I am looking for some feedback on an appraoch that I working on for my current project. I have three software components to my project, a communication stack, the application, and a Boot Code/IAP/EEPROM Emulation section. Of the three, the application is the only part that has planned changes. The plan for the project is to have differnet features in the application available at differnt price points.

My approach was to create three different files that can be programmed separately. The idea being that if you want to add features you just need to update the application, leaving the communication and IAP/EEPROM code as is. May question is, Is this a better approach than keeping the three parts as one file?

Due to the size of the code, the communication stack and application are located in paged flash memory. The IAP/EEPROM code is in a common page. The EEPROM registers are locared in secondary flash.

Thanks in advance,

Matt Barlage
