SDK Implementation
7.4 Interrupts
7.5 PC Master Software
The SDK serves the interrupt routine calls and automatically clears interrupt flags. The user defines the
callback functions called during interrupts. The callback functions are assigned during driver
initialization - open(). Callback function assignment is defined as one item of the initialization
structure which is used as a parameter of the function open(). Some drivers define the callback
function in the appconfig.h file.
PC master software was designed to provide an application debugging, diagnostic and demonstration
tool for the development of algorithms and applications. It runs on a PC connected to the DSP EVM
via an RS232 serial cable. A small program resident in the DSP communicates with the PC master
software to parse commands, return status information to the PC and process control information from
the PC. PC master software, executing on a PC, uses part of Microsoft Internet Explorer as the user
interface.
PC master software is part of the Motorola Embedded SDK and may be selectively installed during
SDK installation.
To enable PC master software operation on the DSP target board application, the following lines must
be added to the appconfig.h file:
This automatically includes the SCI driver and installs all necessary services.
The default baud rate of the SCI communication is 9600Bd. It is set automatically by the PC master
software driver and can be changed if needed.
A detailed description of PC master software is provided by the dedicated User’s Manual [12].
The 3-phase PM Synchronous motor control application utilizes PC master software for remote control
from the PC. It enables the user to:
