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. This chapter describes how the AC V/Hz motor control application is written under
SDK.
The AC V/Hz motor control application uses the following drivers:
All drivers except the timer driver are included in bsp.lib library. The timer driver is included in sys.lib
library.
The AC V/Hz motor 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 case of AC V/Hz motor control application both files are identical.
The appconfig.h file is divided into two sections. The first section defines which components of SDK
libraries are included to application, the second part overwrites standard setting of components during
their initialization.
Each peripheral on the DSP chip or on the EVM board is accessible through a driver. The driver
initialization of all used peripheral is described in this chapter. For detailed description of drivers see
document Embedded SDK Targeting Motorola DSP5680x Platform.
To use the driver, the following steps must be completed.
