Zyboard Z7 I2C Communication with Pcam 5c

[marvin]

Hello,

i am implementing an I2C communication from my FPGA to the Pcam 5c registers. I have written my own I2C code in VHDL. I am Now trying to read a specific Register of the Cam to confirm the Communication and see the right Default value in the Cam Registers.

On my attached Image you can see the SCL Line and my input and Output SDA Line the Upper SDA Line shows how after sending the Adress Information the SDA Line just Stays High whatever i send. During the ACKs the Line Also STays High indicating that my Camera is not reacting at all.

Hi @marvin,

The only advice I can readily offer is take a look at the existing demo that we have available on our GitHub (https://github.com/Digilent/Zybo-Z7-20-pcam-5c) with the material in the /sdk/appsrc/ folder probably being the material that you want to look at.

Thanks,
JColvin
