Creating hex file problem

[Navneet]

Please help me out in creating the hex file for this code. I have tried using MPLAB using xc 8 compiler. but its showing error. timers.h header file is not found. If possible please help me in converting this to hex file. i need it urgently for my final semester project

Check whether the name given to the file (timers.h) and the header you used are with same spelling and have the header (timers.h) file and c file in the same folder. check with this and execute.

[Ashutosh Bhatt]

you may have to include timer.h file in root directory
