STR91x demonstration software

Introduction

This document describes the demonstration software running on the STR910-EVAL

evaluation board, which you can use to evaluate the capabilities of the microcontroller and

the on-board peripherals.

The demonstration software contains a main application divided into various smaller

applications. The demonstration software is already stored in the embedded flash memory

of the microcontroller and can also be downloaded from http:\\www.st.com\mcu then

programmed into the STR91x internal flash.

Important note: For users with old STR9-eval boards having STR9 MCU with marking

showing "ES_D" or a value less than 618:

Revision 1.2 of the STR9 demonstration software is configured to run at 96 MHz for CPU

and FMI clock. This implies that pressing the Reset button will not restart the MCU (please

refer to the STR9 errata sheet v2.0).

In order to correct this problem, you should uncomment the following line of code in the

main.c file.

//SCU_FMICLKDivisorConfig(SCU_FMICLK_Div2);
