mipi-demo

Live stream frames from a Raspberry Pi Camera v1.1 (OV5647) over HDMI.

Cumulative demonstration of a year-long journey working on the following projects:

• hdl-util/hdmi: video/audio transmission over HDMI
• hdl-util/mipi-ccs: camera control with MIPI CCS
  • hdl-util/i2c: I2C master
• hdl-util/mipi-csi-2: camera video reception with MIPI CSI 2
• hdl-util/sdram-controller: generic SDRAM controller
• hdl-util/clock-domain-crossing: utilities for clock domain crossing on FPGAs
  • hdl-util/gray-code: arbitrary width Gray codes

Demo

Picture taken with a Pixel 3a of an OV5647 video stream on an LG 4K monitor at 640x480 resolution:

Please forgive the horrible focus of the image, I'm using a knockoff OV5647 module with fixed-focus. The image is received in RAW8 format and hasn't been processed yet, hence the lack of color.

What's next?

• Demosaicing
• IMX219 control
  • This is commonly available as the Raspberry Pi Camera Module v2
• SDRAM controller improvements
• much more!

Special thanks
