This summer I’m making a serial expansion board for the HDMI2USB for use with gstreamer PTZ camera control pipeline. I will be modifying the firmware in Cypress FX2LP so that two additional USB virtual serial ports are available on HDMI2USB and I will create mappings for their end-points buffers to external hardware through the FPGA.
First virtual serial port will be used as a sink for PTZ camera control pipeline, and will be mapped inside the FPGA to a Serial Expansion Board for VHDCI on Digilent Atlys which then connects through a cable to the control port(s) of PTZ camera(s).
The other virtual serial port will be kept for future use by any other pipeline and will be mapped by the FPGA to a GPIO header on the serial expansion board for exchanging data with additional peripherals like tally lights, indicators, IR remote etc.
Lastly, this system will be integrated and tested with the existing PTZ control libraries.
The serial expansion board circuit and firmware changes will also be usable in the Numato production board design for HDMI2USB which is under development.

About me:
I’m Ayush Sagar and I'm currently pursuing masters in Power Electronics in Hyderabad, India. In free time I like watching online courses, gadget reviews and fixing and cracking-open things around. Apart from college stuff I like watching online courses, gadget reviews and fixing and cracking-open things around. I’m very excited to be working on this project with TimVideos community during this summer because among other cool things to learn in a FOSS community this will give me a gentle start on VHDL (on Xilinx Spartan 6) and USB protocols.
