Recommend book or sites on how to build a big project with C programming for Pic18

Hi
I have some experience on C programming but new on micro programming. I am working on a project with a Pic18 processor. There are plenty of info and examples on small C programs on the net for example: “MPLAB C Lessens for Pickit 3 debug express” and I have gone throw them. But I would like to learn and see examples for how to build a big project. I wonder if anyone can recommend a book for Pic18 family with a big programming project (C programming) using MPLAB as development tool and MCC18 compiler?

Tanks in advance!

You can try this: Programming 8-bit PIC Microcontrollers in C: with Interactive Hardware Simulation

There is a good article on AVR Freaks. It shows how to split a large project into smaller modules.

I have this book comes with a free limited edition of mikroC, but its easy to convert to C18...https://www.amazon.co.uk/Advanced-PIC-Microcontroller-Projects-RTOS/dp/0750686111

Good book
