Breyden Wood’s Status Report for 3-27-21

For this week, I have spent the bulk of my time working on getting camera input from the camera through the FPGA to the display. I did this by first wiring up the camera to an Arduino to test that it works, then wiring it through the FPGA and interfacing it with my existing VGA driver. Interfacing between the FPGA and the camera has proven to be more challenging than we initially thought, however, we have been able to successfully read in greyscale images (still working on RGB color) and output them to the display through a small framebuffer I created (160x480x24) for testing purposes. Through this process, I have learned how to control the internal registers of the OV7670 to change image and color settings, how to interface with and read this data into the FPGA, and how to create BRAM framebuffer modules. In terms of progress, we are on track as our goal was to have the camera interface done. For this upcoming week, I plan to figure out how to make the color work correctly from the camera as well as build larger buffers using the additional memory available on the chip.
