1.2 Challenges

Migrating to the PIC32CM MCUs may present several challenges, including:

1. Core architectural differences that impact instruction sets, data handling, and code optimization.
2. Memory management strategies may require changes because PIC32CM MCUs have larger and more complex memory maps.
3. Understanding the differences between similar peripherals, such as their names, features, and configuration methods, will require additional learning.
4. Code written for PIC16F/PIC18F architectures, particularly low-level or assembly code, will not directly compatible and will require adaptation. This also applies to drivers generated by MCC Melody and MPLAB Harmony.
5. Some third-party libraries or code examples designed for PIC16F/PIC18F may not be available or directly compatible with PIC32CM. The might require fresh solutions or adaptations.
6. The documentation structures and terminologies used in PIC32CM data sheets and reference manuals may differ from those used for the PIC16F/PIC18F devices.
