Nadiagiza Posted October 27, 2014 Report Share Posted October 27, 2014 Hello, i've read about fpga project at http://hamsterworks.co.nz/mediawiki/index.php/OV7670_cameraand then i have been tryring to compile and synthesize the vhdl program by myself. If i checked syntax one by one, there's no problem (no error). But, when i try to synthesize, the result always not successful because there's no syntax in frame buffer module. So, i'm looking for help about how to fix this problem. Then, i also want to know about what is "IP Block Memory Generator" that the project writer's said at hamsterwork. I am using OV7670 camera module and Nexys 4 FPGA Board. And i dont know how to connect OV7670 to nexys 4 board. Please help me,thank you Quote Link to comment Share on other sites More sharing options...
hamster Posted October 29, 2014 Report Share Posted October 29, 2014 For the frame buffer you will need to add an "IP Core" to your project. The instructions at http://www.dejazzer.com/ee478/labs/lab5_mem_internal.pdf should be enough hints to get you started. I can't publish the code on my WIki as it is © Xilinx, and the resulting files will be different for your board than they are for mine.
