Webb6 feb. 2014 · Setting up a PIC timer to the correct frequency can be a tricky business for the uninitiated Software Engineer (i.e. Me). So I was pretty happy when I came across this great on-line tool whereby you just type in your oscillator frequency and desired interrupt rate and it generates the setup code for you!. For example I have an 8Mhz clock and … Webb5 maj 2024 · The first button will be used to set the time delay (500ms for every push) and the second button will be used to start the timer sequence blinking. For example, if the first button is pressed thrice (500*3 = 1500ms) the delay will be set for 1.5sec and when the button two is pressed each LED will turn ON and OFF with the predefined time delay. income tax structure in india 2021
