OPT3002 - ALS - ACK Issue

[Dhaya]

Hi,

     We are currently working on ALS (Ambient Light Sensor) form the manufacturer of TI. It has configured in I2C protocol. While send the slave address it give ACK signal properly but when we pass the register address (Config address 0x01), there is no ACK has received. Kindly support what changes to do, if you have idea on this.

Thanks & Regards,

Hi, 

Since you are using TI's OPT3002, I would recommend posting this question on the TI community. 

I am not familiar with this sensor, but if it does not acknowledge the register address, it may indicate the device is not ready, the wrong address is being used or there is a bus conflict.

BRs, Tomas
