hello: Hello: i am using ov7690 with at91sam usin MCK at 12.3MHz. but for testing purpose i am using I2C at 153KHz from atmega2560 for SCCB. I can read any register from ov7690 but I can't write to any register. the response is correct i.e. status register of TWI of atmega2560 depicts correcr value, meaning it sends data.
but when i read back the value from that register the old valure retains...
what can be the problem??
