The next level up in complexity, and the driver solution likely to be ideal for most customers, is the IPC-Lite software drivers. This solution requires no additional setup in application code beyond adding the appropriate files listed on this slide to both the C28 and M3 projects. The ipc_lite.c source files include the function code for all IPC-Lite API functions. The ipc_util.c source files include function code for basic utility functions (such as checking IPC flag status and acknowledging or setting IPC flags) that can be used in conjunction with both IPC and IPC-Lite drivers. The M3 version of the ipc_util.c file also includes a function for calling the C28 peripheral bootloaders. The ipc.h header files include function prototypes and useful #define definitions for values either passed in as parameters to the driver functions or within the functions themselves.
