Part Number: TMP102EVM

Hi Sir,

We are use the USB2ANY to Read TMP102EVM data, But Always response NAK.

We try the Address 48/49/4A/4B & Frequence 10k/100k/400k no improvement.

What have we missed?

Hi Hugo,

You should be able to read the TMP102EVM coupon board using a USB2ANY controller in this manner. Your I2C transaction also looks correct.

As a sanity check, can you verify using a multi-meter that the TMP102 is correctly receiving power?

Best Regards,
Brandon Fisher
