Vietnam National University Ho Chi Minh City University of Technology Digital Signal Processing LAB REPORT Software initialization and first LED demonstrations Using TMS320C5515 eZDSPTM USB Stick Instructor: Assoc Prof Dr Thuong Le -Tien Teaching Asisstants: Chi Hieu, Quoc Huy Group 7: Dat Nguyen-Si ID: ILI11006 In-class ID: Trung Le ID: 41103857 In-class ID: February, 27th 2014 February, 27th 2014 Adventure Works Marketing Plan Lab report Table of Contents [Type text] Page February, 27th 2014 Adventure Works Marketing Plan Lab report Abstract This report outlines steps to get started with TMS320C5515 eZDSPTM USB Stick Development Tool, including Code Composer Studio installation and hardware configuration This report also presents three brief demonstrations using LEDs of the board [Type text] Page February, 27th 2014 Adventure Works Marketing Plan Lab report Introduction TMS320C5515 eZDSPTM USB Stick Development Tool is a small form factor, very low cost USB-powered DSP development tool which includes all the hardware and software needed to evaluate the industry’s lowest power 16-bit DSP : TMS320C5515 C5515 provides a foundation for a range of signal processing applications, including voice recorder, musical instruments, portable medical solutions and other consumer electronics in industrial and security applications [1] TMS320C5515 eZdsp™ USB Stick Development Tool In this subject, we use this tool to study various DSP applications First of all, we need to get familiar with related materials including CCS and example library provided with the tool [Type text] Page February, 27th 2014 Adventure Works Marketing Plan Lab report Code Composer Studio Installation steps Insert the CCSv4 DVD provided with the tool into computer’s disk drive and wait for the auto-run to start Alternatively, we can download CCS on www.ti.com to get the latest version, and then double-click on the setup file We used the second method The installation wizard window pops up Follow the instructions to go through the installation steps Plug the TMS320C5515 eZDSPTM USB Stick into the USB port on laptop Window recognizes the hardware and completes the remaining hardware installation automatically When installation has finished, double-click the shortcut icon on desktop created by the wizard Precise the workspace we wish to store all the project files Inside the program, go to Help -> Code Composer Studio Licensing Information -> choose Free license [Type text] Page February, 27th 2014 Adventure Works Marketing Plan Lab report Hardware configuration steps Inside the program, go to View -> Target configurations -> right click on User Defined -> New Target Configuration -> specify name and location -> Finish Double-click on the target icon we have just created Specify the corresponding setups for TMS320C5515 eZDSPTM USB Stick -> Save Hardware configuration for TMS320C5515 eZDSPTM USB Stick in CCS Go to File -> Import -> Existing CCS Eclipse Project -> point to the library provided with the tool, or downloaded from http://support.spectrumdigital.com/boards/usbstk5515_v2/reva/files/ usbstk5515_BSL_RevA.zip Go to View -> Project Explorer A list of example project is shown on the left of the screen Click on ‘uled’ project Go back to Target Configuration window -> right-click on the target file we have just created -> Link File to Project -> choose ‘uled’ [Type text] Page February, 27th 2014 Adventure Works Marketing Plan Lab report LEDs display demonstrations Right-shift OLEDs Open ‘uled’ project -> choose Debug icon on the toolbar (or press F11) -> click Resume The LEDs on the board should blink from left to right, one after another in loops LEDs blink from left to right demonstration on TMS320C5515 eZDSPTM USB Stick [2] [Type text] Page February, 27th 2014 Adventure Works Marketing Plan Lab report We can see the source code for this demonstration in uled_test.c as follows: #include "usbstk5515.h" #include "usbstk5515_led.h" #include "stdio.h" /* * * * * uled_test( ) * * User LED tests toggles each of the four user LEDs times * * * */ Int16 uled_test( ) { Int16 i, j; * printf(" User LED tests toggles each of the four user LEDs times\n"); SYS_EXBUSSEL = 0x6000; // Enable user LEDs on external bus USBSTK5515_ULED_init( ); /* Running LED test */ for ( j = ; j < ; j++ ) { for ( i = ; i < ; i++ ) { if ( USBSTK5515_ULED_on( i ) ) // Turn on user LED i return 1; USBSTK5515_waitusec( 50000 ); } for ( i = ; i < ; i++ ) { if ( USBSTK5515_ULED_off( i ) ) // Turn off user LED i return 2; USBSTK5515_waitusec( 50000 ); } } USBSTK5515_ULED_setall( 0x00 ); } return 0; [Type text] Page February, 27th 2014 Adventure Works Marketing Plan Lab report Left-shift OLEDs Open ‘uled’ project -> double-click on uled_test.c -> modify the loop as follows: /* Running LED test */ for ( j = ; j < ; j++ ) { for ( i = ; i < ; i++ ) { if ( USBSTK5515_ULED_on( 3-i ) ) // Turn on user LED i return 1; USBSTK5515_waitusec( 50000 ); } for ( i = ; i < ; i++ ) { if ( USBSTK5515_ULED_off( 3-i ) ) // Turn off user LED i return 2; USBSTK5515_waitusec( 50000 ); } } The LEDs now blink from right to left, one after another in loops [Type text] Page February, 27th 2014 Adventure Works Marketing Plan 10 Lab report Flashing a 4-bit counter Open ‘uled’ project -> double-click on uled_test.c -> modify the uled_test subroutine as follows: Int16 uled_test( ) { Int16 i, j; printf(" User LED tests toggles each of the four user LEDs times\n"); SYS_EXBUSSEL = 0x6000; // Enable user LEDs on external bus USBSTK5515_ULED_init( ); /* Running LED test */ while (1){ for ( j = 15 ; j >= ; j ) { USBSTK5515_ULED_setall(j); USBSTK5515_waitusec( 500000 ); } } return 0; } The LEDs now become a 4-bit counter with each LED represents one of four bits The counter counts up from to 15 and return to to start over again [Type text] Page 10 February, 27th 2014 Adventure Works Marketing Plan 11 Lab report Conclusion In this lab experiment session, we succeeded to get the Code Composer Studio installed on our laptops as well as managed to configure CCS to be compatible with TMS320C5515 eZDSPTM USB Stick We also succeeded to run our first demonstrations on the LEDs by modifying the example source codes supplied with the tool We can expand further by modifying the example codes to get the LEDs become a 4-bit counter counting down from 15 to 0, simply by replacing the line for ( j = 15 ; j >= ; j ) by for ( j = ; j >= 15 ; j++ ) in the uled_test.c file [Type text] Page 11 February, 27th 2014 Adventure Works Marketing Plan 12 Lab report References [1] Texas Instruments, C5515 eZDSP USB Stick Development Tool description and features, http://www.ti.com/tool/tmdx5515ezdsp, retrieved on February, 27th 2014 [2] sensorasia, TMS320C5515_eZdip_USB stick.MP4, http://www.youtube.com/watch? v=ZFnvH1iZoY8, retrieved on February, 27th 2014 Illustrating images of C5515 eZDSP USB Stick Development Tool are taken from http://www.ti.com All source codes in this report are taken from the usbstk5515_v1 library associated with C5515 eZDSP USB Stick Development Tool, provided by Spectrum Digital Inc [Type text] Page 12 ...
