hi,
im trying to use the i2c opensource IPCore to control my CMOS image sensor through i2c interface. The sensor can only work as a i2c slave. it does not contain any pullups internally for scl/sda, so i add them with in the FPGA ( spartan 3 ). i dont use any external resistors for this. Is this acceptable?
when monitored by the chipScope logic analyzer, it seems like the sensor does not acknowlege when i write the device address Plus write bit. im sure the device address i sent is correct. the sensor im using is KAC-9630 from Kodak. Please let me know if someone can figure this out.
Thank You. CMOS
