Timers are one of the mostly used modules in microcontroller. Almost every system that has to be reliably produce time interval or delays will have to use timers modules. The PIC timer calculator is a cool tool will make life much simple.
If you haven’t worked with timers, I suggest you read about the timer/counter module in microcontrollers in general and then move on to read about the ones on PIC micros.
PIC Timer Calculator!
I found this great GUI tool to calculate PIC Timer preload value after you choose the necessary settings. The best part is it gives you a copy-paste code for configuration settings that was made. If you are going to be working with timers frequently then this is a really cool piece of software to have around.
This tool has options for timer parameters such as the oscillator frequency, mode, prescaler and postscaler, just graphically give it all the configurations and you will have the timer 0 preload values at your disposal.
The GUI is quite self explanatory. If you are facing any difficulties in understanding or using this tool, you probably haven’t worked extensively with timers and it not a very bright idea to start here.
Use the datasheet to fish for the bits to set to make the timer work properly. Once you feel if you are good enough in the old school way, you should not have any difficulties in using this tool.
