Porting the S/UNI-4x622 Driver

7PORTING THE S/UNI-4X622 DRIVER

This section outlines how to port the S/UNI-4x622 device driver to your hardware and OS platform. However, this manual can offer only guidelines for porting the S/UNI-4x622 driver because each platform and application is unique.

7.1 Driver Source Files

The C source files listed in the next table contain the code for the S/UNI-4x622 driver. You may need to modify the code or develop additional code. The code is in the form of constants, macros, and functions. For the ease of porting, the code is grouped into source files (src) and include files (inc). The src files contain the functions and the inc files contain the constants and macros.

7.2 Driver Porting Procedures

The following procedures summarize how to port the S/UNI-4x622 driver to your platform. The subsequent sections describe these procedures in more detail.

To port the S/UNI-4x622 driver to your platform:

Procedure 1: Port the driver’s OS extensions

Procedure 2: Port the driver to your hardware platform

Procedure 3: Port the driver’s application-specific elements

Procedure 4: Build the driver

Porting Assumptions

The following porting assumptions have been made:

•It is assumed that RAM assigned to the driver’s static variables is initialized to ZERO before any driver function is called.

•It is assumed that a RAM stack of 4K is available to all of the driver’s non-ISR functions and that a RAM stack of 1K is available to the driver’s ISR functions.

•It is assumed that there is no memory management or MMU in the system or that all accesses by the driver, to memory or hardware can be direct.
