Hi Coder Panda,

    Until now, we don't have the combined application about KEA and PCA8534Afor your reference. But don't worry.

   Actually, it's not difficult to realize it, at first, you need to prepare two steps:

  1. Prepare the KEA128 I2C driver

     This driver, you can refer to our official code, please download it from this link:

     https://www.nxp.com/downloads/en/device-drivers/SDK-DRIVER-FRDM-KEA-S32DS.zip 

     This is the S32DS project, I2C code can be found from this folder:

Quick Start Package v8\Code Project Examples and Sample Drivers (Evaluation Grade Only)\FRDM-KEAZ128\Driver Test SW for KEAZ128\Driver Test SW for KEAZ128

   2. Read PCA8534A  LCD datasheet very carefully,  learn what the I2C command and data flow you need to operation.

    https://www.nxp.com/docs/en/data-sheet/PCA8534A.pdf 

   There also have an application note for your reference:

    https://www.nxp.com/docs/en/application-note/AN11494.pdf 

    You can refer to the document, then write the according sample code based on the KEA128 I2C driver.

Please try it on your side.

Wish it helps you!


Have a great day,
Kerry
