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.
You may refer to the TWR-K20_MMA8451Q_BasicReading sampleproject attached to this response.
This sample project for CodeWarrior performs a basic reading of the MMA8451Q accelerometer included on the TWR-K20D72M. You can use the I2C.c and I2C.h files in order to read and write to the PCA8565TS.
Please be aware that pull-up resistors must be placed at the I2C lines.
I hope this information will be useful for you.
If I misunderstood your question, feel free to let me know. I will be glad to help.
Have a great day.
