INITIALIZING THE TMS320C5X DSK BOARD

The most important task you must perform before starting ANY application is DSK initialization. Initialization is done in software preceding the entry to your application and must be done if the Analog Interface Circuit (AIC) is to be used.

If this initialization is not done, your DSK applications will not run properly. At other times the application seems to run, but nothing will happen. For example, the TRY1.ASM code in the Users Guide does not work. You are seeing the effects of an

uninitialized DSK board.

Three things must be initialized:

1) The TMS320C50 on-chip timer,

2) The TMS320C5x serial port,

3) The Analog Interface Circuit (AIC).

This document discusses the details needed to initialize the DSK properly for your configuration.
