Hello. I can not initialize the adv7180 adc over i2c - no akcnowledgement returns when i write its address. The "reset" is tied to '1', also tried to follow datasheet (5ms reset -> program) it does not affect. Any ideas what can be wrong?
The address is (according to de2 manual) 0x40. One bit shift to the left + write bit = 0x80. Also, when i register the isr, the first interrupt occures because of arbitration lost it might mean something or simply core bug i don't know.
IOWR_8DIRECT(I2C_BASE,OC_I2C_TXR,0x80); //write slave address+write bit
IOWR_8DIRECT(I2C_BASE,OC_I2C_CR,0x90); //set STA, set WR
