Hi, I am trying to configure the registers on the MT9T001 Image sensor using a Spartan3 board.
I fed a 50MHz to the SCLK, the SDATA is pull-up by 3.3V, and after feeding the start bit and 16bit address, it does not reply with an acknowledge bit. I read the acknowledge by setting the I/O as 'Z'. I am wondering if I am doing the tri-state correctly.
Thanks.
