Part Number: OPT3002

Tool/software:

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.

Hi Vignesh,

I wanted to give a heads up that our engineer is out of office so should be able to get back to you next week on this.

Best,

Alex

Hi Vignesh,

Thank you for posting to the Sensing forum.

Can you please provide oscilloscope or logic analyzer captures of the failing I2C transactions? Is this behavior being observed on more than one device?

Best regards,
Nicole
