We have ADV7280 is connected with renesas S7G2.


RESET and PWRDWN pin is pulled-up to DVDDIO.

SDA and SCL pin is pulled-up  to DVDDIO by 4.7kohm.

We try to read register from 0x11(IDENT) with slave address 0x43. There is no ack from the device(ADV7280). There are other devices in the same I2C bus. Those devices are working fine.

Is there any non-os driver for ADV7280(With some microcontroller), so that we can have some reference code?
