Hello,
We need the GA6571 Programming Guide. Additionally, when we send the start condition to GA6571 with the slave address 0x5D, we receive a NACK response as shown in the picture below. We were using GT911 instead of GA6571 and there was not any issue.
I couldn't find a product title on the subject. We need urgent support.

Best regards.
