**************************************************************************************************** ADSP-BF533 EZ-KIT Lite Video Input Example Analog Devices, Inc. DSP Division Three Technology Way Norwood, MA 02062 Date Created: 7/02/03 ____________________________________________________________________________________________________ This directory contains an example ADSP-BF533 video input project that initializes SDRAM memory, sets up the DMA configuration registers to DMA data from PPI to the SDRAM, and configures the PPI port to ITU-656 input mode. Files contained in this directory: BF533_EZ_KIT_Video_Receive_C.dpj VisualDSP++ project file PLL_Config.c C file for setting up a faster speed DMA_Config.c C file for setting up DMA configuration registers PPI_Config.c C file for setting up the PPI port SDRAM_Config.c C file for initializing SDRAM control registers Flash_Setup.c C file for setup the flash PROM to drive ADV7183 ISR_Config.c C file for initializing interrupts and the interrupt subroutine it self main.s C file for calling all setup subroutines readme.txt this project description file BF533_EZ_KIT_Video_Receive_C.dxe executable for this project ____________________________________________________________________________________________________ CONTENTS I. FUNCTIONAL DESCRIPTION II. IMPLEMENTATION DESCRIPTION III. OPERATION DESCRIPTION I. FUNCTIONAL DESCRIPTION The video input demo demonstrates the initialization of SDRAM memory and the use of the DMA and PPI to input an external analog CVBS signal on ADV7183s input AVIN1. This example utilizes SDRAM memory to store the video data. The program sets up the DMA and PPI configuration registers for input mode. for 8-bit, ITU-656, Stop Mode DMA. II. IMPLEMENTATION DESCRIPTION The main file calls: 1. the function Init_PLL() initializes the PLL to run faster. 2. the function Init_EBIU() initializes the external async port. 3. the function Init_Flash() sets up the flash GPIOs 4. the function Init_ADV() toggles the reset pin of the ADV7183 via the gp flag of the flash as well as the ADV7183 OE will be de-asserted. 5. the function printf has been implemented to delay following calls. That gives the ADV7183 time to lock to the analog signal. 6. the function Init_Interrupts() to configure the interrupt service routine. 7. the function Init_SDRAM() to initialize SDRAM memory. 8. the function Init_DMA() to initialize the DMA in stop mode. The DMA stops after 50000 transfers. For endless runs change the DMA register. 9. the function Init_PPI() to initialize the PPI. III. OPERATION DESCRIPTION - Open the project "BF533_EZ_KIT_Video_Receive_C.dpj" in the VisualDSP Integrated Development Environment (IDDE). - Under the "Project" tab, select "Build Project" (program is then loaded automatically into DSP). - change switch #6 of SW3 to on of the ADSP-BF533 EZ-KIT Lite. - Connect a video NTSC/PAL CVBS signal to the video input jack AVIN1"at the bottom right" on the ADSP-BF533 EZ-KIT Lite. - Select "Run" from the "Debug" tab on the menu bar of VisualDSP. - Hit the stop button to halt the processor - Open the Image Viewer "View/Debug Window/Image Viewer". Do following steps: -- Type start address 0X1; Horizontal Pixels = 720; Vertical Pixels = 525; Pixels per bit = 8; Stride = 2 -- Image format = Gray Scale; Hit OK.You should see the image taken
