The Motorola Embedded SDK is a collection of APIs, libraries, services, rules and guidelines. This
software infrastructure is designed to let DSP5680x software developers create high-level, efficient,
portable code. The application code is available in the SDK. This chapter describes how the PM
synchronous motor vector control application is written under the SDK.
The PM synchronous motor vector control application uses the following drivers:
All drivers are included in bsp.lib library.
The PM synchronous motor vector control application uses the following library functions:
The purpose of the appconfig.h file is to provide a mechanism for overwriting default configuration
settings, which are defined in the config.h file.
There are two appconfig.h files. The first appconfig.h file is dedicated for External RAM
(..\ConfigExtRam directory) and second one is dedicated for Flash memory (..\ConfigFlash directory).
In the PM synchronous motor vector control application, both files are identical, with these exceptions:

The appconfig.h for the ExtRAM target contains a definition of the RAM memory support
The appconfig.h for the Flash target contains a definition of the FLASH support
The appconfig.h for the ExtRAM target contains a PC master software recorder buffer 25000
samples long, while appconfig.h for the Flash target contains a PC master software recorder
buffer for only 100 samples, due to the limited Flash memory size
The appconfig.h for the DSP56F805EVM and DSP56F807EVM contains the definition of a
switch driver, while the appconfig.h for the DSP56F803EVM does not
