1.2 Challenges

Migrating to PIC32CM MCUs may come with 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. Differences between similar peripherals—including names, features and configuration methods—will require additional learning.
4. Code written for AVR architectures (especially low-level or assembly code) will not be directly compatible and will require adaptation. This also applies to drivers generated by MCC Melody and Harmony.
5. Some third-party libraries or code examples for AVR may not be available or directly compatible with PIC32CM, requiring fresh solutions or adaptations.
6. Documentation structures and terminologies in PIC32CM data sheets and reference manuals may differ from those for AVR devices.
