I interfaced the PCA8565TS with TWR-K20D72M board using I2C. to read/write first i send the start condition after that i send the slave address(0xA2) with write option then i not get acknowledgement from PCA8565TS this is the issue. i also tried with SCL 100 khz and 400 khz but in both cases i not got acknowledgement form PCA8565TS. i also attached my code for your reference. so please help me so that i can read and write with PCA8565TS.


Thank You
