ADSP-BF535 EZ-KIT Lite rtc Demo Analog Devices, Inc. DSP Division Three Technology Way P.O. Box 9106 Norwood, MA 02062 Date Created: 1/30/02 This directory contains example ADSP-BF535 code that demonstrates the use of the real time clock and general purpose I/O pins by blinking LEDs on the board upon a seconds interrupt. Files contained in this directory: readme.txt this file rtc.asm assembly file for the real time clock routine rtc.dpj VisualDSP++ project file ADSP-BF535_asm.ldf linker description file _________________________________________________________________ CONTENTS I. FUNCTION/ALGORITHM DESCRIPTION II. IMPLEMENTATION DESCRIPTION III. OPERATION DESCRIPTION I. FUNCTION/ALGORITHM DESCRIPTION The rtc demo contains an implementation of a subroutine that utilizes the real time clock to generate an interrupt every second. LED 1 blinks when the seconds interrupt is processed. II. IMPLEMENTATION DESCRIPTION The ADSP-BF535 is loaded with the rtc program. The main modules perform the following: 1. The GP I/O PF1 is set to output. 2. The real time clock seconds interrupt is enabled. 3. Program code remains in a waiting loop. 4. Upon seconds interrupt generation, program flow jumps to interrupt service routine. 5. In interrupt service routine, LED 1 is programmed to blink. 6. Upon completion of interrupt service routine, program flow jumps back to waiting loop. 7. Steps 4, 5, 6, and 7 repeat. III. OPERATION DESCRIPTION - Open the project "rtc.dpj" in the VisualDSP Integrated Development and Debugger Environment (IDDE). - Under the "Project" tab, select "Build Project". - Open a ADSP-BF535 EZ-KIT Lite session in the Debugger. - Load "rtc.DXE" - Place breakpoints as desired to see the operation of the program. - Focus on the ADSP-BF535 and select "RUN" from the menu bar. - View the LEDs on the EZ-KIT Lite to see the real time clock in action.
