers needed will depend on your CPU clock). How do you use an Arduino timer interrupt Timer interrupts are not built-in on the Arduino platform like the external interrupt. Values would always be completely dependant on your system clock. ![]() There is no timekeeping in the PIC, till you program it. If you could point me into the right direction, it'd be very helpful for me probably an example to blink an LED without using 'delay_ms()' should do I did search the forums, but I'm NOT SURE if I found something useful. My question is "is there any such simple equivalent in PCW?" I could just call it twice to know the time difference and use it to perform actions based on time delays. This is quite useful when it comes to avoiding delays. if the program started 3 seconds ago, millis() would return 3000. In arduino, there are functions called millis() and micros(), which return the number of milliseconds and microseconds elapsed since the time the program started running.Į.g. I've worked quite a bit on the Arduino Platform and am trying to explore PIC currently. Please do not post bug reports on this forum.
