Hi,

I am confused and not sure how to interface PCA8534A LCD Driver with KEA128 MCU via I2C. Can anyone please help me with the coding part?

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
