Digital Systems Design lab Report
h2o// Sound.h // This module contains the SysTick ISR that plays sound // Runs on LM4F120 or TM4C123 // Program written by: put your names here // Date Created: 8/25/2013 // Last Modified: 10/9/2013 // Section 1-2pm TA: Saugata Bhattacharyya // Lab number: 5 // Hardware connections // Header files contain the prototypes for public functions // this file explains what the module does // **************Sound_Init********************* // Initialize Systick periodic interrupts // Called once, with sound initially off // Input: interrupt period // Units to be determined by YOU // Maximum to be determined by YOU // Minimum to be determined by YOU // Output: none void Sound_Init(unsigned long period); // **************Sound_Play********************* // Start sound output, and set Systick interrupt period // Input: interrupt period // Units to be determined by YOU // Maximum to be determined by YOU // Minimum to be determined by YOU // input of zero disable sound output // Output: none void Sound_Play(unsigned long period);
