Make sure the IO pin you are going to use for interrupt actually has interrupt feature. I encourage you to read the datasheet in order to understand much better about interrupt registers. The timer interrupt will be covered later in the timer chapter. This post will have only the input from pin change. I am not going to cover the difference between C18 and XC8 (XC8 makes your life a lot easier), but I’ll show you how to use interrupts in XC8. Now setting up interrupts is as simple as using the keyword “interrupt” before the function which should be called when an interrupt happens. With XC8, using interrupts is programmatically simple, since most of the code layout is given to you by. If it is seen like in the image below then go to step6 Step6: Click on 'Browse.' And add the compiler (xc8. C: Program Files (x86) Microchip xc8 v1.38 bin Step3: Run as administrator the.bat file Step4: Open MPLAB 8 and go on 'Project' menu - 'Select Language Toolsuite' Step5: Under the drop box it should appear 'Microchip XC8 Toolsuite'. Write assembly code, build and assemble your project with MPLAB’s wizards, then test your code with the built-in simulator and debugger. I’m sure if you reached this post in need of using interrupts (or having trouble with interrupts), then I assume you know what interrupts are and what you are trying to use.ĭownload MPLAB IDE and use the tutorial in the MPLAB IDE User’s Guide at the bottom of this page to explore how easy it is to create an application.

Interrupts! You use them to detect the change in pin status, timers, communication and so on.
