Interrupts can be easily handled by using reserved word ‘interrupt’. MikroC PRO for PIC Microcontrollers implicitly declares a function ‘interrupt’ to handle interrupts which cannot be redeclared. void main() { TRISC = 0; // To configure PORTC as output port OPTION_REG.INTEDG = 1; // ...

(as seen withOSCCON) to protect the key RTCC registerRCFGCAL. A special bit (RTCWEN) must be set to allow writing to the register, but this bit requires its own special unlock sequence to be executed first. Here another built-in function of the MPLAB C compiler for the PIC24 comes ...
So there are only two options: use inline assembly language or, better, use a built-in function of the MPLAB C compiler for the PIC24. __builtin_write_OSCCONL(2); This function does perform the required unlock sequence and writes the desired value “2” to set the SOSCEN bit in ...

Add the AVR®Libc header file for interrupts. Toggle the LED in the timer overflow Interrupt Service Routine (ISR). Now that we have learned about interrupts, we are going to circle back to ourflashing LED application. Recall that in that exercise, we used a delay function to determine ho...
The sequence would be hard, if not impossible, to code in C. Even if we managed, the optimizer could disrupt it later. So there are only two options: use inline assembly language or, better, use a built-in function of the MPLAB C compiler for the PIC24....

In total, i need to receive 15 bytes of data,store it into array, set flag marking full array and pass it to the main() function. What is best practice to do such thing? Posted:31Oct2013-03:19 PM Copy to clipboard to share#1 ...
Doing so will rule out a problem with the definition of your ISR function. I still don't trust what you have written as being valid for the UART 2 Interrupt Vector. /*Remembertohave the same IPL hereasissetinthe IPL register*/
