STR73x Software Library

STMicroelectronics provides an extensive software library for the STR73x device series. The library is ported to MDK-ARM and the RealView Compiler, and is available in the folder ...\ARM\RV31\LIB\ST.

The STR73x Software Library is a software collection for the STR73x peripherals. The library contains a set of functions for each peripheral. STMicroelectronics provides detailed documentation in the STR73x Software Library Users Manual.

The STR73x Software Library is available in three pre-build versions (source code is in a sub-folder):

• STR73x.LIB: fast and efficient interrupt function handling (Keil-Style). This is the preferred library when starting new projects.
• STR73xD.LIB: (Debug Version) STMicroelectronics specific interrupt handling and debug variables for peripherals. Because the Keil µVision Debugger provides detailed outputs for all on-chip peripherals, this library is not required when you are using the Keil µVision Debugger.
• STR73xR.LIB: (Release Version) STMicroelectronics specific interrupt handling without debug variables. The Keil RTX does not work with STMicroelectronics interrupt handling, therefore, do not use this library with the Keil RTX.

Note

• If you use this library for different hardware, you may need to change the settings in the 73x_conf.h file and re-build the library using the µVision project.
• If you use any STMicroelectronics library functions, be sure to include the header file, 73x_lib.H, since it contains the definitions for the STR73x Software Library functions and macros.

Usage

When using the STMicroelectronics specific interrupt handling, you need to add a copy of the source file ...\ARM\LIB\RV30\ST\STR730\Interrupts\73x_it.c. This file contains all interrupt functions. Note It is strongly recommended that you copy this file to your project folder.
